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 previews, and see the latest revision.
  • Save artifacts to a Sphere with preserved styling and a warning when a copy is already saved.
  • Manage Sphere settings inline with protection against stale saves.

Desktop

  • See agent work scope and responding progress within the conversation.
  • Open shared sidebar channels in chat and keep Home conversations available during navigation.
  • Start fresh drafts from Sphere landings with the correct Sphere context.

Companion Sync

  • Manual Companion sync reports failures instead of waiting indefinitely.
  • Queued prompts, cancellations, and recovered answers are handled more reliably.
  • Accepted private channels become available more reliably after sync.

Reliability

  • Space message delivery status stays accurate when updates arrive out of order.
  • Recall respects authorized context, including permitted private descendant Spheres.
  • Shared channel reopening, invitations, and nested conversation conflict review are more reliable.
