Crashes all the time

I just got the free version and it crashes immediately all the time with an iPhone 6 running iOS 8. My brother-in-law has the paid version and it crashes all the time now too. He has an iPhone 6 Plus running iOS 9. Cant recommend this. Seems like a cool app so please fix this major issue
