Hey, I am Andreas, one of the developers of HockeyApp.net. The service provides some pretty unique features especially advanced crash report management. Crash Reporting is based on PLCrashReporter (see http://landonf.bikemonkey.org/code/objc/Reliable_Crash_Repor...), works also in the App Store with full server side symbolication grouping all crashes by class, method and line number. Let me know if you have any questions.
