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 preserved styling and clearer indications of existing copies.
  • Manage Sphere settings inline while preserving your current Sphere state.

Desktop

  • See agent work scope and responding-agent progress directly in your conversation.
  • Open shared sidebar channels in chat and keep Home sidebar conversations available.
  • Start fresh drafts from Sphere landings with the correct Sphere context.
  • Jump to the latest message with controls positioned above the composer.

Reliability

  • Shared, private, and guest channels recover more reliably during startup and sync.
  • Space message delivery status stays accurate when confirmations arrive late.
  • Sphere settings better protect against stale saves and preserve state during refreshes.
  • Agent recall respects the authorized Sphere context and current attachment sources.

Companion Sync

  • Manual sync reports failures when the Companion connection cannot complete.
  • Cancelled requests remain cancelled through delivery and recovery.
  • Saved answers and pending uploads recover more reliably after interruptions.
