How it works
Your room, on the phone in your hand
Open it in your browser
Safari on iPhone, Chrome on Android, no store, no download. Tap Share, then Add to Home Screen, and it opens full screen like an app.
Draw the walls or scan the room
Type in your real measurements, or sweep the room with your camera. Any phone works, no LiDAR needed, and you can capture without an account.
Furnish it and check the fit
Drag in real pieces from IKEA, CB2, Herman Miller and more, see them true to scale in 3D, and buy the ones you love from the retailer.
What a phone is good for
Scan on the phone, finish anywhere
The phone is the best place to capture a room, because the camera is already in your hand. Sweep the walls once and Cona rebuilds them as a 3D room you can correct and furnish. Building that scan into a room happens on our servers and asks you to sign in, so the finished room can reach the editor on any device.
Drawing and furnishing work on the phone too. If you would rather do the detailed work on a bigger screen, a free account carries the room from your phone to your laptop.
FAQ
Frequently asked questions
Is there a Cona app in the App Store or Google Play?+
No. Cona runs in the browser on iPhone and Android, so there is nothing to download. You can add it to your home screen from the browser's share menu and it opens full screen, like an app.
Does room scanning work on Android, or only on iPhone?+
Any phone with a camera. Scanning does not need LiDAR. You can capture the room without an account; building the scan into a 3D room and keeping it asks you to sign in.
Can I start on my phone and finish on my computer?+
Yes, with a free account. Without one your draft stays in the browser you used, and a copy is saved to Cona, but it will not appear on your other devices.
Is the phone version free?+
Yes. Designing and furnishing rooms is free on every device, with no credits, no watermarks and no trial that bills you later.
Does it work on a tablet?+
Yes. Any modern browser on a tablet, a phone or a computer works, and the same room opens on all of them once you have a free account.
