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 Spaces, invite participants, and chat with message replies and reactions.
  • Dictate prompts with recording controls, clearer feedback, and guidance for missing setup.
  • Use Auto to select models for desktop and cloud work, with provider preferences and usage-aware routing.

Desktop

  • Review and dismiss notifications in a new inbox, with granular controls for alerts.
  • Edit and delete routines from the thread drawer, and configure webhook triggers.
  • Keep model choices across conversations and manage provider usage limits.
  • Rename your Chief of Staff or change its appearance by clicking its avatar.

Reliability

  • Preserve newer local edits during sync and refresh open windows when synced changes arrive.
  • Recover more reliably from interrupted Space setup and cloud computer setup.
  • Keep unsaved provider settings drafts and recover your desktop account after sign-out.
  • Continue long-running provider work beyond thirty minutes.
