Description:Pressure Altimeter is a precise altimeter and barometer app for navigation and weather-aware outdoor activities. It measures pressure altitude in real time by fusing your device’s barometer with GPS for stable, accurate readings, even offline. Ideal for hiking, climbing, trail running, cycling, backcountry skiing, and pilot ground training.
Key features include one-tap calibration using local weather station sea-level pressure or manual QNH entry, GPS and barometer fusion with drift correction, and real-time altitude, vertical speed, and pressure trend graphs with logging and export. Benefits include fast and reliable readings, a clear and customizable dashboard, low power usage, and convenient home or lock screen widgets. Keywords: altimeter app, barometer, GPS altitude, pressure altitude, hiking navigation, aviation QNH, weather pressure.
How to use:1. Install and open Pressure Altimeter, then allow location access and sensor permissions so the app can read GPS and barometer data.
2. Calibrate by selecting Auto to use a nearby weather station or enter sea-level pressure QNH manually, then choose units in feet or meters.
3. In Settings, select your data source and smoothing level to balance responsiveness and stability based on your activity.
4. Use the dashboard to monitor altitude, vertical speed, and pressure; start a log to record a session and add waypoints or notes as needed.
5. Add the home or lock screen widget for quick checks, and recalibrate when the weather changes or when you move to a new location for best accuracy.
