I can’t believe how elegant this app is for a free, 3rd party app. Absolutely love this for mobile use.

by Or*****, 2026-08-13

I have been using this app for a week now and I absolutely love it. This app gives you detailed information about your workouts and offers comprehensive analysis of your performance. So far there is one issue that bothers me. I currently live in China, the Chinese government requires all domestic mapping services to use a coordinate system called GCJ-02, which differs from WGS-84. This results in a fixed offset of workout routes displayed in the app. I wonder if you could look into it and come up with a transformation of the two coordinate systems, so that I can see my workout route clean and neat. Much appreciated.
