CrashKit is an open source development tool which will automatically catch uncaught exceptions, trap signals, and sends them to an app`s developer by email or straight to your bug database.
CrashKit catches uncaught NSExceptions. It also traps signals that the operating system sends when the App touches memory that doesn’t belong to it or executes illegal operations.
The signal handlers unwind the stack frame and try to find out exactly where the crash happened. This bug report can then be emailed or sent to FogBugz.
