I'm just starting to explore the app, but I know it’s been around for a long time. It’s designed for people who frequently download and delete apps. Sometimes, these users are asked for feedback, and this program is what most apps on iOS devices use to allow you to test them. I believe the app developers control what capabilities beta testers have. Some may provide you with access to certain features, while others might not. It seems that TestFlight, the program I’m looking into, doesn’t influence those decisions. Overall, I'm still figuring out the benefits of this program, but so far, I think it's pretty cool! I am just now starting to explore the app but it’s been around forever and it’s for people who download apps a lot and delete apps a lot. They sometimes need your feedback and this is the program that most apps on at least the iOS device comply with for you to be able to test an app. I believe it’s up to the app what capabilities there beta testers can have because I will give you provision of the app and others won’t, but I don’t believe test flight has anything to do with that as I said, I’m still exploring the benefits of this program but so far I think it’s cool
