From the developer:
HockeyApp is a way to collect live crash reports, get feedback from your users, distribute your betas, and analyze your test coverage. This program automatically groups similar crashes in an elegant and intelligent way. Also crash reports appear in real-time with fully symbolicated stack traces.
