Your space,
twinned.
Walk a building with your iPhone. Get a textured 3D model, an editable floor plan and a 360° walkthrough — processed on the phone, ready to plan on.

Multi-room capture
Scan. Twin. Plan.
One walk-through with your phone. Everything after that happens on the plan.
Scan
Walk each room with an iPhone or iPad Pro. Tap “Next room” and keep going: one capture, the whole floor.
Twin
The phone bakes a textured 3D mesh, a clean model and a to-scale plan. No upload needed to see it.
Plan
Open the plan, move walls, furnish, route electrical and plumbing. Edits show up in 3D straight away.
From raw scan to finished plan.
Every tool works on the same capture, so nothing gets re-drawn by hand.
A 2D/3D editor on top of the real scan
Edits are kept as a layer over the scan, so the original capture is never lost. Undo anything, and see every change in 3D.

Processed on the phone
The 3D model and plan are built on the iPhone itself. No waiting on a server.
Offline-first
Scan and edit with no signal on site. Everything syncs when you are back online.
Your workspace
Projects, scans and plans live in your organisation’s own workspace.
iPhone & iPad Pro
Needs a device with a LiDAR sensor (Pro models) on iOS 17 or later.
Which devices does Twynn work on? +
Scanning needs an iPhone Pro or iPad Pro with a LiDAR sensor, on iOS 17 or later.
How accurate are the measurements? +
LiDAR scans are accurate enough to plan furniture, layouts and services on. For anything that is cut or fabricated to fit, check the critical dimensions with a tape on site.
Can I scan more than one room? +
Yes. A single capture can cover several rooms: tap “Next room” as you walk, and Twynn keeps them on one plan.
Does it work without internet? +
Yes. Scanning, viewing and editing work offline. Your captures upload in the background once you are connected again.
What can I export? +
A USDZ or GLB 3D model, a PDF report of the plan, and an AR view you can place on any table.
I already have a floor-plan drawing. Can I use it? +
Yes. Upload the image, Twynn detects the walls, and you finish the trace. You can also draw a plan from scratch.
Your space, twinned.
Twynn for iPhone and iPad Pro is coming to the App Store.
