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 thread to-dos and message FYIs together in Feed.
  • Navigate nested Spheres and threads from Home, and create Spheres or channels from the global New menu.
  • Browse beside your conversation, open multiple tabs, and share annotated pages with your agent.

Desktop

  • Queue follow-up messages or steer an active chat turn.
  • Dictate prompts with recording controls and clearer microphone setup feedback.
  • Search Space conversations, reply to messages, and add reactions.
  • Use automatic model routing and restore saved task models after restarting.

Companion Sync

  • Receive paired thread messages and progress updates faster and more reliably.
  • Keep pairing controls stable during background refreshes, with clearer connection status.
  • Keep Sphere invitations pending until the recipient registers a device.

Reliability

  • Keep your reading position and open conversation steady as background updates arrive.
  • Recover interrupted invitations and shared Space sync more reliably.
  • Stay responsive during Slack catch-up and workspace startup.
  • Review shared Space conflicts while preserving conflict drafts across refreshes.
