Made for iPhone & iPad
Know your position.
Keep the journey.
A clear view of your coordinates, a record of your route, and a place for the points worth keeping. Native on iPhone and iPad.
No account. Records stay on your device.
A field notebook, with the details.
From a fresh fix to a saved record.
Read the position
See system-reported coordinates, altitude, speed and accuracy. Open the details to understand each reading and its source.
Record the route
Start, pause and resume a track. Review the map, elevation profile and available three-dimensional geometry in your library.
Keep the context
Save a waypoint, add a note or attach a selected photo. Export your track as GPX, GeoJSON or CSV when you choose.
Tools
A common language for your coordinates.
Switch between familiar geographic formats and projected grids. Keep WGS84 originals while changing the way they are displayed.
Privacy
Keep the record close.
Tracks, notes and selected photo copies live on your device. GPSDeck has no accounts, advertising or analytics. Maps use Apple services; you control exports and sharing.
Position
Know what a reading means.
Every number has a source. GPSDeck separates system positioning, sensor readings and calculated results, and leaves unavailable values blank.
| Reading | Source & limits |
|---|---|
| Position & accuracy | Apple’s fused location result. Reported accuracy is not a guarantee of field error. |
| Motion & pressure | Live device sensors, where supported. Shown in the foreground; not stored in tracks. |
| Distance & coordinates | Calculated from saved locations using WGS84. Display precision does not increase measurement accuracy. |
| Satellites used in a fix | Not provided by the built-in receiver’s public APIs. No invented satellite counts or signal bars. |
