Foreground recording only. We request that the screen stay awake where supported. Locking the phone or switching apps pauses recording; tap Resume afterward. Missing sections are not reconstructed. GPS points stay on this device. No turn-by-turn guidance, contours or offline street tiles. Trail lines © OpenStreetMap contributors, ODbL, snapshot October 2, 2026.
