Sign in or create your account
Sign in with Google, Apple, or an emailed code — no password to remember. Already signed in on your phone? Scan a code to sign in on a computer. The same account follows you across web, iPhone, and Android, every design auto-syncs, and Settings shows every signed-in device.
RoomSketch3D needs an account to save your designs and sync them between your computer, your phone, and your tablet. Setting one up is genuinely fast — most people are signed in in under ten seconds, and there's no password to remember after.
There are three ways in: Google, Apple, or an email code. Pick the one that matches the account you already use most — they all create the same RoomSketch3D account, and you can use a different method next time if you want.
Already using the RoomSketch3D app on your phone and want to carry on at a computer? You don't need to remember how you first signed up. Open app.roomsketch3d.com/link on the computer and scan the code it shows with the phone app. The computer opens your own account, with all your designs, without typing an email or a code. This also avoids the most common mix-up, a second empty account made by signing in a different way on the computer.
What you'll need
- •A Google or Apple account, or any email address you can check right now
Step by step
- 1
Open the sign-in page
On the web, click Sign In in the top-right corner (or just go to app.roomsketch3d.com directly — you'll be sent to the sign-in page if you're not already signed in). On iOS or Android, open the app — the sign-in screen is the first thing you see.
The sign-in page — three options, picked in the order most people prefer them. - 2
Continue with Google
The fastest path. Click Continue with Google, pick the Google account you want to use in the pop-up, and you're in. No password to type. If you've ever signed into a Google service in this browser, it's literally one click.
Continue with Google — one tap when you're already signed into a Google account in this browser. - 3
Continue with Apple
Same experience, with Apple instead. Click Continue with Apple, confirm in the Apple sign-in sheet, and choose whether to share your real email or use Apple's relay address. On iPhone and iPad, Touch ID or Face ID takes care of the confirmation step. Continue with Apple is on the web, iPhone and iPad. The Android app offers Google sign-in only.
Continue with Apple — supports Apple's Hide My Email relay if you'd rather not share your real address. - 4
Signed up on iPhone with Apple? Use Continue with Apple on the web too
If you first signed in on iPhone or iPad with Apple and chose Hide My Email, your account's email is an Apple relay address (…@privaterelay.appleid.com), not your real one. To reach that account on a computer, go to app.roomsketch3d.com and click Continue with Apple, then sign in with the same Apple ID. Your designs and your purchase are there. Don't type your real email into the email-code box. RoomSketch3D has never seen that address, so it makes a new, empty, unpaid account. Not sure which email your account uses? On the phone, open the avatar (top right) → Settings. The address under your name, at the top of the Account tab, is the account. (Or skip the question entirely: sign the computer in from the phone, below.)
On the web, Continue with Apple opens the same account you made on iPhone with Apple, including a Hide My Email one. - 5
Or, sign in with an email code
Prefer plain email? Type your address in the you@example.com field, click Email me a sign-in code, and check your inbox for a six-digit code. Type the code on the next screen and you're in. Nothing to remember; the code expires after about ten minutes. The code path is web-only — on iPhone and Android, the native Google and Apple buttons are simpler one-taps.
Email code — no password to remember; a fresh code is mailed to you each time. - 6
On a computer? Sign in with your phone instead
If you already use RoomSketch3D on your iPhone, iPad or Android phone, the easiest way onto a computer is to let the phone sign it in. On the computer, go to app.roomsketch3d.com/link, or open app.roomsketch3d.com and click Sign in with your phone at the bottom of the sign-in page. Nothing to type, and it's guaranteed to be the same account as your phone, so every design is there. The button only appears on computers and tablets. On a phone's own web browser there's nothing to link, so you sign in the usual way there. The whole flow, including what to do when a code won't scan, is in Sign in on a computer with your phone.
On a computer, Sign in with your phone takes you to the page that shows a code for your phone to scan. - 7
Leave the code on the computer screen
The computer shows a square code and, under it, a short eight-character code such as ZXTD-9HS7, with Waiting for your phone… below. Leave this page open while you pick up your phone. Each code works for five minutes. If it runs out before you scan it, the page puts up a fresh one by itself, so just scan the new one.
app.roomsketch3d.com/link: scan the square code, or type the short code under it. - 8
On your phone, open Settings ▸ Link a computer
Open the RoomSketch3D app, tap your avatar (top right), then Settings. On the Account tab, tap Link a computer. It's only in the iPhone, iPad and Android apps, since the phone's camera does the work.
Settings ▸ Account ▸ Link a computer, in the iPhone, iPad and Android apps. - 9
Scan the code
iPhone and iPad: the camera opens straight away, full screen. Point it at the code on the computer; it reads it by itself, with no button to press. The first time, allow camera access when asked. Android: tap Scan the code, choose Take Photo, and take a picture of the code on the computer screen. The app reads it from the photo. Camera not working, or no camera handy? Tap Type the code instead and enter the short code from the computer, with or without the dash. After ten wrong codes within 15 minutes, typing pauses until that window passes (scanning still works).
On iPhone and iPad the scanner opens by itself and reads the code as soon as it's in view. - 10
Check which computer is asking, then tap Sign in
Before anything happens, your phone shows which browser is asking, roughly where it is and its internet address, for example Chrome on Mac, near San José, United States. If that computer seems to be in a different country from your phone, the note turns red; that's the sign of a code someone relayed to you, so don't sign in. If it's the computer in front of you, tap Sign in. A moment later the computer opens RoomSketch3D, signed in to your account. If you don't recognise it, tap Don't sign in; the computer is told and nothing is signed in. Each code can be used once. Every computer signed in this way also gets you an email, in your app's language: A computer was signed in to your account, with the computer, the time, roughly where and its internet address. If it wasn't you, its Review signed-in devices button takes you straight to where you can sign it out.
The phone shows the browser and rough location of the computer before you approve it. - 11
See every signed-in device, and sign one out
In the app or on the web, open Settings ▸ Account ▸ Signed-in devices. It lists everywhere your account is signed in: the app or browser and system (for example Chrome on Mac), roughly where it was signed in and its internet address, and when it was last active. The device you're holding has a This device badge and no sign-out button, so you can't sign yourself out by accident; use Sign out in the account menu for that. Tap Sign out next to any other device, or Sign out of all other devices to sign out everywhere except where you are (it asks you to confirm first). A signed-out device is sent back to the sign-in page the next time it does anything. The refresh button at the top of the list picks up a device that just signed in. Devices signed in before this list existed show Location unknown.
Settings ▸ Account ▸ Signed-in devices: sign out one device, or all the others at once. - 12
You're done — designs sync automatically
After you sign in once on each device, every design you create or edit syncs in the background. Start a floor plan on your laptop, walk into the room with your phone, and the same plan is there waiting. No upload button, no manual import — it's automatic.
Tips
Pick the method that matches your real device
If you mostly use an iPhone, signing in with Apple ties your account to the same Apple ID you already unlock the phone with — fewer surprises later. If you live in Gmail / Google Calendar / Google Drive, pick Google. Email is the universal fallback.
It's the same account, whichever button you press
Sign in with Google today, switch to the email code tomorrow — they hit the same account as long as the email address matches. Different emails make different accounts, though, so be consistent.
There's no separate "sign up" step
First time you sign in, RoomSketch3D creates your account in the background. No email verification, no profile form. A few welcome pages then show finished rooms made in the app, followed by the unlock screen. See Your first sign-in.
Moving from phone to computer? Let the phone sign it in
If you started on your phone, use Sign in with your phone (or app.roomsketch3d.com/link) on the computer rather than guessing which button you used on the phone. The phone approves the computer into its own account, so you can't end up in a second, empty one, even if your account uses Apple's Hide My Email.
Sign out is in the account menu
Click the avatar (your initial, top right of Home or the editor) → Sign out. Signing out never deletes anything. You don't need to sign out to switch devices, because staying signed in everywhere is the point.
Common mistakes
Signing in with two different emails on two different devices
If you tap Google on your laptop and Apple on your phone with two different email addresses, you've made two separate accounts — and your designs won't sync between them. Pick one method (or one shared email address) and stick with it.
Letting Apple's Hide My Email confuse you later
When you use Continue with Apple, Apple can give the app a relay address like abc.def@privaterelay.appleid.com. That's the email RoomSketch3D sees. If you later sign in with the email code or Google using your real address, you create a new, empty account by mistake, and the purchase isn't on it. Keep using Continue with Apple to come back to the same account, on the web as well as on iPhone.
Approving a code someone else sent you
Only tap Sign in for a computer that's in front of you right now. Anyone who gets you to approve their code, for example by sending you a picture of it, would be signed in to your account and could open and change your designs. If you approved one by mistake, or get a “computer was signed in” email you don't recognise, go to Settings ▸ Account ▸ Signed-in devices and sign it out, then email roomsketch3d@immex.tech.
Searching the inbox for a forgotten password
There isn't one. RoomSketch3D never uses passwords — it's Google, Apple, or a fresh six-digit code emailed to you each time. If you can't sign in, the issue is usually the wrong email address, not a wrong password.
Frequently asked questions
Do I need a Google or Apple account?
No — the email-code option works with any email address. Google and Apple are just one-tap shortcuts; the underlying account is the same.
Why is there no password?
Passwords get phished and forgotten — RoomSketch3D skips them entirely. You either sign in via your existing Google / Apple account (which already has a password you're using), or via a fresh code emailed to you for each session.
Will my designs sync between my phone and my computer?
Yes — automatically. As long as you sign in with the same method (and therefore the same email) on each device, every design you create or edit shows up everywhere within seconds.
Can I change which method I use?
Yes, as long as the email address stays the same. The account is keyed to the email — switching from Google to email-code (or back) on the same address signs you into the same account.
What if I used Apple's Hide My Email and forgot the relay address?
Use Continue with Apple again. Apple identifies you with the same Apple ID each time, so you'll be back in the same account. You don't need to know the relay address. You can see it at the top of Settings in the app, and Apple lists the relay addresses it has made for you in your Apple ID settings under Hide My Email.
I signed in on my computer and my designs are gone, and it wants me to buy again. What happened?
You're in a second account. This almost always happens because you signed up on iPhone with Apple's Hide My Email and then used your real email on the computer. Sign out on the computer, then sign in at app.roomsketch3d.com with Continue with Apple (same Apple ID). Your designs and purchase are there. Nothing was lost. If you did work in the second account, see Designs missing after signing in for moving it across.
Can I sign in with Apple on Android?
No. The Android app signs in with Continue with Google only. If your account was created with Apple (including Hide My Email), use it on the web at app.roomsketch3d.com and on iPhone or iPad. If you can't get into your account on a device, email roomsketch3d@immex.tech with the email shown at the top of Settings.
Does RoomSketch3D cost anything to sign up?
Creating an account takes seconds. Designing in RoomSketch3D is a one-time purchase ($19.99, no subscription, no recurring fees) that unlocks everything on every device. Before you buy, you can take the Guided Tour: close the unlock screen and tap Take the Guided Tour to see the real editor on a sample plan.
Can I sign in on a computer without typing my email or a code?
Yes, with the phone app. On the computer, go to app.roomsketch3d.com/link (or click Sign in with your phone on the sign-in page). In the app, open Settings ▸ Account ▸ Link a computer, scan the code and tap Sign in. The computer is signed in to the same account as your phone.
Can I sign in on my phone's browser this way?
No. Linking signs in a computer or tablet from the phone app. On a phone's own browser (Safari or Chrome outside the app), the link page shows no code and offers Sign in on this phone instead, and the scanner only exists inside the RoomSketch3D app.
The code on the computer expired. What now?
Just scan the new one. Codes last five minutes, and the page replaces an expired code by itself. If the page says the sign-in was declined, click Show a new code.
My phone's camera won't read the code. Is there another way?
Type it. On the scanner, tap Type the code instead and enter the eight characters shown under the square code on the computer. On Android, if the photo isn't read, hold the phone steady, fill the frame with the code and try again.
How do I sign out of a computer I'm not at, or every other device?
Settings ▸ Account ▸ Signed-in devices. Tap Sign out next to the device, or Sign out of all other devices. The device is signed out the next time it does anything; it can't keep working in your account.
I bought on the web — how do I sign in on iPhone or Android?
Sign in to the same account, meaning the same email, that you used on the web. The purchase belongs to the account, so the app unlocks as soon as you're in. One purchase covers the web, iPhone, iPad and Android. If you still see the paywall, check the email at the top of Settings. If it's not the account you paid with, sign out and sign in the original way. (Already purchased? Restore access in the app only re-checks an Apple or Google purchase, so it won't find a web purchase.) If it is the right account and the app still asks you to buy, email roomsketch3d@immex.tech with that email.
