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 your agent's work scope and the complete active progress trail.

Desktop

  • Adjust Sphere settings inline while preserving your conversation state.
  • Open shared sidebar channels in chat and keep Home conversations available during navigation.
  • Keep Space drafts separate when switching sessions, with clearer conversation spacing and access to the latest messages.

Companion Sync

  • Companion sync stays responsive while settings are being updated and reports failed manual sync attempts.
  • Message delivery and cancellation outcomes remain consistent across reconnects and account changes.

Reliability

  • Shared Space messages retain more accurate delivery status through retries and timing conflicts.
  • Older synced state is less likely to overwrite newer conversations or Sphere changes.
  • Agent recall respects the authorized Sphere context, including private descendant Spheres.
