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 shared read state.
  • Browse alongside each conversation with multiple tabs, page annotations, and a detachable browser window.
  • Let Auto select models for your tasks, with provider preferences and usage limit controls.

Desktop

  • Dictate prompts with recording controls and clearer setup guidance.
  • Rename conversations, keep your reading position as messages arrive, and jump to the latest messages.
  • Manage alerts through a notification inbox and choose whether macOS notifications appear while ThinkOS is focused.

Companion Sync

  • Pair from desktop with persistent manual codes, copy controls, and clearer connection status.
  • Keep a fresh pairing code available after connecting the first phone.
  • Recover interrupted Space invitations and discover newly shared Spaces without restarting.

Reliability

  • Space posts are saved locally with a clear pending state when delivery is unavailable.
  • Space member names and photos remain visible during reconnection and catch-up.
  • Conversation deletions and newer local edits are better preserved during sync.
  • Slack replies retain thread context and more reliably finish requested work before sending a final response.
