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 conversations, invite participants, and use message reactions and replies.
  • Search Spaces conversations and jump to the latest messages while keeping your place when reading older posts.
  • Dictate prompts with active recording controls, clearer feedback, and guidance for missing setup.
  • Use Auto to select models across desktop and cloud runs, with provider preferences and usage limits.

Desktop

  • Switch machines within existing threads and remember model choices for new conversations.
  • Manage alerts from a notification inbox with dismissal and granular preferences.
  • Edit or delete routines from the thread drawer and set up webhook triggers.
  • Get clearer first-run and integration setup guidance, and personalize your Chief of Staff's name and appearance.

Reliability

  • Preserve newer local edits during sync and refresh open windows when background changes arrive.
  • Recover more smoothly from interrupted Space setup, cloud Brain setup, and account sign-out.
  • Keep unsaved provider settings drafts and maintain conversation scroll position as messages arrive.
  • Receive Slack agent replies more reliably, with replies kept in their threads.
