Features

Everything you need in the field β€” no accounts, no cloud, no mobile data.

  • Offline maps anywhere

    Download regions over Wi-Fi and use the map with no internet. Import ready-made maps: MBTiles, SAS.Planet, Locus, RMaps, JNX and KMZ.

  • Background track recording

    Walking, cycling, hiking β€” recording continues with the screen locked and the app minimized. An unfinished track is recovered after a crash.

  • Waypoints and collections

    Mark points with icons, colors and notes. Group them into collections and toggle layer visibility on the map.

  • Routes and areas

    Draw lines and polygons right on the map, drag vertices, measure area.

  • Sharing without internet

    Send collections, tracks and offline maps to another phone directly over Wi-Fi via a QR code β€” no accounts, no cloud.

  • Navigate to a waypoint

    A dashed line and voice guidance to the selected waypoint β€” audible even with the screen locked.

  • Ruler and coordinates

    Measure distance and bearing with two fingers. Search by place name and by coordinates (DD / DM / DMS).

  • Everything stays with you

    Data is stored on your device. No accounts, no cloud, no sharing with third parties.

How it works

  1. Prepare at home

  2. Work in the field

    Record a track, place waypoints, draw routes β€” with no network.

  3. Share on the spot

    Send data to teammates directly over Wi-Fi via a QR code.
