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

  • View HTML artifacts directly in conversations, expand them, and save copies to a Sphere.
  • See the complete active progress trail and the scope your agent is working within.

Desktop

  • Adjust Sphere settings inline while preserving your conversation state.
  • Navigate shared conversations more reliably from the sidebar.
  • Keep drafts separate across Space sessions and see more accurate message delivery status.

Companion Sync

  • Improve shared conversation recovery after startup, reconnects, and interrupted sync.
  • Preserve delivery and cancellation outcomes across sync interruptions.
  • Report failed manual sync attempts instead of leaving them waiting indefinitely.

Reliability

  • Prevent older sync snapshots from replacing newer conversation state.
  • Keep recalled context within the agent's authorized Sphere scope.
  • Reduce repeated background lookups and improve responsiveness when sending messages.
