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 preserved styling and clearer controls.
  • See the agent's work scope and follow thinking and response progress inline.

Desktop

  • Edit Sphere settings inline while preserving your current Sphere state.
  • Open shared sidebar conversations in chat and start fresh drafts from Sphere landings.
  • Keep Home sidebar conversations available and reach the latest message above the composer.

Companion Sync

  • Manual sync now reports failures instead of waiting indefinitely.
  • Message delivery status more reliably reflects delivered Space messages.
  • Accepted private channels recover more reliably after sync.

Reliability

  • Startup and account switching more reliably restore the correct navigation and conversations.
  • Sphere settings reject stale saves, and recalled context stays within the agent's authorized scope.
  • Queued prompts, saved answers, retries, and cancellations recover more consistently.
  • Shared channel reopening, invitations, and nested thread conflict review are more reliable.
