• Unit support for pressure (mb, inHg, kPa, atm, Torr, psi, hPa, mmHg), altitude (meter, feet)
• Personalization graphic in analog classic style.
• Calibrate values output by sensors.
• Calibrate the app by GPS altitude, GPS location and nearest airport information/METAR, manuals enter QNH
• Pressure tracking and history graph.
• Notification about pressure change. Useful when you are in weather sensitive zone like desert, mountain, sea.
