Altimeter Barometer
Measure real air pressure (hPa) and estimate altitude. For hiking & weather.
About Altimeter Barometer
Altimeter Barometer — Turn your phone into a real air pressure meter and altimeter.
Read the actual atmospheric pressure from your phone's built-in barometer sensor, then estimate your altitude using the international standard atmosphere formula. Perfect for hiking, trekking, drone flying, weather watching, camping, and fishing.

Key features
[Real air pressure]
• Live reading from your phone's barometer sensor (not a fake estimate)
• Units: hPa, mbar, inHg, mmHg
[Altitude estimate]
• Calculated from measured pressure
• Adjustable sea-level pressure (QNH) for better accuracy
• Switch between meters and feet
• Note: pressure-based estimate — may differ from GPS altitude
[Pressure trend]
• See whether pressure is rising or falling
• Rising tends toward fair weather, falling toward clouds or rain (guide only)

⚠️ Requires a barometer sensor
This app reads real atmospheric pressure, so it needs a device with a built-in barometer (pressure) sensor. Many mid-to-high-end phones include one, but some budget devices do not. If your device has no barometer, the app will tell you clearly instead of showing fake values.
