I cannot listen to music and use this app at the same time with my headphones simply because this app's sound will not work. I've checked my sound settings, app notification settings, uninstalled, reinstalled, and the app continues to be silent. They've reached out before but I'm tired of this app! Avoid it and download HEVY! Muscle Booster, don't reach out anymore bro, I'm out! ✌🏾

The app was 5-star till they changed the interface so you can no longer see a visual of the next exercise. Instead, they have introduced an enormous timer, which takes up too much screen. Until then it was a very usable app - now, you have to work out what's coming (gather the appropriate weights, get in position ec) from the written description. Not helpful!

The workouts are okay. Asling as they show up on your screen. For the last 2 days my daily workout hasn't shown up at all and it's only been the morning challenge thing. If I slide to the next day I can see it but than when the next day comes it's gone again. And the steps don't track correctly. It stops tracking at random parts of the day. I'll be walking around my neighborhood or the grocery store and still be at the same amount of steps I was before I started.
