TestFlight was founded December 2010, and was designed as a single platform to test and distribute mobile applications on Android and iOS devices.
Apple Inc. purchased TestFlight's parent company in February 2014, and terminated support for Android as of March 2014. Apple also shut down FlightPath (a mobile analytics solution and a replacement to TestFlight Live) and SkyRocket (a mobile application monetization platform) the same month.
TestFlight is still operated by Apple Inc. however is only available to developers within the iOS Developer Program. Developers signed up to the service are able to distribute applications to internal or external beta testers, who can subsequently send feedback about the application to the developer. The TestFlight SDK additionally allows developers to receive remote logs, crash reports and tester feedback.
