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 see the latest revision.
  • Keep saved artifact styling and see when an artifact already has a copy in a Sphere.
  • See the agent's enforced work scope, with recalled context restricted to authorized sources.

Desktop

  • Reopen shared channels more reliably and retain Space message delivery status across restarts.
  • Reach the latest conversation messages with a jump control positioned above the composer.
  • Enjoy cleaner typing indicators that hide your own activity and suppress private echoes.
  • Keep saved onboarding transcripts through a smoother welcome experience.

Companion Sync

  • Manual sync reports failures instead of waiting indefinitely.
  • Cancellation remains effective as Companion work is accepted and delivered.

Reliability

  • Slack reconnect recovery avoids repeated rapid retries when failures persist.
  • Vault saves and shared-state updates do less redundant work.
  • Pending hosted uploads recover more reliably when retrying.
