Some developers releasing apps on TestFlight as a less restrictive App Store alternative

According to a new report, some iPhone and iPad developers are choosing to publish their apps to TestFlight, which is Apple's service for over-the-air installation and testing of iOS apps, and leave it at that. Users, assuming they know where to look, can download and use these pieces of software via the TestFlight app, which is available for free on the App Store.
