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 their 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 limited to authorized sources.

Desktop

  • Keep Home sidebar conversations accessible and open shared channels in the correct chat.
  • Preserve Sphere and sub-sphere names when starting new conversations.
  • See more consistent thinking status and reach the latest message above the composer.

Companion Sync

  • Manual sync reports failures instead of waiting indefinitely.
  • Cancellation is preserved through Companion request processing and delivery.

Reliability

  • Space message delivery status survives restarts and matches the correct message.
  • Shared channels reopen more reliably, and invitations recover missing owner keys before delivery.
  • Slack reconnect recovery backs off after repeated failures.
