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 window, and page annotations you can send to chat.
  • Collaborate in Spaces with invitations, replies, reactions, conversation search, and shared read state.
  • Let Auto select models for your work, with provider usage controls and fallback when providers are unavailable.

Desktop

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

Companion Sync

  • Pair devices with persistent codes, easier copying, and clearer connection status.
  • Keep pairing controls stable during background checks and pair another phone after the first connects.
  • Preserve Space participant names and photos through joining and sync recovery.

Reliability

  • Space messages appear locally with clear pending status while awaiting delivery.
  • Recover interrupted invitations and shared conversations more reliably while preserving local edits and thread deletions.
  • Open your workspace sooner and attach files without waiting for a full search refresh.
  • Slack replies retain thread context and continue promised work before sending a final response.
