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 alongside each conversation with multiple tabs, a separate browser window, and page annotations you can send to your agent.
  • Collaborate in Spaces with invitations, replies, reactions, conversation search, and synced read state.
  • Let Auto choose an eligible model while respecting your model exclusions, preferences, and provider limits.

Desktop

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

Companion Sync

  • Pair devices with persistent codes, native copy controls, and clearer connection status.
  • Keep desktop pairing controls stable during background checks and recover paired conversation delivery more reliably.

Reliability

  • Space messages appear locally with a clear pending state while delivery catches up.
  • Recover more reliably from interrupted Space invitations and reconnects while preserving local edits and conversation deletions.
  • Load the workspace sooner and keep typing more responsive in long conversations.
