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 inside conversations, expand them, and save copies to a Sphere.
  • Artifact app data is encrypted and syncs with its Sphere.
  • Place attachments inline with your message text and remove them by deleting their tokens.
  • Share child Spheres while keeping them under their parent.

Desktop

  • Find Spheres with a searchable sidebar switcher and a pinned Create Sphere action.
  • See clearer sharing status, private conversation labels, and recovery options when sharing is paused.
  • Read the full active progress trail without leaving the conversation.
  • Use clearer menus and notifications, with more readable labels and popovers that stay within the window.

Companion Sync

  • Queued messages and active-turn follow-ups retain their intended conversation through delivery and recovery.
  • Delivery failures remain visible, and removing queued messages requires confirmation.
  • Manual sync reports failures instead of leaving the outcome unclear.

Reliability

  • Shared Spheres retain their identity and placement more reliably across desktops and paused sharing.
  • Conversation drafts stay with their session, and delivered messages recover more reliably after sync conflicts.
  • Startup navigation waits for account data, reducing misplaced or missing conversations.
  • Agent work scope is visible, and recalled context respects authorized Sphere access.
