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

  • Create Space conversations, invite participants, and respond with reactions and replies.
  • Search Space conversations and keep read status in sync across devices.
  • Use Auto to select models for desktop and cloud work, with provider preferences and usage controls.
  • Dictate prompts in Orbit and Space conversations, with recording controls and setup guidance.

Desktop

  • Enjoy smoother typing, preserved conversation scroll position, and a shortcut to the latest messages.
  • Switch computers within existing threads and see branch and line changes in coding conversations.
  • Manage notifications in a desktop inbox with granular preferences and dismissal controls.
  • Start private, agent-guided integration setup from Spaces and approve drafts before publishing.

Reliability

  • Discover newly shared Spaces without restarting and recover shared messages after sync interruptions.
  • Resume partial invitations without resending successful ones, and preserve thread deletions during sync.
  • Keep unsaved provider and device settings intact during background refreshes.
  • View image attachments more reliably during active conversations.
