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 in threads, expand them, and save copies to a Sphere.
  • Find ToDos, FYIs, and Fun in one Feed, with a Done list and controls to reopen completed ToDos.
  • Choose Queue or Steer when sending a message while an agent is working.

Desktop

  • Navigate Spheres with a searchable switcher and clearer Channels, Threads, and direct messages.
  • Start threads in the current Sphere, with improved keyboard focus and more consistent returns from Settings.
  • See meaningful agent progress in a steadier timeline that collapses when work finishes.
  • Personalize personal Spheres with colors and animated backgrounds.

Sharing

  • See clearer conversation audiences, invitation status, and next steps when sharing needs attention.
  • Paste or drop files into shared conversations, track uploads, and retry failed attachments.
  • Open shared threads immediately while sharing completes in the background.
  • Recover shared Sphere access more reliably across your computers and retain read-only copies after removal.

Reliability

  • Preserve drafts, private attachments, and conversation history more reliably through refreshes, restarts, and backup sync.
  • Recover stalled Sphere creation and unconfirmed message deliveries with clearer retry actions.
  • Reduce memory use and unnecessary background sync work to improve responsiveness and prevent crashes.
  • Retry interrupted update downloads and recover failed installations more reliably.
