Battery problems and crashes mar a great app

I’ve used this app for years and have done hundreds of workouts with it. Ever since OS7 it drains the battery quickly (a 10 minute workout will take it down 10%), and with iOS8, it crashes if the phone is put to sleep. I love the app, but it needs an update badly.
