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 separate browser window, and page annotations you can share in chat.
  • Collaborate in Spaces with invitations, replies, reactions, conversation search, and synced read state.
  • Use Auto to select models for your tasks, with provider preferences and usage controls.

Desktop

  • Dictate prompts, rename conversations, and switch computers within existing threads.
  • Manage alerts through a notification inbox and granular preferences, including macOS notifications while ThinkOS is focused.
  • Keep your reading position as conversations update, with a shortcut to jump to the latest messages.

Companion Sync

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

Reliability

  • Space posts are saved locally with clear pending status when delivery is unavailable.
  • Space invitations and shared messages recover more reliably, while participant names and photos remain visible during catch-up.
  • Slack replies better preserve conversation context and follow through on promised work before sending a final response.
