So Slick

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

A friendly request

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.

Response from developer

Thank you for letting me know about this. I'll look into it and see if I can get a fix into the 3.3 release.

Flawless Integration with Apple Health

I use an Apple Watch and had been recording most of my workouts natively on the Workout app along with the Apple Health app. As I started to get a bit more serious with my training I decided I wanted more stats and load estimations to better guide my training and that’s when I created an Intervals.ICU account. Well, this app made the exporting of my data to Intervals.ICU seamless. Love the app, totally recommend!

Tip jar spam

Having to dismiss the tip jar pop up constantly made me uninstall the app.

Response from developer

That's not true. Just tap close and you will never see it again.

Freaking Awesome!
