Record your hikes, drop waypoints, unlock achievements.\n\nThe app reads your device's raw GPS through Android's own LocationManager rather than going through Google Play Services. It contains no Google libraries at all, needs no account and no network connection: everything works fully offline, and every position, track and waypoint stays on your phone.\n\nREAL-TIME POSITION\nCoordinates in decimal degrees or DMS, geoid-corrected altitude using the EGM96 model, speed in km/h and m/s, horizontal and vertical accuracy with a colour indicator. You always know how much to trust your fix.\n\nFULL SATELLITE VIEW\nEvery visible satellite listed, constellation by constellation. An azimuth and elevation sky plot. And a custom-built 3D globe showing the real geometry of the constellation above you: you finally see where your GNSS signals are coming from.\n\nCOMPASS\nHeading dial referenced to magnetic or true north, your choice. Point-to-point navigation with arrow, distance and bearing to any waypoint you pick.\n\nTRACK RECORDING\nStart a session and put the phone back in your pocket. Distance covered, average and maximum speed, elevation gain and loss, minimum and maximum altitude.\n\nWAYPOINTS\nMark what matters (water source, campsite, trailhead, etc.) with customizable icons. Every waypoint stays linked to the session it was dropped in.\n\nTRIP LOG\nBrowse all your past sessions with elevation profile, route trace and full statistics. GPX export so you can open your tracks anywhere.\n\nACHIEVEMENTS AND LEVELS\nOver 25 achievements across families: altitude, from your first summit to Kilimanjaro. Speed. Simultaneous satellites. Total distance. Number of trips. Plus a few special ones: cross the 45th parallel north, get tracked on both sides of the equator, drop a waypoint before 6 a.m. Every achievement earns XP and level","categories":["Navigation","Sports & Health"]}
