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.
  • 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 without moving them out of their parent.
  • See clearer sharing, paused-sharing, and conversation audience labels, with recovery options when sharing pauses.
  • Read active progress more easily with inline agent updates, clearer menus, and improved notification scrolling.

Companion Sync

  • Queued prompts, cancellations, and delivery outcomes recover more reliably across reconnects.
  • Manual sync reports transport failures more clearly.
  • Collaboration names stay consistent across desktops while private address names remain out of shared profiles.

Reliability

  • Drafts stay separate between conversation sessions, and older sync snapshots no longer replace newer state.
  • Shared channels and Sphere navigation recover more reliably after startup or interrupted sync.
  • Private recall and agent context stay within the authorized work scope.
  • Update retries recover more reliably after relaunch or an interrupted installation.
