Who has experience or recommendations regarding the distribution of iOS apps to pilot users / test users?
I know about services as TestFlight enabling you to distribute test / beta versions of your apps during development.
- session tracking of your test users
- in-app questions to gather feedback
- remote logging
- in-app updates
Testflight has been acquired by Apple. We use it for distribution of test apps for internal and external testing. Remark that the number of users for internal testing is limited.
Android: for distribution on Android you can accomplish this via the Google Play store.
We are also using HockeyApp (has been acquired by Microsoft) for distributing test builds to test devices and internal test users.
