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 and expand HTML artifacts directly in conversations, with the latest revision and controls to save Sphere copies.
  • Artifact app data is encrypted and syncs with its Sphere, with recovery guidance and conflict review.
  • See the agent's work scope and complete progress trail, including observed tool activity and recorded durations.

Desktop

  • Find Spheres faster with a searchable sidebar switcher and numbered rail navigation.
  • Use clearer composer menus with consistent alignment, improved contrast, and popovers that stay within the window.
  • Review notifications in a redesigned popover that stays open while scrolling and offers Dismiss all.
  • Edit Sphere settings inline, with sharing actions separated from sync controls.

Companion Sync

  • Queued Companion messages retain their context more reliably when moved into an active conversation.
  • Companion follow-ups stay attached to the intended active turn across completion and recovery.
  • Manual sync reports failures more clearly, and cancellation outcomes survive delivery and recovery.

Reliability

  • Shared conversations reopen and recover more reliably, with clearer delivery errors and fewer stale state updates.
  • Space drafts stay with their conversation session when switching between chats.
  • Startup navigation resumes after account data is ready, preserving the intended destination.
  • Agent recall respects the authorized Sphere scope, helping keep private context out of unrelated conversations.
