I am searching for an Android App which let me track a route and save it at the end into a *.gpx file.

I tried a couple of navigation Apps (like MapFactor, Here, ...) but they do not offer such a basic feature.

Maybe someone here in this forum can recommend one app.

If possible this App should
- be able to automatically turn on internal hardware GPS device when started and turn it off at exit
- let me define the tracking interval (e.g. every 10 seconds).

Any suggestions?

Thank you
Peter
