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 Spheres with preserved styling and encrypted app data that syncs with the Sphere.
  • See the agent's work scope and complete active progress trail, with clearer tool activity and durations.

Desktop

  • Adjust Sphere settings inline while keeping your conversation context.
  • Browse a cleaner notifications popover that stays open while scrolling and offers a Dismiss all control.
  • Enjoy clearer dialog edges, more consistent cards, and tighter conversation spacing.

Companion Sync

  • Shared conversations reopen more reliably and retain message delivery outcomes across retries.
  • Companion sync better preserves cancellations and reports failed manual sync attempts.
  • Space drafts stay tied to their session, and older synced state is less likely to replace newer changes.

Reliability

  • Recover saved answers, pending uploads, and artifact backups more reliably after interruptions.
  • Keep recalled information within the agent's authorized scope.
  • Reduce background sync overhead and repeated connection recovery attempts.
