Totally true that TestFlight / Play Store uploads are available within 15 min, but in our experience, nobody wants to push to those platform that frequently, and force many upgrades of the app every day, so instead they do nightly builds at best. More importantly, it doesn't help if people don't have the right phone. We would love to help you with this use case, does an emulator in the browser works for you or do you need to install to phones?
