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

  • Navigate nested Spheres and their threads from Home, and create channels from the New menu.
  • Track thread to-dos and message FYIs in the new Feed.
  • Browse beside your conversation, open multiple tabs, and share annotated page screenshots with your agent.

Desktop

  • Dictate prompts and start Grok live voice from the composer, with saved transcripts and words paced to reply audio.
  • Queue follow-up messages or steer an active chat turn.
  • Use Auto model routing and keep saved model selections after restarting.
  • Search Space conversations, reply to messages, and add reactions.

Companion Sync

  • Receive paired conversation messages and work status updates faster and more reliably.
  • Manage paired devices with restored removal controls and clearer connection status.
  • Keep pairing codes visible when connecting additional devices.

Reliability

  • Recover interrupted invitations and collaboration sync more reliably.
  • Preserve conversation scroll position and drafts during background updates.
  • Stay responsive while message history loads and Slack catches up.
  • See clear Sign in and Create account actions after signing out.
