High-accuracy GNSS data displayed in real-time
RTK GNSS performance shown live in the app
Values depend on your receiver and correction source.
Set accuracy limits, required or recommended
Set your quality bar — the Fix type, the accuracy, the satellite count you need. FastXY monitors every shot and reports the moment a shot falls short. Undesirable points never get saved, so clean data comes back from the field — no matter who collected it.
- You set the bar: None, Warn, or Required
- Required means mandatory
- Live green/yellow/red for instant user feedback
GIS, Construction, Engineering workflows
From real-time field collection to post-processed static sessions — all in one app.

Built to work where the signal doesn’t
Collection, storage and maps all keep working with no connection — because the app was designed offline-first
On-device database
Every point, line, polygon and GNSS observation is stored on the mobile device the instant you capture it. Lose signal? Close the app? — your work is already saved.
Downloadable basemaps
Choose an area and download the map before you leave. Pan, zoom, collect and stake against real basemaps and 3D terrain with no connectivity
Crash-safe capture
If a session is interrupted, FastXY recovers your unrecorded data when you re-open the app — a closed app doesn't lose data
Positions keep logging with no connectivity
Extensive GNSS Metadata to prove the accuracy of your data
The entire coordinate stack, on-device
Fits the way you already work
