Turn your phone into a precise barometer. It reads the built-in pressure sensor directly — works fully offline, with charts, storm alerts and home-screen widgets.

Barometer+Pressure Tracker measures atmospheric pressure using your device's own barometer sensor, so readings reflect exactly where you are, not the nearest weather station. No connection is needed to measure.

✨ Key Features:
- Direct Sensor Readings — no internet, no weather-station estimates, just your phone's barometer, in 6 measurement units (hPa, mbar, mmHg, inHg, kPa, PSI)
- Smart Calibration — sensor adjustment for maximum accuracy
- Background Monitoring — continuous tracking with customizable intervals
- Storm Warnings — automatic alerts for sudden pressure changes
- Beautiful Charts — zoom from 6 hours to 30 days, plus a full-screen view
- Four Gauge Styles — classic, glow, digital, and realistic analog
- Home Screen Widgets — gauge, compact horizontal, and chart widgets with customizable colors
- Wear OS companion app — use a Wear OS device with a pressure sensor as a source of data
- Notifications — set up a notification when the threshold is breached or the trend changes

📊 Analytics & Statistics:

Measurement, monitoring, charting, history, and export are all free.

Perfect for anglers, hikers, pilots, weather watchers, and anyone who feels the change when pressure drops.

⚠️ Requirements: The app requires a device with an atmospheric pressure sensor.

⚠️ About storm warnings: Storm warnings and forecasts are estimates based on pressure trends measured by your device alone. They are not a meteorological forecast and can be inaccurate or miss events entirely. Do not rely on them for safety-critical decisions — always check an official weather service.
