live capture and export
open the web viewerwhat comes out
Every scan exports four ways.
The geometry is the easy part. What usually gets stranded is everything around it: the measurements, the location, the notes and photos you took standing in the room. The app keeps all of it.
USDZ
3D mesh
For AR Quick Look on iOS and the web viewer. The same file opens on a desktop browser or in someone's hand.
Quantities report
Floor area, wall area, paint volume, and room count per project. The takeoff is already done by the time you stop scanning.
ZIP
Everything bundled
DXF, USDZ, report, photos, voice and text notes, and the GPS pin, in one archive ready to hand off.
the principle
Three things we will not change.
01
On-device
The capture and the exports run on your iPhone or iPad. Nothing leaves the device unless you send it.
02
No account
No sign-in, no email gate, no cloud project to manage. Open the app and scan.
03
No tier
Free, ad-free, and the same on day one as on day one hundred. The export is not the upsell.
view it anywhere
The viewer is a URL, not an install.
Drag a USDZ into usdz-viewer.lagarsoft.com and the floorplan renders in Three.js, with a reset view and a file switcher. No sign-in, nothing to install, works on desktop, tablet, or phone. Send the file to anyone and they open it the same way.
Getting a RoomPlan scan to render faithfully on the web is the hard part. We wrote up the converter behind it, USDZ to Three.js, matching iOS fidelity, in this post.
why free
This is not the business.
We build production-grade software for AEC, MEP, and real estate teams. That is the work. These are tools we needed and made open because the principle behind them is the one that runs through everything we do: you should be able to verify the work before you trust the people who made it. A tool that runs on-device and hands you everything makes that argument by itself.
We wrote up the launch in more detail on the blog: Scan it, own it: a free LiDAR scanner with no tiers.
