Hello Friend Hunter, it is a very good product that you have there; therefore I enclose my development of its pros and cons:
Pros:
To use this App for exercises, you will only need your mobile phone; Their sessions are very dynamic and do not add the strict use of other equipment.
It has alarms, so that the user remembers when to exercise; ideal for people initiated into the activity.
Easy interface and ideal design of the App, which makes it easy to manipulate by the user.
Cons:
- None, in my research I found user suggestions that indicated full satisfaction with the App.
