Before you leave service, open Tools → Offline maps and grab a state or a custom-drawn area. Downloaded maps, search, and tap-to-identify all work in airplane mode.

Yes. Start recording and lock the phone — your track keeps recording in the background. If the phone dies or the app is closed mid-ride, the recording is recovered automatically the next time you open the app.

Say “Hey Siri, mark a waypoint in Trailmark ADV.” For screen-off background capture, turn on Settings → Siri & Voice → Hands-free background capture (it needs Always location).

Yes — open a GPX, GeoJSON, KML, or KMZ file into Trailmark (from Files, Messages, or another app) and review it before saving. Your data comes over with its colors, routes, and icons. You can also export your own data as GPX to share back. See the import guide.

Yes — a route can carry options: an out-and-back spur, or a fork with the technical line on one side and the bypass on the other. Add them while you're drawing the route with the branch button in the plan bar, or later from the route's OPTIONS card, then pick which ones you're riding on the day. Distance, climb and the fuel verdict recompose with every choice. See the route options guide.

Tools → Import & export → Export all data writes one backup file with every waypoint, track, trip, photo, and setting. On the new phone, import that file to restore it all. Re-importing the same backup is safe — it merges instead of making duplicates.

Settings → Units and Coordinates. Coordinates can be decimal, DMS, or UTM.
