Torr: Barometer Altimeter

SoyApps

About this app

Free barometer & altimeter — real-time pressure, altitude, 10-day forecasts with migraine alerts, automatic history logging, and CSV export all in one app.

The dashboard displays high-precision real-time measurement data, offering peace of mind for mountaineering enthusiasts and outdoor adventurers.
It uses your device's built-in barometric pressure sensor and GPS, allowing offline use.
Real-time trend graphs make it ideal for observing short-term changes during storms, sudden downpours, stair/elevator ascents/descents, or driving uphill.

The altimeter lets you simultaneously view readings from three sources — GPS, QNH (sea-level corrected pressure), and a calibrated value matched to a known elevation such as a trailhead.
Each altitude is displayed visually on an arch gauge, and you can tap each source to learn about its characteristics and accuracy.

For those sensitive to weather changes and suffering from migraines or weather-related illnesses, it provides graphs forecasting barometric pressure and weather for the next 10 days, along with medically grounded headache alert information updated every 6 hours.

Measured barometric pressure data is automatically stored within the app.
A background measurement mode enables measurements even when the app is in the background. You can view accumulated data and export it to CSV files.
