This app does not access your location in any way. It does not use GPS, and will not get your relative sea level. However you can adjust it manually.


This app tracks and records your altitude based on the barometric sensor in your phone. Not all phones have a barometric sensor. If your phone is capable you can use this app to access it and record readings.

It is based on the data logging software in the Angstrom Metrology family of apps.

-track and record a stream of data points.

-It has a manually set calibration factor, which you can change to adjust your readings.

-It also can "zero" out the pressure for measuring relative differences if desired.

-This version has the ability to email/download your data files.

Feel free to contact us with any concerns or questions about the app.
