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

  • Collaborate in Spaces with invitations, replies, reactions, conversation search, and synced read state.
  • Browse beside your conversation with multiple tabs, page annotations, and a separate browser window.
  • Queue follow-up messages or steer an active response without waiting for it to finish.

Desktop

  • Use Auto model selection and restore saved task models after restarting.
  • Choose Ollama or Apple Intelligence during onboarding, with clearer local setup checks.
  • Dictate prompts with clearer microphone permissions, recording controls, and input feedback.
  • Keep your reading position and open conversation steady as new messages arrive.

Companion Sync

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

Reliability

  • Recover interrupted Space invitations and member removals more reliably.
  • Preserve local edits and conflict drafts during sync, with conversations for reviewing conflicts.
  • Stay responsive while Slack history and saved workspace content load.
  • See current tool activity separately from answers, with fewer stale running indicators.
