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 interactive HTML artifacts directly in conversations, expand them, and save copies to a Sphere.
  • Keep artifact app data encrypted and synced with its Sphere.
  • Find Spheres with a searchable sidebar switcher and a pinned Create Sphere action.

Desktop

  • Place attachments inline with your message and remove them by deleting their attachment tokens.
  • See the full active progress trail, tool activity, and recorded durations while agents work.
  • Use clearer Integrations and Plan settings, more readable menus, and improved notification controls.

Companion Sync

  • Share nested Spheres in place while preserving their position in your hierarchy.
  • See clearer distinctions between Sphere sharing, conversation audiences, and paused sharing, with recovery actions.
  • Keep collaboration names more consistent across desktops and approve owner trust when moving between devices.
  • Recover queued messages and delivery outcomes more reliably across reconnects and cancellations.

Reliability

  • Fix an idle memory issue that could cause repeated crashes.
  • Improve startup navigation and Plan loading, including a recovery action when Plan loading fails.
  • Preserve newer conversation state and drafts during sync, account changes, and message conflicts.
  • Improve update recovery across installation attempts and relaunches.
