I am a super cheap guy so 7 bux a month makes me cringe. If you are reading this, you are probably not as cheap as me lol
The app is great. I like that you can mix equipment and auto generate an exercise. I have a tendency to skip exercises that i dont like and this helps me do the things i am weak on. A surprisingly helpful feature is the voice that magically knows when i am thinking of stopping and says "come on!" And the like. It is very helpful to people who exercise solo.
