TERRA on the phone
Ask the land while standing on it.
The same engine, in your pocket, with the things only a phone can do: the GPS, the camera, and a memory that works without signal. Free. No store, no account.

What the phone adds
- Read where you stand
- One tap on the land under your feet. The engine reads the square kilometre around you from orbit and hands back a verdict with its evidence.
- Walk the boundary
- Mark each corner with the GPS, or let the track follow your steps. Close the loop and the parcel is read as you walked it, area and perimeter included.
- Field notes with the camera
- A photo taken in place, with where it was taken and which way you faced, saved beside the reading. What the satellite cannot see, you can.
- Works without signal
- Every reading you make stays on the phone and opens in the field. A boundary walked with no signal is kept and read when it returns.
The app is the website, installed: the same readings, the same wall, the same account. What it adds is the phone itself. Your readings and field notes live on the phone and, if you sign in, on your account.
