Process is actively developed and goes through rigorous testing, but sometimes things can slip through. Let me know if it crashes for you--most importantly, let me know what you were doing when it happened if it tends to happen frequently.
We recommend enabling crash reports so we can see what happened. Please do so by going to Settings on your device and navigating to General>About>Diagnostics & Usage and checking Automatically Send. This will allow crash reports to be sent to Apple and forwarded to us, so we can better identify any problems.
If you are interested in helping further, please contact us about being a beta tester. You’ll also get to use new features before they’re available in the Store.
