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.
  • Keep saved artifact styling and see when an artifact already has a copy in a Sphere.
  • See the agent's enforced work scope, with recalled context limited to authorized sources.

Desktop

  • Open shared sidebar channels in chat and preserve Home sidebar conversations.
  • Start fresh drafts from Sphere landings while keeping sub-sphere names.
  • Follow agent progress inline and reach the latest messages with a jump control above the composer.
  • Identify shared Spheres with compact icons and avoid seeing your own typing indicator.

Reliability

  • Restore account navigation more reliably at startup and keep selections scoped to the current account.
  • Improve shared channel creation, reopening, invitations, and owner deletion.
  • Keep nested thread conflicts available for review and reduce chat submission stalls.
  • Track Space message delivery more reliably and prevent delivered messages from appearing pending.

Companion Sync

  • Report failed manual sync attempts instead of waiting indefinitely.
  • Preserve cancellation requests through Companion delivery.
