I've used Hockeyapp a few years ago for testing iOS apps and the whole workflow was a nightmare because of Apple's restrictions. You had to get users to send in IDs, add the IDs to Apple's site, download a file with the IDs in them, add the file to your app then build and deploy each time you wanted a new tester. You can't run OSX on e.g. AWS/EC2 so setting up continuous integration was troublesome and there was only unofficial third party tools for building from the command-line. Xcode and app installs would also fail all the time with obscure errors about certificates and Googling for solutions turned up hundreds of threads with different solutions and other developers being stumped.

Have things improved?

Beta testing with Android is easy. You can build the app on any OS you want from the command-line and send the app to anyone with no restrictions.
