Locating iPhone & iPad app crash logs
If an app is freezing or crashing regularly, we may request crash logs from you to help us diagnose any issues. Crash logs contain information about what the app was doing just prior to the crash.
To find a log file, please sync your iPhone or iPad first with iTunes, then locate the correct log file for the app using the path for your OS below. The log file’s name should start with the app’s name.
Mac OS X
~/Library/Logs/CrashReporter/MobileDevice//
Windows 7
C:\Users\USER NAME\AppData\Roaming\Apple computer\Logs\CrashReporter\MobileDevice\\
Once you’ve located the correct file, please email it back to us.
