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

  • Customize agents with animated Neue avatars that reflect what they are doing.
  • Get started through a persistent Welcome conversation with guided provider setup.
  • Preview scoped Sphere Agent delegations before handing off work.

Desktop

  • Browse Spheres, agents, and chats from the new Home view, with shared Spheres in a dedicated rail.
  • See clearer sharing progress, retry failures in place, and review history-sharing consent.
  • Choose whether to retain content when deleting a Sphere.

Companion Sync

  • See agent activity and reactions across connected clients.
  • Keep completed responses and message order consistent across device sync.
  • Preserve queued message delivery through interruptions and recovery.

Reliability

  • Keep Slack and Discord listeners available while ThinkOS runs in the background.
  • Recover Slack work more reliably after offline restarts, with fewer repeated updates.
  • Reduce unnecessary collaboration conflict notices while preserving conflicts that need review.
  • Improve sign-in recovery, live avatar stability, and automatic update progress.
