## Description

Altimeter Barometer — Turn your phone into a real air pressure meter and altimeter.<br><br>Read the actual atmospheric pressure from your phone&#39;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.<br><br>━━━━━━━━━━━━━━━━━━━━<br><br>Who it&#39;s for<br><br>• Hikers &amp; trekkers — track elevation as you climb<br>• Drone &amp; aviation hobbyists — check air pressure before flight<br>• Weather watchers — spot pressure trends that hint at incoming weather<br>• Campers &amp; anglers — monitor conditions outdoors<br><br>━━━━━━━━━━━━━━━━━━━━<br><br>Key features<br><br>[Real air pressure]<br>• Live reading from your phone&#39;s barometer sensor (not a fake estimate)<br>• Units: hPa, mbar, inHg, mmHg<br><br>[Altitude estimate]<br>• Calculated from measured pressure<br>• Adjustable sea-level pressure (QNH) for better accuracy<br>• Switch between meters and feet<br>• Note: pressure-based estimate — may differ from GPS altitude<br><br>[Pressure trend]<br>• See whether pressure is rising or falling<br>• Rising tends toward fair weather, falling toward clouds or rain (guide only)<br><br>[Records]<br>• Max / min / current pressure with one-tap reset<br><br>[Clean design]<br>• Material Design 3, light &amp; dark themes<br>• 37 languages supported<br><br>━━━━━━━━━━━━━━━━━━━━<br><br>⚠️ Requires a barometer sensor<br><br>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.<br><br>Download now and measure the air around you.
