CF CoreProof Field

One question in, one tap out

Starting a site asks you one thing — a template, or nothing at all — and creates nothing until you answer. This walks you through what happens after that: capturing, then finishing, then building a template of your own, then the block catalogue. Every screen here is a picture of the running app.

Part 1 · A site, start to report Part 2 · A template — about 15 minutes Part 3 · Blocks 45 screenshots, all from the running app

First, your account

On a device that has never been signed in, the first screen is not your sites — it is a sign-in door, and nothing is behind it until you go through.

The CoreProof Field sign-in screen, with an email address box, a password box, and buttons reading Sign in, Email me a code instead and Forgot password
The whole app until somebody signs in. There is no rail, no Sites, no Settings — every address you type lands here instead. No account yet? Create an account, at the bottom of the door. If you would rather not keep a password, Email me a code instead signs you in with a one-time code.

It is a once-only errand. The line under the heading — Once, and the app works offline after that — is the promise: after this you can work all day in a basement with no signal.

The Create an account screen, asking for an email address, a password, your name and your company
Four boxes, and all four are asked for. The line under them says why the last two are not optional: they print on every report you export, so a report is never authorless. Both stay editable later, on Account.

Your name and company are asked here because they print

The sign-up card says so itself: “Your name and company print on every report you export — a report is never authorless. Both stay editable on the Account screen.” Nothing is verified; a report prints what you typed. Leave them and the report's cover says it is going out with no author.

On a device that already holds work, the first account claims it

Signing in on an empty device is uneventful. Signing in on a device that already has sites and templates on it takes them over — they become that account's. The door only warns you about this when there is actually something on the device to take, so on a shared tablet sign in as yourself first.

The one idea

If you take away nothing else, take this: a site is a job. A template is the shape of a job.

A template says what gets asked, what order the screen puts things in, and what the PDF prints. It holds no answers — no photos, no notes, no site name. When you make a site from a template, the site takes its own copy of that shape.

Why that matters

Because it is a copy, editing a template next month cannot reach a survey you have already done — and tidying up a site cannot damage the template it came from. You are free to experiment. Nothing you do in Templates can break existing work.

You do not need a template to start. When you tap New site the app asks once — Just start or Start from a template — and nothing is created until you answer. Just start gives you notes, photos, a cover page and plans with nothing assumed, and you can give that site a shape, or save the shape it grew into, whenever you like.

Finding your way around

Five places, down the left-hand side. That is the whole app.

  • Sites — your jobs. Each one holds its notes, photos, floor plans and its own report.
  • Templates — the shapes on this device, plus the note types a new site starts with.
  • Blocks — every symbol the app can draw, and any you have drawn yourself.
  • Settings — units, theme, and restoring a .coreproof backup.
  • Account — the account you signed in with, and a Pro licence if you hold one.
The Your sites screen on a brand-new device: an empty list, the rail on the left reading Sites, Templates, Blocks, Settings and Account, and a New site button top right
A brand-new device. One button you can press. Note the line about restoring a .coreproof backup — that is how you bring a site over from another machine, and it lives in Settings, not here.

Everything lives on this device

Your sites and templates are stored in this browser, on this machine — the heading says Everything is stored on this device and means it. The way to move work to another device, or to keep a copy, is to export a file.

Part 1

Start a site and capture it


There is no set-up step to get through. The interesting part of this section is not how a site is made — one question and a tap — but what you do in the hour after it.

1

Tap New site, and answer one question

The app asks whether you want a template or not, and nothing is created until you answer — back out and there is no half-made site on your list. There is still no panel and no name box.

The Start a new site card: the line Nothing is created until you choose, above two large choices — Just start, described as a blank site for notes photos and a plan, and Start from a template
Just start is first because it is what most taps want. The card says “Nothing is created until you choose.” and means it.

Start from a template opens the shapes on this device. Each is described by what it asks and what it hands over, because a name alone is not enough to tell two of your own shapes apart six months later.

The template list inside the same card: rows for the shapes on this device, each with its name and a line reading what it asks and what it hands over, and a Back button
The examples a new install ships with, and anything you have saved. Back returns to the two answers; nothing has been created yet either way.

Take Just start and you land on the site's own page, able to photograph something before you have decided what the building is called. It is named New building for now, and the app offers you the rename later, at the one moment the name starts to matter — when a report is about to print it.

The site page immediately after choosing Just start: the heading New building, No address recorded, the progress meter, and the Site notes and Site photos cards
Header buttons: Set up, Delete, Finish. Under them is the progress meter, and under that the cards this site's template asks for.

The first time you ever do this, a message appears at the top of the screen. It is worth reading once, because it is the app's whole position on location.

The first-run message about location: creating a site notes where your device is, once, and each photo notes where it was taken, kept on this device
Once for the site, once per photo, kept on this device with your work so it can be placed on a map. You are never tracked continuously. It appears once and then never again.
2

Read the progress meter

The strip pinned under the header is one segment per card, in the order the page runs. Each segment is a tap target: tapping it takes you to that card. It never blocks anything — an outstanding requirement shows as an amber number, not a lock.

The progress meter on a fresh site: four segments named Site notes, Site photos, Cover page and Plans, each with a hatched grey bar and no count
A fresh site. All four bars are hatched, and that is not “nothing done yet”.

Hatched means there is nothing to count

A card like Site notes has no target — there is no right number of notes, so there is no fraction to draw. A hatched bar says exactly that. An empty bar would have claimed you were 0% through work that does not exist, which is why you will never see one.

Give a site a template that asks questions and the same strip starts carrying real numbers. A set of questions shows answered / asked and fills its bar to match; an item checklist shows what you have recorded.

The progress meter on a site using the Inspection register template: seven segments, two showing 0 of 3 with a bar, a Checklist segment showing a count, and four hatched
Three kinds of segment on one strip. Before you start 0/3 and What happens next 0/3 are proportions, with a real bar. Checklist 0 counts up over a hatched bar — this checklist was never told how many items to expect, so there is a number but no proportion to draw. The rest are hatched with no number at all.
What the bar looks likeWhat it means
HatchedNothing here is counted. Notes, photos, the cover, the plans card
A bar, with 2/6Two of the six questions on that card are answered
A number over a hatched barAn item checklist that was never told how many items to expect. It counts up and claims no total
An amber !2Two required questions are still open. Stated, never enforced
3

Capture without going anywhere

Two buttons float in the bottom-right corner of every site page: Photo and Note. They are there wherever you have scrolled to, and they are the fastest way in — you do not need to find the right card first.

The floating Photo and Note buttons in the bottom-right corner of the site page
Photo goes straight to the camera. Note opens the composer. Both land in this site, on the cards you would expect.
4

Write a note — and notice there is no Save

The composer is a box for what you saw, a place to say where, and buttons to attach a photograph. Underneath the buttons is the sentence that explains the whole app's save model.

The note composer, empty, with the placeholder What did you see? A note doesn't need a photo, a location box placeholdered Where? (optional) — e.g. riser cupboard, level 3, Add photo and Attach existing buttons, and Discard and Close
An empty composer says “Saved as soon as you write something or add a photo.” Nothing exists yet, and the app does not pretend otherwise.
The note composer with text typed into it, the line now reading Saved as you type, and the Site notes card heading showing a count of 1
Type one word and the line changes to “Saved as you type.” The note is already in the file. The card heading has already counted it.

So what do the two buttons do?

Close puts the composer away and leaves the note where it is — it is not a Save, because the saving already happened. Discard is a real deletion of the note you just wrote, with an Undo. If you opened the composer and typed nothing, closing it leaves no record at all.

The one gap in “saved as you type”

A note is only minted once it holds words or a photograph. Filling in only the location box — the one placeholdered Where? (optional), which carries no label of its own — or only answering a question the template added to the note, leaves nothing to save, and the line above the buttons still says “Saved as soon as you write something or add a photo” rather than claiming otherwise. Write the words too.

5

Photos

Photos taken from the floating button, or from the Site photos card, land in the site's own gallery. Each one gets a number, a date, and three things you can do to it.

The Site photos card with two photo tiles, each numbered, with an Add a caption button and mark-up and delete icons, and the date added
Tap the picture to open it full screen — double-tap or pinch to zoom, drag to pan. Add a caption writes the line that prints beside it. The pen icon opens the mark-up tools; the drawing is kept separately, so the original photograph is never written over.
6

Name it on the cover page

Cover page & site detailsOpen. Two boxes: the site name and the address. They are what identifies the site on screen, in every exported file's name, and on the front of the report.

The Cover page screen: a Site name box, an Address box, and a live preview of the report's front page showing SITE REPORT, New building and the prepared date
The preview on the right is the actual front page. It is honest about what is missing: with no account name filled in it says “No name is on this report — it goes out with no author.”

An empty address is a real answer

The app says so: “A site with no address prints no line rather than a blank one — leaving this empty is a real answer.” Type one and the map plate on the cover follows from it.

Below the cover boxes is Site details — questions asked once about this site. A template that asks nothing about the site says so plainly rather than showing an empty box.

7

Plans and drawings

Four ways into a measured sheet, and you pick whichever one the building gave you.

The Plans and export card offering four doors: Draw from scratch, Photograph a plan, Import a file and Capture a map, closing with the line Reading a CAD file costs nothing — import is free on every tier. Writing a drawing back out as DXF is a Pro feature.
Capture a map needs a connection once — after that the sheet measures at real-world scale offline forever. Import a file reads images, PDFs and DXF. A site assumes one level (Ground Floor) until you say otherwise, under Set upLevels.

Reading a drawing is free. Writing one out is not.

The card says it in one line: “Reading a CAD file costs nothing — import is free on every tier. Writing a drawing back out as DXF is a Pro feature.”

This card has one more button in the shipped app than in the picture

The screenshot above comes from the build the rest of this guide is photographed in, and that build names the export button Export drawing. In CoreProof Field the same button reads Back up this site, and two more sit beside it: Save the report (PDF), and — once a sheet actually holds drawn linework — Export DXF, which is visible on Free but greyed out. The reason sits in the button's tooltip, so on a tablet — where nothing hovers — a Free user sees the refusal without being told why.

8

Change its shape whenever you like

Set up at the top of the site page opens this site's own copy of its template. Five tabs — Template · What you ask · Arrange · What you hand over · Levels — and everything in them belongs to this site alone. The middle three are the template editor's own stages (Part 2), wearing the same names.

The Set up this site panel with five tabs: Template, What you ask, Arrange, What you hand over and Levels, showing the template picker
The Template tab exists only here: switch this site to a different shape, or save what this site has become as a template for next time. Picking another card reveals a confirm button that names it — Use “Inspection register”.

Switching can never lose an answer

The panel promises it in its own words: “Switching adds the new template's structure. It cannot delete an answer you have already given — anything the new one does not ask is kept, shown and still printed.” The same goes for the whole panel: “Nothing here can delete an answer somebody already gave.”

This is also the easiest way to make your first template. Set one site up until it is right, then use Save as a template at the foot of the Template tab. It saves structure only — no answers, no photos, no site name — and it is far less abstract than building one from an empty page.

9

An item checklist, if you are checking a list of things

An item checklist is the same questions asked of every door, room or unit, in reference order — on the printed report the section is headed “register”, which is the paper's word for it. It arrives with a template that has one, or you add one from Set upWhat you askAdd a sectionAsked of every item — and a site can hold as many checklists as the work needs.

The Item checklist card with a Set up button, a Record the next item button, a count of 0 recorded, and a line saying there is no expected total
Record the next item adds a row. No expected total is the honest default: the checklist counts what you record and claims no denominator until you tell it how many there are, under its own Set up.
10

Guided mode, one card at a time

A template can ask to be walked rather than scrolled. When it does, the progress strip grows a text button on its right: Guide me. Tap it and the page shows one card, with Back and Next and a Step 3 of 7 line between them.

The site page in guided mode: only one card is shown, with Back, Step 1 of 7 and Next above it, and All cards on the progress strip
Guided mode. The button now reads All cards — one tap and you are back on the whole page. It is a preference, never a gate: Next validates nothing, so you can walk past anything and come back.

Where the preference is set

Set upArrangeGuide this survey card by card. That checkbox is on this site's own copy; tick the same box in a template and every site made from it starts guided. None of the three templates that ship with the app declares it, so you will not see Guide me until you turn it on.

11

Sign it off on the device

At the foot of the page is Declaration & sign-off. Type who is signing, sign in the box with a finger or a stylus, and the app stamps the moment. The report prints all three — the signature, the name and the time — instead of the ruled blank line it prints when nothing has been signed.

The signer does not have to be you. The name is typed at signing rather than read from your account, because the tablet gets handed to a building manager or a client's representative, and their signature should not arrive under your name.

The Declaration and sign-off card: the declaration wording, a Signer's name box holding D. Whitlock Building Manager, a signature drawn in the box labelled Sign in the box, and a live Sign button beside Clear
The declaration's own words sit above the box, and here a name and a signature are both in. Sign only goes live once both are there — until then it is greyed, and its tooltip says why.
The same card after signing: the drawn signature replayed above a rule, the typed name, the line Signed 2 Sep 2026 with a time, and a Re-sign link
Signed. If the site's record changes afterwards the signature is marked as made before those changes and offered a Re-signnothing is ever blocked, and no edit is refused because somebody signed.

Where the block comes from

The shape that ships — Just start — declares one signature block, so every new site has this card. A template you write declares its own: the builder's Add a signature block is on the What you ask stage, and a template with none prints ruled blanks for a hand instead.

12

Finish, and hand it over

Finish, top right of the site page, opens a small card rather than leaving. It describes itself accurately: “Saves the report (PDF) and hands it to you to share, and quietly backs this site up in the same act.”

The Finish this site card: a list of amber pre-flight facts, a rename offer, and the buttons Save and share report and Just leave
Two buttons. Save & share report writes the PDF and hands it to the device's share sheet, falling back to your downloads. Just leave is the old Done. The X in the corner is Keep working.

The glance above the buttons

The amber list is a pre-flight glance: facts read off measures the page already has, listed only when they are not zero. A clean site gets no list at all — not a list of noughts. There are four possible lines:

  • N required questions unanswered — the same count the progress meter's amber numbers add up to.
  • N of M expected checklist items not recorded — only when somebody authored an expected total. No total, no line.
  • N sheets uncalibrated — a sheet built on an image that was never given a scale.
  • N photos cannot be read and will be left out of the report — checked before the report is built, not after.

None of it is a lock

The last line of the list says so: “Facts, not locks — the report prints what is here and says what is not.” Save & share report is never disabled by anything on that list.

What that one tap actually writes

The report (PDF) is the thing you hand over. Beside it, in the same act, the app writes a .coreproof backup of the whole site to your downloads — sheets, scale, photos, notes, answers. If that backup cannot be written the report still stands, and the card says so in one line rather than throwing the finish away.

On a Pro licence there is a third file: the survey package, a zip of the photos and the plans. If it fails, the report and the backup are unaffected — the card tells you and nothing is lost. On Free the card carries one quiet line instead: “The full package (photos + plans) is a Pro export.”

Nothing was hanging on this button

The card's own last line: “Everything you recorded is already saved on this device — the report is just the way to hand it over.” Finishing is not the moment your work becomes safe. It became safe as you typed it.

Part 2

Build a template


A template is worth building once you find yourself asking the same questions on every job. This builds one from the wizard, which is how every new template starts, and then walks the editor's four numbered stages.

1

Open Templates

Second stop on the left rail.

The Templates screen showing three saved example templates — Site walk, Inspection register and Plan and proposal — each with Edit, Duplicate, Rename, Export and Delete
A new device already has three templates on it — the worked examples. They are yours: edit, duplicate, rename or delete them freely. Deleting is permanent, so duplicate before you experiment. The small grey chips are what tells them apart — 2 sections · 6 questions, Opens on Arrival photos.

Three sections down this screen:

  • Your templates — the shelf. Each card has Edit, Duplicate, Rename, Export and Delete.
  • From a file — import a .coreproof-template somebody sent you. Free on every tier.
  • Note types — the labels a note can carry. Either each template brings its own, or you keep one list for the whole device.
2

Name it — step 1 of 3

New template opens a three-step wizard, in a panel above the shelf. The first step is only a name.

Step 1 of 3 of the new template wizard, asking for a name, with the Next button greyed out
Next is dead until you type something — that is the only thing it is waiting for. The name is how you find this shape in the picker every time you start a site.

Names must be unique

A name already in use is refused rather than quietly numbered, and the refusal appears in red under the step. Only the Duplicate button on the shelf adds “(copy)” for you.

3

Pick starting sections — step 2 of 3

Eleven ready-made sections, each a tappable card, grouped the way a real visit runs: Getting there, Doing the work, Wrapping up. Pick any number of them, or none. Nothing is pre-selected, because picking is the step.

Step 2 of 3: eleven ready-made section cards under three moment headings — Getting there, Doing the work, Wrapping up — each card with a scope chip, and a card at the bottom reading I'll write my own
The wizard's own warning is the important line: these are “starting points, not requirements”. Nothing here knows what your job needs. Rename, rewrite or throw any of them away once the template exists, and nothing links back.

Read the grey chip on each card

It is the single most consequential thing on this screen, and it decides the mechanism rather than the wording.

Asked once — this visit / this site

Two chips, one mechanism. It becomes a section — its own card on the site page and its own part of the report.

Every item

The same questions asked of every door, room or unit. It becomes an item checklist — the wizard's own line says it: “Every item rows create an item checklist: the same questions asked of every door, room or unit.”

The last card, I'll write my own, takes nothing and skips straight to step 3. It is the empty start, offered out loud rather than implied by picking nothing. And once you have saved sections of your own (step 12 below), they appear here too, under My sections, wearing a Saved by you chip.

4

What prints — step 3 of 3

A short checklist of the PDF's sections, one row per thing you picked, all ticked to begin with.

Step 3 of 3: a checklist of report sections — Cover page, the picked section, Notes and photos, Sheets and drawings — all ticked, and a Create template button
The panel is honest that this is a starting position: “Starts with these — change any of it later”, on the template's own Arrange stage. And: “A section with nothing in it prints nothing, so a tick never adds an empty page.”
5

Meet the editor: four numbered stages

Two columns: you build on the left, and the right-hand Preview shows what a site made from this template will look like. It follows every keystroke. Across the top sits the editor's spine — 1 · Name it · 2 · What you ask · 3 · Arrange · 4 · What you hand over — and the numbers are the order the work reads in, not a gate: move freely, in any order.

The template editor: the template name with Try it and Done top right, a numbered stage strip reading 1 Name it, 2 What you ask, 3 Arrange, 4 What you hand over, the sections list on the left and the live preview on the right
The editor opens on 2 · What you ask — the stage where sections and questions are written. Everything that stage holds is on one screen: the list, the ready-made shelf, the signature blocks and the labels, with the preview alongside.

There is no Save button, and that is correct

Every change is saved the moment you make it. Done just closes the editor, and Try it (step 13) opens a rehearsal.

Editing this cannot reach a site you already made

The line under the name says it: “A template on this device — every site already made from it keeps its own copy.” Sites take a copy when they are made; the shape on the shelf reaches only the next one.

6

One list, and “Asked of what?”

Everything this template asks lives in one list on the What-you-ask stage: your sections, any item checklists, and two fixed rows that are always there — Site details (the building's own facts, asked once, printed under the cover) and Note questions (asked under the words of every note somebody writes). Each row opens with its own Edit; one row is open at a time.

Add a section sits at the foot of the list, and the row it opens asks one question before it asks for a name.

The Add a section row, with a fieldset headed ASKED OF WHAT? offering three radio buttons — Asked once for this site, Asked of every item (door, room, unit…), and Asked on every note — and a Name box with an Add section button
Three answers, three mechanisms. Asked once for this site mints a section. Asked of every item creates an item checklist (step 11). Asked on every note opens the one Note questions row — those questions live in one place, so this door takes you there instead of minting a second copy.

Below your own rows sits Ready-made sections (11) — the same eleven from the wizard, each with a plain Add button — and, once you have saved any, My sections, your own shelf (step 12). The disclosure opens itself while a template has no sections and folds away once it has one.

7

Add a question: a family, then the exact answer

Type the question, then say how it is answered. The answer types are four familiesWords · Choice · Number · Photo / Date — and a family that could mean two things opens a second row of chips underneath to pick the exact one.

A question typed into a box with an Answered with row of four family chips — Words, Choice, Number, Photo / Date — Choice selected, and a second row of chips beneath it reading Yes / No, Pass / Fail, One of a list, Any of a list
Tapping Words or Number arms Add at once — a one-line answer, a plain figure — with the rest of the family on the second row if you want them. Choice and Photo / Date genuinely fork, so Add waits until you pick which; the line under the chips says what it is waiting for.
Both columns of the editor: on the left the new question Is the roof anchor point certified? sitting as the last row of the Getting in section with a PASS / FAIL chip and move, edit and delete controls; on the right the preview, whose Getting in card now lists it
Added, and in the preview immediately — the Getting in card on the right has already grown a line for it. Each question's own row carries move up, move down, edit and delete.

Edit on a question's row opens its panel. On a Pass / Fail question, one button does the thing most people want — “On a bad answer, ask for a photo and what's wrong” — two follow-up questions, shown only when a failing answer is given. Everything deeper sits behind More settings: a helper line for whoever is on site, a Required toggle, which answers count as good or bad, and Only ask this when… — a condition that keeps the question out of the way until a particular answer is given.

8

The preview, and its three faces

The pane on the right has three buttons of its own — On site, The report, Outputs — and they work from whichever stage you happen to be authoring in. Adding a question in What you ask and wanting to see what it did to the report does not mean walking to Arrange and back.

The preview pane's own three buttons, reading On site, The report and Outputs, with On site selected
Three faces, one pane. What you pick stays picked while you work — changing stage does not move it.
The preview showing the on-site face: the cards a site made from this template would have, in order, each listing its questions
On site — the cards, in order, with each question and how it is answered. The panel is clear that this is a shape and not a survey: “How a site made from this template will look, as you change it. Nothing here exists yet.”
The preview showing the report face: the PDF's sections in print order
The report — the PDF's sections in print order. A section with nothing in it prints nothing, so an empty-looking preview is not a fault.
9

Arrange: one list, two switches per row

Writing a section and placing it are two different jobs. The Arrange stage is one list of everything this template holds, and each row carries two pills: On site — does this card appear on the page — and In the report — does this section print. Move up and move down set both orders at once.

The Arrange stage: a checkbox reading Guide this survey card by card, then one list of rows with move up and move down, most carrying toggle pills reading On site and In the report; the Plans and export row shows On site — always, and the preview beside the list shows the report's print order
Switching a pill off never deletes anything — the intro line says it: “Switching one off never deletes anything.” One row cannot be hidden: Plans & export reads On site — always, because the site's backup lives on that card. The checkbox at the top is where guided mode is turned on.

A section switched off both ways is nowhere

Off On site and off In the report: nothing will ever ask it and nothing will print it. It is kept exactly as you wrote it, and its row on the What-you-ask stage says “Nowhere yet” — but it is easy to do by accident while tidying the order.

10

What you hand over

The fourth stage decides what Finish writes on a site made from this template. Each deliverable has a row with a tick — the report, the photo pack, the floor plan pack, the site's notes, and the materials schedule — and More settings on a row folds out its detail, including a file-name box that takes tokens like {site} and {date}. Under the rows, two switches say what prints beneath each photograph in the report: the GPS coordinates and the time & date.

The What-you-hand-over stage: ticked rows for The report, Photo pack and Floor plan pack and an unticked Notes row, each with a More settings fold, then an Under each photo block with GPS coordinates and Time and date ticked, and the preview beside them listing the files
Each row explains itself. What is ticked here is what the Finish sheet offers — the shape decides the deliverables, the site decides the content. The site’s .coreproof backup is not a row: Finish always writes it.

The photo pack has two sizes, and they are independent. Resized for handover caps each photo at 2,560 px — small enough to email — and Full resolution hands over the originals. Tick both and the package carries both, in folders that name them.

The photo pack's two tickboxes: Resized for handover, each photo capped at 2,560 px, and Full resolution, every photograph at the size it was captured, in its own folder — both ticked
Both ticked: the client gets images that fit in an inbox and the archive keeps the originals. Untick both and the pack produces no photographs — the panel says so in amber rather than leaving you to find out at Finish.

The materials schedule is off unless you tick it. A site that declares it grows a card reading everything on its drawings back — every block, opening and wall counted, split into Existing, Proposed and Demolition — which you can correct on site before it goes out. It hands over as a CSV, because a take-off is something you open in a spreadsheet.

The preview's Outputs face listing the deliverables this template produces, each with a line saying what it holds, including the photo pack line reading Both sizes
The Outputs face of the preview reads the same declaration the Finish flow will. The photo-pack line states which sizes in words — “Both sizes: resized for handover, and the captured originals in their own folder.”
11

An item checklist, if you are checking a list of things

The same questions asked of every door, room or unit, each answer set wearing its own reference — that is an item checklist. (On the printed report the section is headed “register”, which is the paper's word for the same thing.) It is made from the same Add a section door: answer Asked of every item and the checklist appears in the list, with its own row open and one question to answer first.

The Item checklist row freshly opened: a box labelled What are you inspecting? holding Item, and under it the line Rows will be numbered IT-001, IT-002… with a Change control
What are you inspecting? is the whole setup — one word, singular, and it is what the card and the report will call a row. The line under it reads back the consequence: “Rows will be numbered IT-001, IT-002…”
The same row after typing Door: the heading reads Door checklist and the line now reads Rows will be numbered DR-001, DR-002…
Type Door and the reference prefix follows the noun — DR — with the sentence re-reading itself before anything is committed. Change pins a prefix of your own, and from then on the noun stops touching it; blank it and the rows are a plain numbered list — 001, 002, 003.

Under the noun, Asked of every door is the same question builder a section uses. A template can hold as many checklists as the work needs — doors and fire dampers each get their own — and each numbers its own series. How many items are expected is deliberately not here: that is a count somebody takes in a particular building, so it lives on the checklist card's own Set up on the site, not in the shape.

Labels — and saving a section for next time

At the foot of the What-you-ask stage sits Labels: what notes and photos can be tagged as. Note types group the notes in the report; photo categories colour a photo's pin on the plan.

The Labels area: a Note types disclosure and a Photo categories disclosure, with a line explaining that types group the notes in the report and categories colour a photo's pin on the plan
An empty note-types list is a real answer — a note is then just a note, and the report does not group by one. The three photo categories every template starts with can be rewritten here.

Save a section to My sections

Every section row carries Save to My sections — your own shelf on this device. A saved section is then offered wherever the ready-mades are: the wizard's step 2 and the editor's shelf, wearing a Saved by you chip. On Free the shelf keeps three; Pro removes the cap, and everything already on the shelf still places.

Try it, then press Done

Try it, top right beside Done, opens a rehearsal: a real site made from this template — the same cards, the same report — that is nobody's work.

A rehearsal site made from the Roof inspection template: an amber strip across the top reading A rehearsal — try anything; nothing here is kept, and no site is created, with an End rehearsal button, above the site's own cards
The amber strip is the whole contract: “A rehearsal — try anything; nothing here is kept, and no site is created.” The page is titled Rehearsal — Roof inspection, and the checklist card already says Door — the shape you just built, live.

A rehearsal appears on no list and spends nothing against the Free plan's site cap. End rehearsal removes it and puts you back in the editor; close the app mid-rehearsal and it is swept away on the next start. Nothing a rehearsal touches can become anyone's work.

There is nothing to save. Done takes you back to the shelf, where your template is now waiting in every site's Set up from here on.

Written on this device. Export hands it to a colleague as a .coreproof-template file — they import it under From a file.

Export is the one Pro button on this screen

The button is there on every tier and never disappears — on Free, tapping it explains that “Exporting a template as a file is part of CoreProof Field Pro” instead of writing the file. Everything else here — writing templates, editing them, importing one somebody sent you — is free.

Part 3 · Blocks

A block is a symbol you drop onto a drawing — a WC, a bench, a switchboard. The app ships a catalogue of them, and you can draw your own. Blocks on the rail is where you look at both.

1

The catalogue

Every symbol the app can draw, each at its real proportions with its real size in millimetres. There is a search box across the top and a row of categories under it. This screen is readable with no site open — it is a reference, and finding out what exists should not require starting a survey.

The Blocks screen: a search box, category chips reading All 38, Anything, Sanitary, Kitchen, Furniture, Services and External, and a grid of blocks each drawn as its own symbol with its name and size
It opens on All 38 — every block there is, not a category. Each card carries the symbol as it will actually draw, its name, and its size — the star files it under your favourites, which is what the drawing palette offers first.
The block grid narrowed to the Sanitary category, showing WC, basin, bath and shower with their symbols and sizes
A category narrows it. Searching does the same across both the shipped catalogue and your own blocks at once, because “do I already have one of these?” is a single question.

Nothing is placed from here

A block goes onto a sheet, at the size that sheet's scale gives it — and there is no sheet on this screen. You place blocks from the drawing editor, on a site. This is the catalogue you consult, not the palette you draw from.

2

Draw one of your own

New block opens a drawing surface. Give it a name, set how big it is in millimetres, pick a category, and draw with the two tools: Box and Line. Drag on the square; everything snaps to 25 mm, so the numbers you read back are the numbers you meant.

The block editor: a Name box reading Reception desk, Width 1800 and Depth 800 boxes, category pills with Furniture selected, Box and Line tools with Undo and Clear, and a drawing surface showing a rectangle with a vertical divider inside a dashed footprint
The dashed rectangle is the block's footprint — the extent every sheet scales it by. It is not a shape you drew and cannot be deleted; the solid lines are yours.

Save it and it lands on My blocks, with its own symbol, its size and the shelf you filed it on. The pencil on a row opens the same editor again — a block you saved months ago can be corrected rather than deleted and redrawn.

The My blocks card showing the saved Reception desk with its drawn symbol, the size 1800 by 800 mm and the category Furniture, with edit and delete buttons
Yours, on this device. Deleting one here leaves every drawing that already carries it untouched — a placed block keeps its own geometry, so it travels in the file whether or not this shelf still holds it.

You can also save one from a drawing

If you have already drawn something on a site's sheet, select it in the drawing editor and save it as a block from there. Same shelf, same result — this screen is the way to make one without a survey open.

The 11 answer types

Four families on the row — Words, Choice, Number, Photo / Date — and eleven answer types inside them. All eleven do the same job wherever a question is written — in a section, on the cover, on a note, or on an item checklist.

TypeFamilyWhat the person on site doesReach for it when
Short textWords — the one tapTypes one lineA location, a make, a name
PhotoPhoto / DateTakes a pictureThe answer is the evidence

Pass / FailChoicePicks Pass / Fail / N/AAnything the defect schedule should read. Arrives ready to use

MeasurementNumberTypes a lengthAnything measured. Stored in millimetres, shown in the device's units
DatePhoto / DatePicks a dayAn install date, a last-serviced date
CalculationNumberNothing — it works itself outA figure derived from other answers. Never typed into

Four of them can control another question

Only ask this when… (behind a question's More settings) needs an answer it can match exactly, so it is offered over the four types that come from a declared list — One of a list, Any of a list, Pass / Fail and Yes / No — the whole Choice family. A condition over free text would need you to type the exact words you are matching, and one typo makes it permanently false.

Free and Pro

Every core tool is on the free app. What Pro adds is about what leaves the device, plus how many sites you keep active at once.

What the free app marks

Two marks, and both are on the deliverable rather than on your work. A footer pill reading Created with CoreProof Field · coreproofai.com, sized to its own text and tucked into the bottom-right corner so it never covers a title block or a scale bar. And a light diagonal CoreProof Field across the page — deliberately faint and sparse, two or three instances on a big sheet rather than a repeating carpet, and light enough that a 1px black line crossing it stays unambiguous. Pro removes both.

The 5-site cap is a soft one

It counts active sites. Archive one and its slot frees up; the archived site stays on the device, stays readable and stays exportable. Importing a .coreproof backup is never refused by the cap — the import lands and the archive choice is offered straight after. Work is never held hostage.

There is no cloud backup yet

Finish writes files to your device. Nothing is uploaded anywhere, on any tier. The wiring for a Pro cloud copy exists in the app and is switched off — it has no destination to send anything to — so the only copies of a site are the ones on this device and the files you exported. Keep the .coreproof files Finish gives you.

What catches people out

Six things, in the order you are likely to hit them.

  1. A hatched bar is not an empty bar. It means that card has nothing to count — no notes target, no photo target. It is not work you have failed to do. See Part 1, step 2.
  2. The location line only saves a note if you also write something. A note is minted by words or a photograph. Typing only into the box placeholdered Where? (optional) leaves nothing behind. See Part 1, step 4.
  3. Your device is not empty to begin with. Three example templates are put there at first launch. Duplicate one before you experiment — deleting them is permanent.
  4. “Asked of what?” is a mechanism question, not a wording one. Asked once for this site makes a section — answered once. Asked of every item makes an item checklist — the same questions repeated for every door, room or unit. Pick the wrong one and the shape is wrong, however good the wording. See Part 2, step 6.
  5. Writing a section is not the same as placing it. Switch it off both On site and In the report under Arrange and nothing asks it and nothing prints it — the row says “Nowhere yet”, but it is easy to do while tidying.
  6. Finish is not what makes your work safe. Everything is written as you type it. Finish is how you hand it over — and how you get a .coreproof backup file, which is the only copy that exists off this device.

One more, and it is quiet

Every template change saves as you type — but if a change is ever refused, the only sign is a single line of red text near the control that refused it. If something feels wrong, look just above and below what you were editing.
