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 Spheres.
  • Share child Spheres in place while preserving their position under the parent.
  • Approve owner device trust in Settings and recover trusted access more reliably.

Desktop

  • Find Spheres with a searchable sidebar switcher and a pinned Create Sphere action.
  • Place attachments inline with your prompt and remove them by deleting their tokens.
  • Follow the full active progress trail and use clearer notifications, menus, and sharing labels.
  • Edit Sphere settings inline and send feedback without leaving your current workspace.

Companion Sync

  • Queued prompts, cancellations, and delivery outcomes recover more reliably across reconnects.
  • Concurrent companion streaming uses less desktop processing, and failed manual syncs report errors.
  • Collaboration names and Sphere navigation stay more consistent across desktops.

Reliability

  • Conversation drafts and delivered messages are better preserved during navigation and sync conflicts.
  • Private profile names and recalled information stay within their authorized sharing scope.
  • Updates retain retry progress across relaunches and recover more reliably from interrupted installs.
