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.
  • Manage ToDos, FYIs, and Fun in one Feed, with a Done list and controls to reopen or remove ToDos.
  • Choose Queue or Steer when sending a message during an active run.

Desktop

  • Find Spheres with a searchable sidebar switcher and personalize them with colors and animated backgrounds.
  • Keep attachments inline with your message text and preview Brain images and local videos.
  • Follow steadier agent progress timelines that emphasize meaningful work.

Sphere Sharing

  • Start shared threads immediately while sharing finishes in the background.
  • See clearer audience labels, invitation status, and recovery options when sharing pauses or fails.
  • Start contextual direct messages with Sphere members, including when your Sphere access is read-only.
  • Open shared Spheres more reliably across your computers while preserving private conversation boundaries.

Reliability

  • Recover conversations and agent actions more reliably after restarts or interrupted syncing.
  • Reduce memory use and background disk activity to keep the desktop responsive during sync.
  • Get clearer delivery failures and shared-agent reply errors, with fewer duplicate messages.
  • Retry interrupted update downloads and recover failed installations more reliably.
