I am aware of reports that Keep Calm Creator 1.0 is crashing on some devices running iOS 6. Currently it seems to be primarily fourth-generation iOS devices (iPod Touch 4G, iPhone 4 and iPad 2) that are affected however I’ve had reports from other users.
The issue seems to be related to a change in how Apple lets developers hide the status bar at the top of the screen from iOS 5 to 6 which has led to it crashing on iOS 6.
I have now submitted an update to Apple that fixes these issues and adds loads of new features. It currently looks like the update should be available early next week (1-2 business days) so issues should be resolved by 9/26/12.
Apologies if you’ve been affected by this bug!
If you’re interested, I’ve also now made my App Store statistics for Keep Calm publicly accessible.
