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 inside conversations, expand them, and save copies to a Sphere.
  • Keep artifact app data encrypted and synced with its Sphere.
  • Place attachments inline with your message text and remove them by deleting their tokens.

Desktop

  • Find Spheres with a searchable sidebar switcher and a pinned Create Sphere action.
  • Share child Spheres in place while preserving their position under the parent.
  • See clearer sharing, private conversation, and paused-sharing labels with recovery options.
  • Read active progress more easily, use clearer menus and notifications, and send feedback without leaving your current context.

Companion Sync

  • Collaboration names sync more reliably across desktops while keeping private address names out of shared profiles.
  • Queued companion messages and active-turn instructions retain their intended conversation through retries and recovery.
  • Failed manual syncs and remote message deliveries show clearer outcomes.

Reliability

  • Drafts and delivered messages stay consistent when switching conversations or receiving sync updates.
  • Shared Spheres and accepted invitations recover more reliably after interrupted sync.
  • Agent work scope is visible, with stronger boundaries around private context and recall.
  • Update retries recover more reliably across installation attempts and relaunches.
