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

  • Navigate nested Spheres and threads from the new Home rail, with channel creation and guest invitations close at hand.
  • Browse beside your conversation, open multiple tabs, and share annotated pages with your assistant.
  • Queue follow-up messages or steer an active chat without waiting for it to finish.

Desktop

  • Find messages with conversation search, reply and react in Spaces, and rename threads.
  • Choose Ollama or Apple Intelligence during onboarding and use Auto routing to select among eligible models.
  • Dictate prompts with clearer microphone feedback and improved permission handling.
  • Keep your reading position and open conversation steady as background updates arrive.

Companion Sync

  • Receive paired thread messages and activity updates faster and more reliably.
  • Pair devices with persistent codes, clearer connection status, and more stable desktop controls.

Reliability

  • Recover more reliably from interrupted Space invitations, reconnects, and member removals.
  • Restore saved task models after restart and keep progress commentary out of saved answers.
  • Stay responsive during startup and Slack catch-up, with fewer stale running indicators.
