am asking this because I really need to explain it to my client. My client wants to distribute apps only to his employees for business purposes, like in-house application. He wants the feature like TestFlight which is acting like App Store where we can update the app and install the app every time the developer update the app. He doesn't want to submit his app to App Store. In order to make his employees to use easily, he also said, his employees can install the app easily and show the update easily like Testflight without expire date or limited testers. I found hockey app , but it requires testers to be Hockeyapp members.
