Please include the GPSDeck version from Settings > About GPSDeck, your device model, iOS or iPadOS version, and the steps that led to the problem. Screenshots can help; remove private coordinates, route names, and photo details before sending them. Do not send passwords or an entire location archive unless specifically needed and you choose to do so.
Getting a location
Open Position and tap Enable location. Allow location access in the system prompt. For more useful measurements, enable Precise Location in Settings. Move to an open area and wait for a fresh sample. Record and Mark remain unavailable without a fresh valid location. Some iPad models and environments provide less precise or fewer measurements.
Recording a route
Tap Record, Pause to take a break, Resume to continue in a new segment, then the stop button and Finish and save. Saved tracks appear in Library. Active recording uses background location. Force-quitting, permission changes, or system interruption may leave gaps. GPSDeck recovers saved samples on relaunch and identifies interrupted tracks; it cannot recreate measurements it never received.
Waypoints and photos
Mark saves your current location. Edit lets you change the name, notes, and photo attachments. Changes take effect when you tap Save. Map > Pick on map saves a chosen 2D position with unknown height and accuracy. Compass guidance shows straight-line bearing and distance; it does not calculate a safe or passable route.
Missing readings
A dash or Unavailable means the measurement is absent or invalid. Enable motion and pressure separately in Motion & pressure. These readings are live foreground measurements and are not written to the track. Some devices lack a compass or pressure sensor. GPSDeck cannot read the built-in GNSS receiver's satellite list, signal strengths, or RTK status.
Export and deletion
Open a saved track, tap Export, choose GPX, GeoJSON, or CSV, then select the recipient in the system share sheet. GPX and GeoJSON include linked waypoints; CSV contains track samples. Photo attachments are not included.
Delete records in Library. Removing a track keeps saved waypoints and photos. Remove those separately if you want to erase them. Clear export copies in Settings > Storage. Shared files and backups must be deleted at their destination.
Measurement limits
Position and accuracy are system-reported fused results. Sensor availability, magnetic interference, pressure changes, and local conditions affect measurements. GPSDeck is not a certified safety or surveying instrument.
