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

Desktop

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

Companion Sync

  • Receive paired-device messages and progress updates faster and more reliably.
  • Manage pairing with persistent manual codes, clearer connection status, and restored device removal controls.

Reliability

  • Recover interrupted invitations and reconnect shared conversations more reliably.
  • Preserve newer local edits and conflict drafts during sync.
  • Keep ThinkOS responsive during Slack catch-up and conversation history loading.
  • See clear Sign in and Create account actions when accessing account features while signed out.
