About this application

AAT (Another Activity Tracker) records outdoor activities using the GPS receiver of an Android device. It logs a track while an activity is in progress and derives the usual figures from it: distance covered, elapsed and moving time, speed, and elevation change. Cycling is the activity type the application is built around, though the recording mechanism itself is not specific to it.

The application runs on Android only; there is no desktop or iOS counterpart, and it is intended to be carried on the device during the activity rather than used to import data from a separate bike computer or watch. Recorded activities are kept on the device for later review.

It is published by Lukas Bai under the GNU General Public License, version 3 or later, which means the source may be inspected and modified, and derived versions must be distributed under the same terms.
