Perfect!!!

I think I found the perfect App for my Training. Even I tried different Apps before.

Yes, in the beginning it looks a bit overloaded to me but it becomes more and more clear by using it.

The most important thing is the pricing. I love it to donate by my own will. And sure I did it already. In this app you can feel the passion and soul of the developer.
In the beginning I had some issues with missing data, but after a quick Email support I could solve it.

Thank you πŸ™πŸ»πŸ™πŸ»πŸ«ΆπŸΌπŸ«ΆπŸΌ

Very good app!

It’s so so easy to use and control VERY TUFF

Perfect Companion

Exactly the tool I was looking for to connect Apple Health data with intervals.icu.
Great that it is free with the option to support the developer - a must have!

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.
