iPhone and iPad through TestFlight

  • ThinkOS has completed Apple's TestFlight review and is approved for public testing. We're distributing the iOS app through TestFlight for now because we're making rapid changes and want to deliver fixes and improvements quickly before the full App Store release.
  • Install Apple's free TestFlight app on your iPhone or iPad if you do not already have it, then open the ThinkOS public TestFlight link on that device and tap Accept or Install.
  • New ThinkOS builds appear in TestFlight as they are released. You can update manually or enable automatic updates in TestFlight. Expect frequent changes, occasional rough edges, and features that may move while the early release develops.
  • TestFlight builds are available for up to 90 days. We plan to keep a current build available, but if a build expires, return to TestFlight for the newest one.
  • Feedback is part of this early release: send notes from TestFlight, including screenshot feedback when useful, so we can reproduce issues and improve the next build.

Highlights

  • Personalize agents with animated Neue avatars and custom colors that stay readable.
  • Get started through conversational provider setup in a persistent Welcome thread.
  • Preview scoped Sphere Agent delegations before handing off work.

Desktop

  • Find Spheres, agents, and chats in the new Home view, with a dedicated rail for shared Spheres.
  • Keep Sphere tree branches expanded and retain your selected view when opening threads.
  • See clearer sharing progress, retry errors in place, and choose whether to include existing thread history.

Companion Sync

  • See agent reactions and participant activity shared across clients.
  • Keep completed responses and message ordering consistent across device sync.
  • Recover queued messages and collaboration work after offline restarts.

Reliability

  • Fix crashes affecting live Neue avatars on desktop.
  • Reduce noisy collaboration updates and unnecessary conflict review notices.
  • Improve sign-in recovery, Sphere removal, and automatic update progress refresh.
