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 the Home rail, and create channels from the New menu.
  • Track thread to-dos and message FYIs in the new Feed.
  • Your main assistant is now called Chief Think Agent.

Desktop

  • Browse beside conversations with multiple tabs, a pop-out window, and page annotations you can send to chat.
  • Dictate prompts and start Grok live voice from the composer, with restored transcripts and text paced to reply audio.
  • Queue follow-up messages or steer active chat turns, and keep saved model selections after restarting.
  • Search Space conversations and use replies, reactions, and configurable notifications.

Companion Sync

  • Paired devices receive thread messages and progress updates more promptly and reliably.
  • Pairing codes stay available as devices connect, and paired device removal controls are restored.
  • Sphere invitations can wait for recipient device registration and recover from interrupted delivery.

Reliability

  • Shared conversations recover more reliably after reconnects and interrupted sync, while preserving newer edits and thread deletions.
  • Conversation updates better preserve your scroll position and the thread you have open.
  • Sign in and Create account actions make account-only features clearer while signed out.
