Bad App – Brazilian Butt – Personal Fitness Trainer App Review

I used to have this app on my old phone, it worked really well then. Now that I have it on my new phone it doesn't work as well and it glitches out. All I want to do is work out but I can't when the timer just stops and nothing happens.
