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 a Sphere with their styling preserved and see when a copy is already saved.
  • See the agent's enforced work scope, with recalled context restricted to authorized sources.

Desktop

  • Start new conversations with the correct Sphere or sub-sphere context.
  • Reopen shared channels in the correct conversation and keep live channels visible in collaboration.
  • Reach the latest messages with a jump control positioned above the composer.
  • Your own typing activity no longer appears in prompt composers.

Reliability

  • Shared Sphere invitations recover missing owner keys before delivery.
  • Space message delivery status is retained and matched to the correct message.
  • Slack reconnection recovery handles repeated failures more reliably.

Companion Sync

  • Manual sync reports failures when the Companion connection stalls.
  • Cancellation is preserved while Companion work is accepted and delivered.
