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 new Home rail.
  • Find thread to-dos and message FYIs together in Feed.
  • Browse beside a conversation, open multiple tabs, and share annotated pages with your agent.

Desktop

  • Dictate prompts and start Grok live voice from the composer, with saved transcripts and text paced to reply audio.
  • Queue follow-up messages or steer an active chat turn.
  • Use Auto model routing and restore saved task model choices after restarting.
  • Search conversations, rename threads, and keep your reading position as messages arrive.

Companion Sync

  • Receive paired-device messages and status updates more promptly and reliably.
  • Manage pairing with persistent codes, clearer connection status, and restored device removal controls.
  • Keep conversation read state in sync across devices.

Reliability

  • Recover interrupted Sphere invitations and shared-message delivery more reliably.
  • Preserve local edits and conflict drafts during background sync.
  • Keep ThinkOS responsive while loading conversation history and catching up on Slack.
