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.
  • See the latest artifact revision with clearer controls and warnings when an artifact is already saved.
  • See the agent's enforced work scope, with recalled context limited to authorized sources.

Desktop

  • Edit Sphere settings inline while preserving your current Sphere context.
  • Open shared sidebar channels directly in chat and keep Home conversations available.
  • Follow agent progress inline and reach the latest messages above the composer.

Companion Sync

  • Manual sync reports failures instead of waiting indefinitely.
  • Cancellation and recovered answers are preserved more reliably across Companion delivery.
  • Accepted private channels appear more reliably after sync.

Reliability

  • Startup and account switching more reliably restore the correct conversations and navigation.
  • Shared Sphere navigation, invitations, and reopened channels recover more reliably.
  • Space message delivery status stays accurate when updates arrive out of order.
  • Stale Sphere Agent settings saves are blocked, and nested thread conflicts remain available for review.
