Scrivn Scan · tester guide

Measure a room by tapping its corners

Scrivn Scan turns your Android phone into a measuring tool. Stand in the middle of a room, tap each corner, and it draws the floor plan with every wall, door, window and cabinet on it. It maps wet walls and floors as you go. The outside of the house is measured in Scrivn, from photos. Thank you for testing it. This page shows how it works, what gets the best numbers, and how to send us a scan that came out wrong. That last part is what helps us most.

The short version

  1. Install the test version from scrivn.ca/scan-download (Before you start).
  2. Turn the room's lights on. Press Start, then hold the phone up and walk a few steps until the ring turns green.
  3. Stand near the middle of the room. Aim the ring at each corner, 6 to 8 ft away, and tap the screen. Go round the room.
  4. Tap corner 1 again to close the room. Then tap each door, window and opening at its two sides. Wet walls? Wet line is on the first row now.
  5. Open the plan (the little map, top right). Tape at least one wall in every room, the longest, then tap its length and type what your tape says. Share sends the plan as a PDF and a JPG, to scale.
  6. Next room: Add room, tap its corners, tap the doorway you came through, then More… → Join this room to another. Another floor: hold Add room.
  7. Outside: that's Scrivn, not Scan. In the claim, Exterior → From photos, and Scrivn walks you round the house a step at a time: the front, each corner at 45°, each side straight on, a measurement or two. Then Send to Scrivn team to measure (Outside of the house: from photos).
  8. Anything wrong? On the plan, tap Report a problem and tell us. Did the room twice? Report after the second run; both come along.

Before you start

Installing the test version

Scan isn't on Google Play yet, so testers install it from our site.

  1. On your phone, open scrivn.ca/scan-download, or point the phone's camera at this code. It downloads the newest test version.
  2. Open the downloaded file. Android asks whether your browser may install apps: allow it, go back, and tap Install.
  3. If Google Play Protect says it doesn't recognise the app or its developer, tap More details, then Install anyway. That's because it isn't from the Play Store yet.
  4. To update, open the same link and install over the top. Nothing you've set is lost.

When Scan is on Google Play you may need to uninstall this test copy before installing that one.

  • Your phone. An Android phone that runs Google's ARCore with its depth camera feature. Most recent Samsung Galaxy S and Google Pixel phones do. We test on a Galaxy S25 Ultra. If yours can't, the app says This phone does not support the ARCore Depth API. Please tell us which phone it was. There is no iPhone version yet: Android comes first.
  • First open. Allow the camera (it is how Scan measures) and let Android install or update Google Play Services for AR if it asks.
  • No account needed. Scan works on its own: the plan is on the Review screen, and Share sends it as a PDF and a JPG. Signing in to a Scrivn account, to send rooms into a claim, is optional (Your account and free scans).
  • No signal needed to measure. Everything you tap stays on the phone. Only sending, signing in and reporting need a connection (No signal).
  • Lights on, phone charged. Dim rooms measure short (more on that in the tips), and the camera works hard. If the phone gets too warm it says Phone is hot — let it cool before scanning.
  • Help in the app. The ? chip explains whichever chip is lit. More… → How to use this app has every step with a drawing, and Walk me through a room guides you through your first room.

The capture screen

The capture screen, drawn. The numbers match the list.
  1. Stop finishes the capture. After it the bottom row reads Start · Share · Send. A long press on Share saves the capture's files for us; you won't need it. When you're not capturing, Account sits in Stop's place.
  2. The mini-map. Your plan so far, with you on it. Tap it (or swipe up) to open Review, the full plan.
  3. The ring. What you aim with. A tap anywhere on the camera picture measures whatever is in the ring. Its colour says whether a tap will read (next section).
  4. The line. One line that says what just happened and what to do next, for example Corner 2 · wall 1: 12'6". When in doubt, read the line.
  5. The chips. What your next tap is. The first row: Corner, Door, Opening, Window, Closet (a closet door), and Wet line once the room is closed. The second row: Cabinet ▾, Fixture ▾, Ceiling, Stairs and More… for the rest. The lit chip is green.
  6. Undo takes back the last tap, so use it freely. ? explains the lit chip. Add room starts the next room in the same capture; hold it for another floor. Once a room is closed, Moisture joins this row, and on a walk-through capture 360° too.

The ring

The ring is the one thing to watch. Its colour tells you whether a tap will read:

  • Green: tap. The phone knows where it is and can see what's in the ring. A tap that reads gives a small buzz.
  • Amber, “sway”. The depth camera needs you to move. Take a step sideways, then tap. Amber with hold on… means the map is checking itself; give it a second.
  • Red, “tracking…”. The phone has lost the room. Taps are ignored until it finds it again (When tracking drops).
  • Grey. Before Start and after Stop. Nothing is measured.

Measure a room

  1. Press Start. It asks what you are capturing: Sketch only, or Sketch + walk-through if you also want 360° photos of the rooms. The outside of the house is done in Scrivn (Outside of the house: from photos).
  2. Hold the phone up and walk a few steps around the room, not on the spot, until the ring turns green. When you start a new room the line says Room 2 · look round it slowly first. Do that too.
  3. Stand near the middle and stay there. You don't walk to the corners; you tap them from where you stand. 6 to 8 ft away reads best. If you're too close, the line says Step back — corners read best from 6–8 ft.
  4. Aim the ring at the corner, where the two walls meet, at about chest height, and tap. Then the next corner, going round the room one way. The line gives each wall as it goes: Corner 2 · wall 1: 12'6".
  5. Back at the first corner, tap it again. That closes the room: Room closed · W × D · N corners — openings or wet lines next, or Add room. The chip moves to Door for you.

A closet or small room against walls you've already tapped? Just tap its own corners. Once they close it off, Scan takes the rest from the walls already there.

Walk a few steps with the phone up until the ring is green.
Stand in the middle, tap every corner from there, then corner 1 again.

Doors, windows and openings

  • Door, Opening (a doorway with no door) and Closet (a closet door) are two taps: its left jamb, then its right jamb. Keep the ring on the frame, not the gap. Aim a hand-width onto the wall beside it. The line confirms the width: Door 1 · 2'8".
  • Window is two taps on the outside of the casing: the bottom of its left edge, then the top of its right edge. Those two taps give the width, the sill and the head.
  • The chip stays lit after an opening, so you can go straight on to the next one.
  • What kind of door: swing, bifold, pocket or sliding, and which way it opens, is set on Review by tapping the door's width (Review: check it, tape it).
  • Closets: tap a closet's door with Closet, not Door. Before Send or Share, Scan asks about each closet door (Review: check it, tape it).
An opening is its two jambs.

Cabinets, tubs and appliances

  • Press Cabinet ▾ and pick Base (lower), Upper or Full height. Each run is two taps, one at each end. Aim at the wall above it or at the face of the cabinet, whichever you can see.
  • At an inside corner, tap each run as far as you can see it and stop. The corner cabinet fills itself in. A gap wider than a cabinet is read as an appliance (a fridge, a dishwasher) and left alone.
  • A run out in the floor is an island. It asks for a third tap on its back edge, which gives its depth.
  • Fixture ▾ has Tub, Shower, Fridge / freezer and Range, each tapped the same way: at its two ends. A tub that nearly fills its alcove is stretched to fit it.
A run on the wall is two taps; an island is two, then its back edge.

Stairs, ceilings and the awkward bits

Stairs and Ceiling are on the second row; the rest are on More…. Each has its own drawing in the app (tap ? once it is lit).

Stairs

Four taps round the flight like a rectangle: both ends of the near riser, then the far riser, starting on the same side. The line at the end says which way it read the flight. Check it before moving on.

Ceiling

Aim at the ceiling and tap, then tap once more to check it. A flat ceiling: the second tap on the same spot - the two reads should agree. For a slope or a vault, tap the high side, then where the ceiling meets the wall at its low side. You can also set it on Review.

Can't reach

For a corner you can't see. Tap the wall leading into it twice, at least 3 ft apart, then the wall leading out of it twice. The corner is worked out where the two walls cross.

Open span

Where the floor stops and there is no wall, like the top of a stair between half walls. Two taps, one at each end, in place of two corners.

Wall end

The free end of a thin partition: one tap on its end. It's the hardest tap in the app. If it won't come in straight after a try or two, leave it out.

Corner unit

A fireplace or pantry built across a corner with short returns: four taps (wall, front, front, wall). A plain angled corner needs nothing special: just two corner taps.

Finish this room (on More…) closes a room where you stand. Use it when the last wall is one you can't tap, or when a closet's other walls are already there.

More than one room

  1. In the room you're finishing, tap the doorway into the next room (Door or Opening, both jambs).
  2. Walk through with the phone up and press Add room. Its text turns green when the room you're in is closed. Look round the new room slowly first, then tap its corners from its middle.
  3. Tap the same doorway from this side, both jambs. Then More… → Join this room to another. The plan zooms to the two doorways, marked here and there; press Join here. If it picked the wrong pair, Another doorway shows the next one.

Join every room at its doorway. Joining lays the room exactly against its neighbour. It's also what puts a room back in place after tracking drops. Undo right after a join takes it back.

Forgot a doorway in the room you left? Open Review and hold your finger on that wall: it offers Door, Opening or Closet door there, and the join comes up with it. To go back and add to an earlier room, tap its name on Review (during a capture).

Each room taps its own side of the doorway they share; the join lays them together there.

More than one floor

A basement, a main floor and an upstairs go in one capture, a level each. Hold your finger on Add room:

  • New level above or New level below starts a level. It asks for a name (e.g. Second floor, e.g. Basement) and, the first time, the name of the level you are on now (e.g. Main floor). Press Start it, go to that floor, and tap its first room as you would any room.
  • Each level is a plan of its own: its rooms are tapped fresh and joined to each other, not to the floor above or below. You don't need to line the floors up at the stairs.
  • Back to a level returns to it; Rename changes a level's name. Review shows the rooms of the level you are on.
  • Share makes a plan page for each level. Send sends each level into the claim as its own storey: it asks Which storey is Main floor? for the level you started on, and places the others above or below it.

Moisture as you go

Optional, for water jobs: the wet walls, floor and ceiling of each room, marked while you stand in it. Scrivn turns them into the claim's moisture map.

Wet walls: Wet line

  1. Once a room is closed, Wet line appears at the end of the first row. Press it: Wet line · tap the top of the wet line at one end of a wet stretch.
  2. Aim the ring at the top of the wet line, as high as the meter finds it wet, at one end of the wet stretch, and tap. Then the same at its other end. Round a corner, tap one end on each wall.
  3. Scan lays it on that wall, in whichever room it is, and reads how high it is wet. A box asks what the wall is (Drywall, Wood framing, Paneling or Concrete), the Meter reading (optional), and the height, which you can type over. Undo last there takes the line back.
  4. The chip stays lit for the next wet line.

Floors, ceilings and the job: Moisture

Moisture on the bottom row swaps the chips for Wet line, Floor, Ceiling, Setup and Done.

  • Floor and Ceiling open the plan to paint the current room: Paint the wet floor of Laundry with a finger - two fingers move the plan. Drag a finger where it is wet. Whole room fills it (then Clear room empties it), Erase then a drag takes paint off, Undo last takes back the last stroke, and Done goes back to the camera.
  • Setup takes the dry reference (a reading of the same material where it did not get wet, one per material), the water class, which dehumidifiers you use (LGR or desiccant, and their size), and the room's wall insets over 18".
  • Done goes back to the room chips. You can come back to Moisture whenever a room is closed.

Review then draws the air movers and dehumidifiers the drying plan calls for, and says what they come to: Drying: 2 air movers · 1 LGR dehumidifier (medium) · Class 2. It is the same drying calculation Scrivn uses. Send carries the wet lines, readings, painted areas and setup into the claim.

A room on Review: a wet line round a corner, the wet floor painted, and the equipment it calls for.
The app's own drawing: tap the top of the wet line at each end of the stretch.

When tracking drops

The phone keeps track of where it is by what it sees. Bare walls, dark stairwells, doorways and fast turns can make it lose the room: the ring turns red and the line says Finding the room again — hold the phone up.

  • Stop walking. Hold the phone up and turn slowly, looking at the parts of the room you've already tapped: corners, furniture, doorways. Not the ceiling, not a bare wall.
  • When it's back it may ask for one corner again: Tap corner 3 again — ringed in orange on the map. Aim at that corner and tap it. That ties the map back together: Back on the map — carry on.
  • Lengths it isn't sure of yet read checking… on the plan until a tap or a join settles them.
  • Still off? More… → Re-find me on the map asks for two or three corners you tapped before and moves the sketch to match.
  • If one spot keeps dropping, it has nothing to track. Work from where you can see more of the room. If a room is hopeless, finish what you can, Add room, and do the rest as a second room. Two rooms you can trust beat one you can't.
After a drop: the corner to tap again is ringed in orange.
Stop, turn slowly, show it what it has seen before.

Review: check it, tape it

Review: a typed length shows the phone's reading struck through.

Tap the mini-map to open Review, during a capture or after Stop. It's the whole plan, drawn to scale.

  • Best practice: tape at least one wall in every room. The longest one is best. It checks the phone's reading against a real measurement and sets the plan's scale. Two walls in a dim room. Until a room has one, the line under the plan reminds you: Tape one wall for true sizes — tap its longest wall's length, type your tape, tick Scale the whole room.
  • Every length is a button. Tap it and type what your tape says (8'3, 99" or 8.25). The room resizes around it. The phone's reading stays visible, struck through. Reset tape takes typed lengths off again.
  • Scale the whole room to this wall. Tick it when you type a tape length and every wall in the room scales by the same amount. It suits a room that reads short all round (see the tips).
  • Tap a door's width to say what kind of door it is: Swing, Bifold, Pocket or Sliding, Single or Double, and for a swing door Opens in or Opens out and Hinge on the other side. The tape for its width is in the same box. A door left alone goes over as a swing door, a closet door as a bifold, and anything 3'6" or wider as a pair. Setting it in one room sets the same doorway in the room next door.
  • Name the room and set its ceiling with the two buttons under the plan. Flat, sloped or vaulted.
  • Hold a wall to put a door, opening or closet door on it.
  • Pinch to zoom, drag to move, double-tap to fit it back. Undo last takes back the last thing you did.
  • Share (here, or on the bottom row after Stop) makes a PDF and a JPG of the plan, to scale, walls drawn 4" thick: the whole plan with every wall's length and a 10 ft scale bar, then each room's size, floor area, perimeter, ceiling and wall area, doors, windows and cabinets. It asks about closets first, as Send does. Add a job name or address if you like. Both are saved to Download/Scrivn Scan and the share sheet opens, so you can email them, print them or put them in Drive. No account needed. The PDF prints to scale at 100% (not fit to page); the JPG can be an underlay in Xactimate, set to scale off its 10 ft bar or any wall you taped.
A door's width tapped on Review: what kind of door, which way it opens, and its tape.

The closets step

When you press Send or Share, Review shows each closet door in turn with a dashed Closet? box behind it. Tap the box if there's a closet there and it's drawn in; leave it if not. Next closet moves on and the last one reads Send (or Share). A closet bigger than the box? Back, then tap it as a room of its own and join it at its door.

The closets step: tap the dashed box to draw the closet in.

360° photos

Start with Sketch + walk-through to take 360° photos. They are a step of their own at the end, after the sketch and the moisture: the camera stops tracking the rooms while you take them, so do your tapping first.

  1. Once a room is closed, 360° is on the bottom row. Press it. Review opens, titled Tap where you're standing.
  2. Stand where you want the 360 and tap that spot on the plan. The wide camera takes over the screen; hold still while it sets up (360° – hold still a moment).
  3. Hold the phone at chest height and turn slowly on the spot. Hold the ring on the amber dot until its arc fills and it turns into a green tick. Then the next dot. There are 12 round the room at eye level, then 6 on the floor: tilt down when the line says so.
  4. After each 360 the plan comes back: walk to the next spot and tap where you are standing. Press Done when you have them all: 360s done - 3 taken. Keep tapping, or Stop.

The first time, a card explains the step. If the phone lost its bearing (the app was left and came back), the line says The phone lost its bearing - walk a few steps, then 360 again.

The 360 step: tap the plan where you stand.
Then turn on the spot; hold the ring on each amber dot until it fills.

Outside of the house: from photos

The outside isn't measured in Scan. It's done in Scrivn, from photos taken with the phone's own camera, on any phone, iPhone too. Scrivn walks you round the house one step at a time: the front, then each corner and each side, a photo at each and a measurement where you have one. Then send it to the Scrivn team, or measure it yourself.

Round the house, in any order

  1. Outside of the house, then From photos. On the claim, Outside of the house opens the sketch straight on its Exterior; then From photos. The Exterior report (PDF) sits right under it once the outside is measured.
  2. Say the corners. The list starts with the front. Under it, + Outside corner, + Inside corner or + Joins the neighbour adds the next corner round and the wall after it: corner 1 is the front's right-hand end, then on round with the house on your left. Say them as you come to them, or all at once. Take back undoes the last. The house's shape comes from them: nothing to draw.
  3. Photos, any order. Tap any wall or corner in the list to put photos on it: every wall straight on, every outside corner at 45° stepped back until three corners are in, more than one where a wall is long or broken up (above or below a deck is fine: Take more of this wall). A tight side yard: the phone upright, on the 1x lens. Each ticks off as its photos come in; an inside corner needs none.
  4. Add a measurement, any time: which wall, what (Garage door with 9′/16′, Window, Door, Wall), its size in feet, inches and an eighth, and Photo of the tape on it if you can: close up, the number and both ends of the tape. At least one for scale, ideally one a wall. Nothing is drawn on the phone.
  5. Finish whenever you're done. What's still missing is said above it (walls or corners with no photo, no measurement, corners that don't close round to the front), never forced. Back to the walk opens it again.
  6. Send to Scrivn team to measure, at the end. That's all a tester needs to do: we place each measurement on its photo exactly. Or Measure it here: see below.

Every step is saved as you take it, on the phone first: no signal is fine, and a walk half done picks up where you left it. Back a step and Take it again are on every step. Add photos my own way leaves the walk for the old way (draw the shape, add photos, tap corners); Back to the step-by-step walk returns to it.

Where to stand, seen from above: the front and each wall straight on, every outside corner at 45°.

Good photos

  • Sideways, on the 1x lens. The normal camera, held landscape. Not the wide lens, and no zoom. Upright only for a side too tight to step back from.
  • The 45° photos matter most. Step back far enough for three corners: the one you're at and the far end of each wall. They hold the measurement together, the back corners and the ones behind a porch or deck too. A photo that shows just one corner of the house helps much less.
  • Each gable square-on, the peak and both slopes of the roof edge in it.
  • Door heights are not a good ruler. Doors vary too much. Use a tape or the garage door.
  • One tape front to back, if you have a long one: the long side wall, front corner to back corner, at the ground. Put it in as that side's measurement: Wall.

Measuring it yourself

Easiest on a computer or a tablet: the photos are small on a phone.

  1. Place the measurements. Each one typed on the walk is listed with Place it: drag its line across it on its photo, end to end (the ring is where you tapped at the house). A wall's length is already its side's, once the walk is round.
  2. Tap the corners. Measure it here opens each photo of the walk in turn, with what to tap: on a corner's photo, the corner where it meets the ground and the far end of each wall if you can see it; on a side's, its two corners. Scrivn numbers them from what each photo was taken for. Tap a number to change it. Next photo goes on round.
  3. Measure. Measure the house gives each side's length and how sure it is (±). Scrivn then marks more corners, dashed, where the measure puts them. Tap a wrong one to take it away or renumber it. Looks right keeps the rest and measures again.
  4. Check these. Only what the photos couldn't show for sure: is that tall glass a window or a door? How far does the garage roof sit under the house's? One tap each. Looks right closes it, and anything left stays as read.
  5. The roof check, on Plan & roof. The roof is drawn from the shape and the photos. Press only what is wrong: Gable or Hip at an end, + Porch roof, + Cross gable. Then Looks right. The pitch says assumed, 4/12, until you type it.
  6. The report. Each side opens face-on with its photo behind it, for its windows, doors and siding. Exterior report (PDF) on the claim: the four elevations, the roof plan, the photos and every measurement. Stucco trim (surrounds, keystones, columns) is counted apart from the field stucco.
On a photo: the corners tapped at the ground, and a line across the garage door.
After Measure: each side with its ±, and the wall a tape would fix.

Send to Scrivn team to measure

  • At the end of the walk (or beside Measure), Send to Scrivn team to measure. Add a note if you like (e.g. the side yard is too tight for a photo), then Send.
  • We measure it from that claim's outside photos, measurements and note, and see nothing else. Meanwhile the Exterior says Sent to the Scrivn team – it'll show here when it's measured. Photos still on the phone go when there's signal. Withdraw takes it back.
  • When it's done you get an email; its link opens the claim on the outside, which says Measured – Use it. A wall none of your photos faced asks first: no photo of this wall. Any windows or doors on it? None, or how many of each. Nothing else is asked: what the photos show is ours to read. Use it puts our measurements in, with what you said. Your photos and measurements stay. A wall still unanswered is drawn and reported Not photographed, never as a bare wall; you can answer on the wall itself later.

A shed or a garage

+ Add building at the top of the Exterior, then Shed, Detached garage or Workshop (or type a name). For a simple building, Quick box: its two lengths, the wall height, the roof, the siding, its doors and windows. Or From photos: the same walk round it. Each building gets its own pages in the report.

Townhouses and semis

Nothing to pick first. At the corner where your home meets the neighbour's, tap Joins the neighbour: Scrivn takes the home as a semi (one such corner) or a middle townhouse (two). No 45° there: take the front at an angle from that end instead, the whole front in. The shared wall is skipped, not photographed or counted; at its far end, the back at an angle the same way. A middle unit ends with two angled photos of the front and two of the back. Measuring it yourself, Where this home ends: tap where this home ends at the ground, often a downspout, a trim line or where the colour changes.

Your account and free scans

Account is at the top left whenever you're not capturing. You don't need an account to measure or to share a plan.

  • Not signed in, it offers Sign in (your Scrivn email and password), Create an account, Pair with a code from Scrivn and Delete an account.
  • Accounts are by invitation for now. Create an account says Accounts are by invitation until Scrivn opens sign-up to everyone. If you've been given an account, sign in; to ask for one, write to us at scrivn.ca/contact.
  • Signed in, it shows your name and company, your email, your scans this month, and Scans you send go into this account's claims in Scrivn. Sign out stops this phone sending to the account; scans already sent stay there.
  • Delete account asks for your password. It deletes your sign-in and details and signs the phone out. If nobody else is in your company's account, its claims, scans and photos are deleted too, and any plan is cancelled. It can't be undone. Scan still works without an account afterwards. You can also delete it at scrivn.ca/account/delete.

Free scans

  • A scan is one capture: everything from Start to the next Start, all its rooms and levels.
  • It counts once, the first time it leaves the phone: sent to Scrivn or shared. Sending it again, or sharing it after sending it, doesn't count again. A phone with no account isn't counted at all.
  • A Scrivn account with no plan has 3 a month. Any Scrivn plan, or the Scan plan, is unlimited.
  • While Scan is in testing nothing is refused: scans are counted, and Account says Unlimited scans while Scrivn Scan is in testing (2 scans this month).
Account, not signed in.

Sending to Scrivn (optional)

If you have a Scrivn account, Scan sends rooms straight into a claim.

  1. Sign in once. Account → Sign in, with your Scrivn email and password (Your account and free scans). Or pair instead: in Scrivn, open your Account page and press Pair a phone, then on the phone tap Account → Pair with a code from Scrivn → Scan code and point it at the QR code (or Type code for the eight letters). Until then the Send button reads Sign in.
  2. After a capture, press Stop, then Send. Pick the claim (or New claim) and the storey.
  3. The rooms go over with their names, ceilings, doors (and their kind), windows, cabinets and fixtures; the wet lines, readings and painted floors and ceilings; every level as its own storey; and the walk's 360° photos for a walk-through capture.
  4. Open in Scrivn takes you to the claim's sketch. Scrivn may offer to fill in closets and spaces between rooms that weren't tapped.
  5. No signal? Send anyway: it waits on the phone and goes by itself (No signal).
Sign in or pair once, then pick the claim.

No signal

Basements and rural jobs often have one bar or none. Both apps keep working.

In Scan

  • Measuring needs no signal. Rooms, levels, moisture, 360s, Review and the tape all work on the phone alone.
  • Share works too. Signed in, it is counted when the signal is back.
  • Send lists the claims the phone last saw (Send to which claim? (no signal – the list from …)), or New claim. Then: No signal – the scan and its photos are saved on this phone and go to Scrivn on their own when there is signal. Keep working, or close the app: it is not lost.
  • Over the buttons it says 1 scan waiting to send – it goes on its own when there is signal. Tap it to see what is waiting, or Send now. Pressing Start or closing the app doesn't lose it.
  • Signing in, creating an account and Report a problem need a connection; a report that can't go offers Try again.

In Scrivn

  • Claims you've opened on the device open without signal, and new ones can be started. Everything saves on the device and syncs on its own when the signal is back. The header says Offline and how much is waiting.
  • The sketch, the moisture map, the drying log and the exterior all work offline. Photos are kept on the device and upload by themselves.
  • From photos measures on the device, so the outside needs no signal either. Send to Scrivn team to measure waits for signal and goes by itself.
  • Reading the walkthrough, generating the documents and AI trace wait for signal, then run by themselves. Reading a meter's screen from a photo needs signal: type the number instead.
  • If the same claim was changed somewhere else in the meantime, Scrivn keeps both and asks which you want.

Tips that make the numbers right

These come from walking real houses with the app. Each one fixed something we saw go wrong.

Always tape at least one wall

Best practice in every room: tape the longest wall and type it in on Review. It checks the phone against a real measurement and sets the plan's scale. In a dim room tape two. If every wall reads short by about the same, tick Scale the whole room to this wall.

Turn the lights on

In dim rooms the walls read short, by 2% to 7% (a 12 ft wall coming in 3 to 10 in short). Doors and windows read true either way. If a room is dim the line says Room's dim — turn the lights on for truer lengths.

Mind mirrors and glass

The depth camera can't read a mirror or glass, and a big mirror can throw the phone off its place. Tap corners from where the mirror is out of view; for a corner in or behind one, use Can't reach on the walls either side.

Aim where the corner is clear

A sofa, a TV or a shelf in front of the corner makes it read short. Aim above or below the clutter, wherever you can see the crease where the walls meet.

Stay in the middle

Tap every corner from one spot near the middle, 6 to 8 ft away. Walking to each corner and tapping it close up is slower and reads worse.

Move slowly, keep it pointed at things

Turn slowly and walk through doorways looking ahead, not at the floor or a bare wall. Most tracking drops are a fast turn or a blank view.

Doorways from both sides

Tap every shared doorway in both rooms and join the room there. It's the one thing that lines the rooms up exactly, even after a drop.

Check Review before you leave

A quick look at the plan in the room catches a wrong corner while you can still tap it again. Undo is always safe.

Big closets are rooms

A walk-in or anything bigger than the dashed box: tap it as its own room and join it at its closet door.

Outside: the corners at 45°

The photo of each outside corner, both walls in, is what ties one wall to the next: the back corners too. Skip them and the depth comes out short. Then tape the long side wall front to back, and any wall Scrivn flags (Outside of the house: from photos).

Send us a scan that went wrong

This is the most useful thing you can do as a tester. Every fix so far started with a scan like yours and its log, which is the app's own record of what it saw and decided, tap by tap.

  1. Open Review (tap the mini-map) and tap Report a problem at the top right. During a capture, More… → Send this scan to the Scrivn team does the same.
  2. Say what went wrong: which room, which wall or corner, what you expected, and the tape measurement if you have one. “Bedroom 2, wall 3 came in 6 in short, tape says 11'2” tells us exactly where to look.
  3. Add your name or email if you'd like us to reply. Then Send.
Did the room more than once? Report after the last run. The scan on the screen goes, and so does the app's recent log, with every run before it since the app was opened.

What's sent: the scan's measurements, the app's recent log (this run and any others since the app was opened), your phone's model and Android version, and what you write. No photos. It works with or without a Scrivn account, but it needs an internet connection; if it can't send, it says so and offers Try again.

Something that isn't about a scan (the app crashed, a button doesn't make sense)? Report it the same way; a note with no scan is fine.

Report a problem: a note, and how to reach you if you'd like a reply.

Rough edges we know about

  • Thin partition ends (Wall end) are hard to hit cleanly from across a room. If one won't come in, leave it out.
  • Corners behind furniture and dim rooms read short. Tape a wall (see the tips).
  • Dark stairwells and long bare hallways are where tracking drops most.
  • Stop finishes the capture. After it the chip bar and More… are gone, and Start begins a new, empty capture. Look over Review before you press Stop; a missed doorway can still go on afterwards with a long press on Review.
  • A wet line can't be changed after its box is closed. Undo it and tap it again.
  • The outside from photos is new. If a wall comes out wrong, tell us which and what your tape says, or send it to the Scrivn team to measure.
