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

Desktop

  • Start Grok live voice from the composer, with saved transcripts and words paced to reply audio.
  • Dictate prompts with clearer microphone feedback and setup guidance.
  • Queue follow-up messages or steer an active chat turn.
  • Use Auto model routing and restore saved task model choices after restarting.

Companion Sync

  • Receive paired thread messages and status updates faster and more reliably.
  • Keep pairing controls stable during background refreshes and remove paired devices from desktop settings.
  • Resume interrupted Sphere invitations and defer delivery until the recipient registers a device.

Reliability

  • Keep your reading position and open conversation stable as new messages arrive.
  • Recover shared conversations more reliably after interrupted sync while preserving newer local edits.
  • Stay responsive during startup and Slack catch-up.
