The short version
TestFlight is a free app made by Apple. It exists so people can install apps that are still being built and are not on the App Store. You install TestFlight once, from the App Store, like any other app. Then you use it to install the Workbench. From then on TestFlight is where you go for updates.Why not just the App Store?
Because the Workbench is pre-release, and Apple does not list pre-release software on the App Store. Nor should it — the App Store is for finished products, and this is not one yet. That is also why you cannot search for it. There is no listing. The only way in is the invitation we sent you.Is it safe?
Yes. TestFlight is Apple’s own software, distributed by Apple, and every build that goes through it is signed and checked by Apple’s systems in the same way App Store apps are. You are not sideloading anything, disabling any protections, or jailbreaking anything.The three things that surprise people
Builds expire after 90 days
Builds expire after 90 days
Every TestFlight build has a hard expiry. When it lapses the app stops opening
until you install a newer one.This is Apple’s rule, not ours, and it applies to every app on TestFlight. In
practice we will have shipped several updates before you get close.
Updates arrive far more often than App Store apps

We might ship several builds in a week. Each is a normal update, and TestFlight
can install them automatically if you let it.
