HockeyApp for iOS has nothing to do with the sport of hockey and everything to do with making developers' and beta testers' lives easier. Time was, in order to beta test an app, you had to tether to iTunes and manual transfer over the provisioning and app files, and you had to do it every time the beta updated -- which could be often. Then services like HockeyApp showed up, and they allowed for direct, on-device, over-the-air (OTA) installation and updates of both provisioning files and apps. Hockey will even alert you when updates are available. Moreover, for developers, HockeyApp provides crash reports, feedback, and analytics.
At Macworld|iWorld 2013 I had to a chance to talk with HockeyApp founder Thomas Dohmke about his service, which has also made life much easier for writers like me who cover apps and are often sent early review copies the same way.
Likewise, making the beta process better results in apps that get tested more often, and more fully, and thus, better final releases for everyone.
