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.
  • 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 in place while preserving their position under the parent.

Desktop

  • Find Spheres with a searchable sidebar switcher and a pinned Create Sphere action.
  • Edit Sphere settings inline and see clearer labels for sharing status and conversation audiences.
  • Read menus, attachment labels, and notifications more easily with improved typography and contrast.
  • Follow the complete agent progress trail inline and send feedback without leaving your current workspace.

Companion Sync

  • Queued messages, cancellations, and delivery outcomes recover more reliably across interruptions.
  • Companion steering stays tied to the intended active turn.
  • Collaboration names and member profiles stay more consistent across desktops, including simultaneous edits.

Reliability

  • Shared Sphere navigation and invitations recover more reliably after startup or sync interruptions.
  • Conversation drafts stay separate across sessions, and older synced state is less likely to overwrite newer work.
  • Paused sharing now explains its status and offers recovery actions.
  • Update installation retries recover more reliably across relaunches.
