Awesome but crashes – Fitness Trainer - Exercise & Workout Guide Review

I downloaded over 40 workout apps and if it didn't crash I would give it a 5. It has improved my workout regiment tremendously and educated me on how to properly execute exercise moves in healthy and beneficial ways. Fix the crashes please. I'm on a iPhone 6, iOS 9, dunno what others are on but bug fixing could make you the number one exercise app in my mind.
