This is a great app, probably the best free kettle bell workout bar none. EXCEPT, the latest update has some great features but the voice prompts and sounds to change exercises cancels background music entirely, basically you can’t play music with this workout. I’ve turned it all off in settings but it still dings and stops my music. It’s very hard to focus and get in a rhythm with no music. Fix this and it’s 5 stars all the way!
