Barometer: Pressure & Altitude

Barometer is the most accurate barometric pressure tracker, altimeter, and weather change predictor for Android. Read live atmospheric pressure in hPa, mmHg, or inHg in seconds.

Whether you forecast weather changes, track altitude on a hike, or monitor pressure for fishing, hunting or migraine prediction — Barometer turns your phone into a precision weather station.

▶ MAIN FEATURES

• Barometer — live atmospheric pressure (hPa, mbar, mmHg, inHg, atm)

• Altimeter — pressure-based altitude in meters or feet

• Weather pressure trend — 6-hour rising/falling/stable indicator

• Sea-level pressure correction with location auto-detect

• Altitude calibration with known reference height

• Pressure history chart — last 24 hours

• Sensor fallback — uses GPS altitude if no pressure sensor

• Real-time barometer needle gauge with smooth animation

• Dark mode for outdoor use

• Works fully offline — no account, no ads block

▶ HOW TO USE

1. Open Barometer and grant location permission for sea-level correction

2. Read live atmospheric pressure on the dial

3. Switch units (hPa/mmHg/inHg) by tapping the value

4. View the 24-hour trend graph for storm prediction

▶ WHO USES BAROMETER

• Hikers and mountaineers tracking altitude without GPS battery drain

• Fishermen and hunters predicting bite and game activity by pressure

• Pilots and paragliders cross-checking altitude

• Migraine sufferers monitoring pressure drop triggers

• Storm chasers and weather hobbyists watching front passages

• Drone pilots verifying barometric altitude

• Sailors and boaters reading marine weather pressure

• Skiers and climbers calibrating mountain altitude

• Weather geeks tracking long-term pressure trends

• Asthma sufferers correlating symptoms with pressure changes
