Very good exercise program that is fun!

Positives:

It is fun and designed motivating. Also, I've read literature on the subject, here is but really practiced with concrete and varied exercises times.
The app is divided into training sessions and sets an internal counter when you have practiced enough.

Thank you!

What would I do better:

- An app notification, when to move on to the training
- A note which screen size and lighting would be optimal. (I do the Übgungen on the SGS4 and wondering if a tablet would be better.)
