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 interactive HTML artifacts directly in conversations, expand them, and save copies to a Sphere.
  • Keep saved artifact app data encrypted and synced with its Sphere.
  • Share child Spheres in place while preserving their position under the parent.

Desktop

  • Find Spheres with a searchable sidebar switcher and a pinned Create Sphere action.
  • Place attachments inline with your message text and remove them by deleting their tokens.
  • Read clearer menus, attachment labels, notifications, and active agent progress.
  • Open feedback in a panel while keeping your current workspace in view.

Companion Sync

  • Move queued companion messages into active work more reliably while preserving their context.
  • Keep delivery errors and cancellation outcomes visible through retries and recovery.
  • Receive clearer failure feedback when manual companion sync cannot complete.

Reliability

  • Distinguish Sphere sharing status from conversation audiences, with clearer paused-sharing explanations and recovery actions.
  • Recover access to accepted Sphere invitations more reliably.
  • Preserve newer conversations, drafts, and shared Sphere placement during startup and sync.
  • Keep agent recall within the authorized work scope.
