BaroScan: Altimeter Barometer

Barometer & Altimeter turns your phone’s built-in pressure sensor into a simple, offline tool for outdoor use, hiking, and everyday weather awareness.

WHAT YOU GET

• Live barometer — See current atmospheric pressure on a clear dial, updated in real time from your device sensor.

• Altitude estimate — Calculate approximate elevation from pressure changes. Choose meters or feet.

• Weather trends — Follow pressure over the last few hours to spot rising, steady, or falling conditions. Get plain-language hints such as fair weather, rain expected, or storm warning.

• Pressure chart — View recent readings on a chart so you can see how conditions are changing.

• Calibration — Set sea-level pressure manually or calibrate with GPS for more accurate altitude readings. Switch between hPa, mbar, and inHg.

• Saved measurements — Bookmark readings with a name, notes, and optional photo. Compare two or more saved points side by side.

• Storm alerts — Optional notifications when pressure drops quickly, so you can react before conditions worsen.

BUILT FOR OFFLINE USE

No weather API required. Readings come from your phone’s barometer only, so the app works without an internet connection for core features. Location is used only when you choose GPS calibration.

WHO IT’S FOR

Hikers, pilots, campers, sailors, and anyone who wants a pocket barometer and altimeter without carrying extra hardware.

REQUIREMENTS

Works best on devices with a barometric pressure sensor. Without one, pressure and altitude features are not available.

IMPORTANT

Barometer & Altimeter is a utility app for personal reference. It is not a substitute for professional weather instruments, aviation altimeters, or official forecasts. Always use appropriate safety gear and trusted sources when weather or altitude matters for your safety
