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 Feed.
  • Browse alongside a conversation, open multiple tabs, and share annotated pages with your agent.

Desktop

  • Dictate prompts and use live voice with restored transcripts, saved turns, and dedicated Voice settings.
  • Queue follow-up messages or steer an active chat turn.
  • Search shared conversations, rename threads, and keep your reading position as messages arrive.

Companion Sync

  • Receive paired thread messages and work status updates faster and more reliably.
  • Pair devices with persistent codes and manage paired devices from desktop settings.
  • Keep shared conversation read state in sync across devices.

Reliability

  • Recover interrupted invitations and shared Sphere sync more reliably after reconnecting.
  • Preserve drafts, attachments, and saved model choices through refreshes and restarts.
  • Find clearer Sign in and Create account actions when account features require authentication.
