I only have access to one physical device (iPhone 5c) which I used alongside the simulator to test my universal app (supports iPhone and iPad) during development. I have a TestFlight beta build approved by Apple for testing, and I'm about to start inviting external TestFlight testers, but before I do so, I wanted to know if there's anyway I can check the thinned download size of my beta build for each iOS device without actually having direct access to all physical devices, is that possible and if so how?
