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

  • Browse beside each conversation with multiple tabs, a detachable window, and page annotations you can send to your agent.
  • Collaborate in Spaces with invitations, replies, reactions, conversation search, and read state that follows you across devices.
  • Use Auto model routing with provider preferences and usage limits.

Desktop

  • Dictate prompts in Orbit and Space conversations with recording controls and setup guidance.
  • Rename conversations manually and keep your reading position as new messages arrive.
  • Manage notifications in an inbox and choose whether macOS alerts appear while ThinkOS is focused.

Companion Sync

  • Pair companions with persistent manual codes, copy controls, and clearer connection status.
  • Keep desktop pairing controls stable during background refreshes and retain a new pairing code after the first phone connects.

Reliability

  • Space messages are saved locally with a clear pending state when delivery is unavailable.
  • Space invitations and shared messages recover more reliably after interruptions, while participant names and photos remain visible during catch-up.
  • Conversations show more accurate running status, and image attachments remain available during active turns.
