Apple's acquisition of TestFlight is about to make a big splash when it comes to the general public gaining greater access to developer betas. A short while ago, developers began receiving emails from iTunes Connect alerting them of the wider availability of beta tester invites.
Developers will be able to invite up to 1000 testers to beta test their iOS apps, and it's all done through a simple email invitation initiated through the iTunes Connect website. Once sent, recipients of the email can accept the invitation and can install the beta app on their iOS devices within the TestFlight app. It seems like a win-win situation for everyone involved. Developers get a super-simple way to manage and send out beta invites, and beta testers potentially receive broader access to the apps that interest them most.
