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, with channel creation and guest invitations close at hand.
  • Find thread to-dos and message FYIs together in the new Feed.
  • Browse beside conversations with multiple tabs, a pop-out window, and page annotations you can share in chat.

Desktop

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

Companion Sync

  • Receive paired conversation 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 shared conversation sync more reliably while preserving local edits and conflict drafts.
  • Keep your reading position and open conversation stable as background updates arrive.
  • Stay responsive during startup, Slack catch-up, and file attachment imports.
