Crashes! – Active by POPSUGAR Review

Loved it the first couple times I used it - great variety of workouts. I suddenly am unable to use the app now though.. It crashes every time I try to open it. I'm on an iPhone 6 with the most up to date software. When I open it, it crashes but does appear as an app that is open.. When I try to get in that way it still crashes but shows its open. Help!
