Barometer M1 app measures air pressure and altitude using the built-in barometric pressure sensor on your device.

App features a Barometer for weather, an Altimeter for outdoor activities, a barometric Trend

The Altimeter helps you track your altitude changes based on the change of pressure. Just set your reference pressure and altitude in order to use the Altimeter for checking how high up the mountain you have climbed.

Barometer M1 can be used such as climbing, trekking, hiking and even stair climbing.

Features:
. Contains accurate barometer and altimeter
. Unit support for pressure (mb, inHg, kPa, atm, Torr, psi, hPa, mmHg), altitude (meter,
feet)
. Calibrate the barometer using GPS altitude, GPS location and nearest airport
information/METAR, or manually entered correction
. Measure height (building/mountain/hiked/climbed) using relative altitude feature
(check Settings)

Please note: It only works on devices that contain a barometer
