BasicAirData GPS Logger is a simple App for recording your position and your path.
It's a basic and lightweight GPS tracker focused on accuracy, with an eye to power saving.
It works offline (without internet connection), it has NO integrated maps.
This app is very accurate in determining your altitude: enable EGM96 automatic altitude correction on settings!
You can record all your trips, view them with any installed external viewer, directly from the in-app tracklist, and share them in KML, GPX, and TXT format in many ways.

The app is 100% Free and Open Source.


IMPORTANT NOTES:
Depending on your Android Version, if you want to run GPS Logger reliably in background, you have to disable ALL the battery optimisations. For example you could verify in Android Settings, Apps, GPS Logger, Battery that the Background Activity is allowed, the Location Permission is set to "Allow all the time" (Android 10+), and the Battery Usage is Not Optimised.
