I'm in the B2B space and before pushing a new version of our iOS app to the app store, I usually allow some current customers to play around with it for a few weeks of beta.
I was using App.io to let customers emulate the app on web, but they are shutting down that service. Testflight is too clunky (can't ask customers to send me their UDID) and Hockeyapp isn't scalable. I looked into using the Apple Enterprise Account certificate but "technically" you can only share apps internally using that.
I was wondering if others had found solutions for such an issue or what they did for pre-release with corporate customers?
