Altimeter Barometer & GPS

Precise altimeter with aviation dial, QNH calibration, and GPX track logging. Turn your smartphone into a professional navigation tool with an authentic aviation interface. Designed for hiking, mountaineering, tactical navigation, and off-grid survival. By hardware-linking barometer data with satellite navigation (GNSS), you receive highly accurate altitude readings anywhere in the world. Key Features • Smart Telemetry (BARO + GPS LINKED): Automatic correlation of atmospheric pressure shifts with satellite coordinates to filter out hardware errors and altitude spikes. • Aviation Dial: A classic multi-pointer cockpit instrument that is intuitively readable even in glaring sunlight or while on the move. • Professional Calibration (QNH): Manual adjustment of your base altitude using known topographic landmarks, local weather stations, or physical maps. • GPX Route Recording: Continuous background path logging with file export capabilities for overlaying your tracks onto topographic maps (including OSM). • Real-Time Elevation Profile: A dynamic visual chart tracking your ascent rate, maximum altitude, and minimum elevation. • Waypoint Manager: Save custom coordinates and control marks to your logbook without needing an internet connection. • Glance Widget: View critical telemetry metrics directly on your smartphone's home screen. • Unit Support: Instantly toggle between meters and feet with a single tap. Fully Offline & Autonomous Built for the field. All navigation logic and sensor calculations process locally on your device. Advanced power-saving algorithms automatically pause hardware polling and UI rendering when your screen is turned off. This allows you to maintain continuous GPX track recording in the background while preserving critical battery life for survival and extended outdoor use.
