Get ready for Posterior on iPhone

Public TestFlight access is being prepared. The Posterior invitation is not available here yet; installing TestFlight alone does not grant access.

  1. Install Apple TestFlight on your iPhone from the App Store.
  2. Return here for the Posterior invitation when public access opens.
  3. Once your invitation is accepted, install Posterior in TestFlight and open the app. If you already have a Posterior account, sign in with it.

Requires iOS 16.4 or later. Need help? Contact Posterior support.
