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

  • Collaborate in Spaces with invitations, conversations, message reactions, replies, and search.
  • Dictate prompts in Orbit and Space conversations with recording controls and setup guidance.
  • Use Auto to choose models across desktop and cloud runs, with provider preferences and usage limit controls.

Desktop

  • Type more smoothly, keep your reading position as conversations update, and jump to the latest messages.
  • Switch computers within existing threads and see branch and line changes in coding conversations.
  • Manage notifications from an inbox with dismissal and granular preferences.
  • Start private, agent-guided integration setup from Spaces, with explicit approval before publishing.

Reliability

  • Keep Space read status consistent across devices and preserve thread deletions during sync.
  • Discover newly shared Spaces without restarting and resume partial invitations without resending successful ones.
  • Preserve unsaved provider and Devices settings during background refreshes.
  • Open ThinkOS links in the installed app and view image attachments more reliably during active conversations.
