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

  • Find nested Spheres, pinned threads, and recent conversations from the Home sidebar.
  • Track thread to-dos and message FYIs together in the new Feed.
  • Browse beside your conversation, open multiple tabs, and share annotated pages with your agent.

Desktop

  • Queue follow-up messages or steer an active response without waiting for it to finish.
  • Use automatic model selection and restore saved task models after restarting.
  • Create Spheres and channels from the New menu, and start with a fresh Chief of Staff draft on launch.
  • Dictate prompts with clearer microphone permission guidance and recording controls.

Companion Sync

  • Receive paired conversation messages and progress updates faster, with independent threads able to run concurrently.
  • Keep pairing controls and connection status more consistent during background refreshes.
  • Resume interrupted invitations and hold delivery until the recipient registers a device.

Reliability

  • Keep your reading position and open conversation steady as new messages arrive.
  • Recover shared conversations more reliably after interrupted sync, reconnects, and device changes.
  • Keep ThinkOS more responsive during startup and Slack catch-up.
  • Review conflicting shared changes while preserving conflict drafts across refreshes.
