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

  • Get started with conversational provider setup and a persistent Welcome that preserves your setup history.
  • Open Home from the Lens Rail to browse nested Spheres, Agents, and Chats while keeping Home selected as you open threads.

Desktop

  • Access shared Spheres from a dedicated rail and find collaboration Spheres in settings.
  • See participant activity in text threads and more consistent unread indicators.
  • Get clearer sharing labels, history consent, preview progress, and retry options when sharing fails.

Companion Sync

  • Keep completed responses and message order intact across device sync.
  • See a consistent Chief identity as companion replies arrive.

Reliability

  • Queued messages and collaboration work recover more reliably after offline restarts, with Slack retries preserving delivery order.
  • Sign-in continues through brief connection failures, and cloud settings recover after server outages.
  • Update progress refreshes automatically, and artifact save progress stays visible in long forms.
