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.
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.
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
.coreproofbackup. - Account — the account you signed in with, and a Pro licence if you hold one.
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.
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.
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.
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.
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 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.
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.
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.
| What the bar looks like | What it means |
|---|---|
| Hatched | Nothing here is counted. Notes, photos, the cover, the plans card |
A bar, with 2/6 | Two of the six questions on that card are answered |
| A number over a hatched bar | An item checklist that was never told how many items to expect. It counts up and claims no total |
An amber !2 | Two required questions are still open. Stated, never enforced |
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.
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.
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.
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.
Name it on the cover page
Cover page & site details → Open. 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.
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.
Plans and drawings
Four ways into a measured sheet, and you pick whichever one the building gave you.
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.
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.
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.
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 up → What you ask → Add a section → Asked of every item — and a site can hold as many checklists as the work needs.
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.
Where the preference is set
Set up → Arrange → Guide 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.
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.
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.
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 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.
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.
Open Templates
Second stop on the left rail.
Three sections down this screen:
- Your templates — the shelf. Each card has Edit, Duplicate, Rename, Export and Delete.
- From a file — import a
.coreproof-templatesomebody 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Add a question: a family, then the exact answer
Type the question, then say how it is answered. The answer types are four families — Words · Choice · Number · Photo / Date — and a family that could mean two things opens a second row of chips underneath to pick the exact one.
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.
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.
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.
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.
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.
.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 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.
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.
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.
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 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.
.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.
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.
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.
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.
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.
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.
| Type | Family | What the person on site does | Reach for it when |
|---|---|---|---|
| Short text | Words — the one tap | Types one line | A location, a make, a name |
| Photo | Photo / Date | Takes a picture | The answer is the evidence |
| Yes / No | Choice | Taps a tick | A plain either-or, with no N/A |
| Pass / Fail | Choice | Picks Pass / Fail / N/A | Anything the defect schedule should read. Arrives ready to use |
| Number | Number — the one tap | Types a figure | A count or quantity. Give it a unit word — “each”, “m²” |
| Paragraph | Words | Types a few lines | An observation in their own words |
| One of a list | Choice | Picks a single answer | Your own fixed set. Arrives empty — you write the answers |
| Any of a list | Choice | Ticks as many as apply | Same, but more than one can be true |
| Measurement | Number | Types a length | Anything measured. Stored in millimetres, shown in the device's units |
| Date | Photo / Date | Picks a day | An install date, a last-serviced date |
| Calculation | Number | Nothing — it works itself out | A 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.
| Thing | Free | Pro |
|---|---|---|
| Capture — notes, photos, mark-up, item checklists, sheets | Everything | Everything |
| Writing and editing templates | Yes | Yes |
| Importing a plan — image, PDF, DXF | Free on every tier | Yes |
Importing a .coreproof-template | Free on every tier | Yes |
| Exporting a template as a file | No | Yes |
| The report (PDF) | Marked — see below | Unmarked |
The .coreproof backup written by Finish | Yes | Yes |
| The survey package (photos + plans, as a zip) | No | Yes |
| Writing a drawing out as DXF | No | Yes |
| Saved sections (My sections) | 3 | Uncapped |
| Saved blocks — your own drawn symbols (My blocks) | 3 | Uncapped |
| Active sites on a device | 5 | Uncapped |
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.
- 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.
- 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.
- 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.
- “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.
- 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.
-
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
.coreproofbackup 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.
Limits and file types
How much fits
| Thing | Limit | What happens at it |
|---|---|---|
| Active sites (Free) | 5 | Archive one to start another. Archived sites stay on the device and stay exportable |
| Templates on a device | 60 | Refused, with a message naming the number |
| Sections in a template | 40 | Refused |
| Questions in one section | 100 | Refused |
| Note types in a template | 200 | Refused |
| A template's name | 120 | The box stops accepting characters |
| A section's name | 60 | The box stops accepting characters |
The two file types
.coreproof
A whole site — sheets, scale, photos, notes, answers. Written by Finish, or by Back up this site on the plans card; restored from Settings. This is your backup and your way onto another device.
.coreproof-template
A shape only, no answers. Exported from a template card, imported under Templates › From a file. Importing is free on every tier; exporting is Pro.
