Barometer

The barometer features include altitude, incline, decline, ascent and descent. Altitude is measured with an atmospheric air pressure sensor and converts the measured air pressure into an altitude reading. Ascent and descent are shown in meters/feet.

Barometric altitude is automatically calibrated two times via GPS during the first minutes of a session. In the beginning of a session before the calibration altitude is only based on barometric air pressure that can at times be inaccurate depending on the conditions.

Altitude data is post-corrected after calibration, so any inaccurate readings seen during the beginning of a session are automatically corrected afterwards, and the corrected data can be viewed in the Flow web service and app after your session after syncing your data.
