GTL logs a GPS route on the phone. Every point stays on the device. Nothing is uploaded to our servers.

Tap Start to record and Stop to finish. Then share the track as KMZ for Google Earth, or as GPX 1.1 for OsmAnd, Komoot, Garmin Connect, QGIS, and similar apps. The app is in English and Hungarian.

Map
• Google Maps online, or an offline Mapsforge map you download: OpenStreetMap regions, or Turistautak for hiking in Hungary.
• A head-up display shows speed, accuracy, and satellites in use. While recording it also shows distance and elapsed time.
• Search places on the offline map. Type at least 3 characters. Up to five nearby names.
• Tap the map for a live straight-line distance to that point, or copy the GPS coordinate.

Recording
• Choose how you travel: motorbike (default), car, bicycle, run or hike, boat, or aircraft. Each choice sets units, filters, and how often a point is stored. Any setting can be changed afterwards.
• Units: metric, imperial, or ICAO (knots, nautical miles, feet).
• A point is stored only when accuracy and the satellite count are good enough. Optional smoothing tidies the stored line. Thinning the line on the map does not delete points from the saved file.
• In motorbike mode the phone can log lean angle. Fix it flat on the fuel tank.
• Barometric altitude when the phone has a pressure sensor, with QNH and optional calibration from GPS. Ambient temperature when that sensor exists.
• The screen can stay on while recording.

GPS, route, compass
• Live satellites: GPS L1 and L5, Galileo, GLONASS, BeiDou, QZSS, and NavIC, with signal quality and a sky plot.
• Latitude, longitude, accuracy, and altitude.
• Route totals: elapsed time, distance, time moving, time waiting, and an elevation profile. A dashed line shows barometric altitude when pressure samples exist.
• Compass: magnetic north, or true north from the last GPS fix. It works without recording.

Saved tracks
• Show a saved route on the map, open its elevation chart, or delete it.
• Share one track or several in a single KMZ or GPX file.
• In Google Earth, start, pause, and stop markers sit on the line. A tap shows time, altitude, and the session figures. Pause marks a standstill, not a separate button.
