Nice work, thanks for this port!

The power usage seems to be minimal during the tracking which is good!

A problem though, I was not able to save my first track but maybe I did something wrong...

Is there a possibility to change the GPS measurement intervals? I would like to have the ability to modify this depending on the activity/lenght of the tracking.

The area for the map could be bigger, space is wasted at the top and the bottom of the screen. For example, the button for changing the type of map could be somewhere else: pulley menu?

Thanks again for this great app!
