No any issue on iPhone 4 / iPhone5C /iPhone6 Plus, but on iPhone5s & iPhone6 when your click the digital button, then the app will be crash.

Are you able to reproduce this in the simulator as well? I tried and didn't notice any issue. Unfortunately I don't have an iPhone 5s or 6, so I'm not able to do anything about this myself. If you can provide logs or fix the issue yourself, I will gladly accept a pull request.
