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 in shared or private conversations with replies and message reactions.
  • Dictate prompts with active recording controls, clearer feedback, and guidance for missing setup.
  • Use Auto to select models for desktop and cloud work, with provider preferences and quota-aware routing.

Desktop

  • Review and dismiss notifications in a new inbox, with granular notification preferences.
  • Edit or delete routines from the thread drawer and set up webhook triggers.
  • Keep model selections across threads and customize your Chief of Staff's name and appearance.
  • Receive a notification when a cloud computer is ready and recover interrupted cloud setup.

Reliability

  • Better preserve local edits during sync and refresh open windows when synced changes arrive.
  • Recover more reliably from interrupted Space creation, invitations, and account sign-out.
  • Retain unsaved provider settings drafts and improve notification delivery and catch-up.
  • Read conversations more comfortably with consistent message layouts and corrected header overlap.
