Testflight from Apple is a program with which beta testing for iOS applications can be performed. It consists of a service, which provides the functions, and an app on the test device that interacts with the user. Testflight is especially interesting from the perspective of developers, because they get faster feedback. Also for companies, the use of Testflight is an advantage, because what helps in development increases productivity.
Testflight has been used by app developers as an beta test platform since several years. Apple bought the service this year in connection with the acquisition of Burstly, the company that originally developed the platform. Apple has redesigned the program and made it available as an integrated iOS 8 service for both developers and testers.
