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 and expand HTML artifacts directly in conversations, see the latest revision, and save copies to a Sphere.
  • Adjust Sphere settings inline while preserving your conversation state.
  • See the agent's enforced work scope, with recall restricted to authorized context.

Desktop

  • Shared sidebar channels open in chat more reliably, and Home sidebar conversations stay available.
  • Agent progress stays inline, with tighter conversation spacing and a jump-to-latest control above the composer.
  • Shared Spheres use compact icons, and your own typing activity no longer appears in the composer.

Companion Sync

  • Companion sync stays responsive during settings changes and reports failed manual sync attempts.
  • Shared and accepted private channels recover more reliably after startup or interrupted sync.
  • Message delivery status more reliably reflects completed delivery, while cancellation survives sync interruptions.

Reliability

  • Startup navigation more reliably loads the correct account's conversations.
  • Sphere settings better protect against stale saves and unauthorized changes.
  • Queued prompts and chat submissions recover more reliably when the app is busy.
  • Slack reconnect recovery avoids repeated rapid retries.
