Built around the reading

Useful detail, without the noise

The live dashboard keeps pressure, quality and trend context together. Open the deeper tools only when you need them.

Read the device barometer in hPa or kPa, then apply a manual or altitude-assisted calibration for your preferred reference.

Five-minute chart points make overall movement easier to read, while movement, gaps and abrupt changes are treated with caution.

Log readings, inspect individual entries, and export selected ranges as CSV or a readable PDF report.

Home Screen widgets and Live Activities keep current pressure and logging status close at hand.

Private by design

Atmospheric Pressure stores readings locally for charts, logs and exports. Files leave the app only when you choose to save or share them.

Atmospheric Pressure is not an official weather forecast, aviation or marine instrument, emergency warning tool, or safety-critical system.
