While jailbreaking can bring many benefits, sometimes installing a tweak compromises stability. Removing the offending tweak solves the problem, but the trick is to know which tweak causes the error. The tool CrashReporter can help those with jailbroken devices track down exactly what's causing iOS to crash.
CrashReporter comes in handy when there are many tweaks installed, or when a problem occurs and it's not obvious what is triggering the crash. Once installed, CrashReporter can be configured to send push notifications automatically when a crash is detected. Logs will showcase details related to the crash, including the responsible tweak and its install date.
