Crashes upon open on IPhone 6 – 7 Minute Workout - Marines Survival Edition FREE Review

I downloaded to re-live some best and worst days of my life - boot. The app promises that but crashes upon opening 100% of the time. The people who get the app to work love it, so I only post this to ask the developer to tweak the app to work on iPhone 6.
