 In 2016, [Google decided to discontinue](https://support.google.com/maps/answer/6333516) _My Tracks_ and stopped distributing it via the Google Play store in April 2016.
 Then [Plonk42](https://github.com/plonk42) conducted some maintenance work until 2016, so _My Tracks_ could still be used (based upon version _Google's MyTracks_ version 2.0.6).
 Plonk42's version is available [here](https://github.com/Plonk42/mytracks).
