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

  • Navigate nested Spheres and threads from Home, and track thread to-dos and FYIs in Feed.
  • Browse beside your conversation with multiple tabs, page annotations, and a separate browser window.
  • Queue follow-up messages or steer an active chat turn.

Desktop

  • Dictate prompts and start live voice from the composer, with saved transcripts and words paced to reply audio.
  • Search shared conversations, rename threads, and keep your reading position as messages arrive.
  • Choose automatic model routing and restore saved task models after restarting.

Companion Sync

  • Receive paired conversation messages and status updates faster and more reliably.
  • Pair devices with persistent codes, clearer connection status, and restored device removal controls.

Reliability

  • Recover shared conversations and invitations more reliably after interrupted delivery or reconnecting.
  • Keep ThinkOS responsive during startup and Slack catch-up, while preserving drafts through background refreshes.
  • Find clearer Sign in and Create account actions when account features require authentication.
