Needs Updated ASAP

I just purchased a Bowflex and was hoping to find an app that would allow me to customize a workout and see videos of various exercises. This app promises that, but does to follow through. Im running iOS 8.1.2 on an iPhone. The videos are buggy. Also, I created workouts, but the app crashes every time I try to click on an exercise in my workout. I can still use the app for some guidance, but paid for the options that arent working. Update please!
