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.
  • Save artifacts to a Sphere with preserved styling and clearer access to saved copies.
  • See the agent's enforced work scope, with tighter limits on recalled context when switching scopes.

Desktop

  • Keep the jump-to-latest control accessible above conversation composers.
  • Avoid seeing your own typing activity in prompt composers.
  • Enjoy smoother Welcome transitions and retain saved onboarding conversations.

Companion Sync

  • Manual sync reports failures when relay connections stall.
  • Cancellation is preserved while Companion work is queued and delivered.

Reliability

  • Space message delivery status persists and tracks the correct delivery receipt.
  • Shared channels reopen at the correct destination and resume publishing.
  • Sphere invitations recover missing owner keys before delivery.
  • Slack recovery stays consistent across reconnects and pauses repeated failed attempts.
