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 message FYIs in Feed.
  • Browse beside conversations with multiple tabs, page annotations, and a separate browser window.
  • Queue follow-up messages or steer an active chat turn.

Desktop

  • Use prompt dictation and Grok live voice with restored transcripts, saved voice turns, and text paced to reply audio.
  • Choose automatic model routing and restore saved task models after restarting.
  • Search Space conversations, rename threads, and keep your reading position as messages arrive.

Companion Sync

  • Receive paired thread messages and activity updates faster and more reliably.
  • Manage paired devices with clearer connection status, persistent pairing codes, and restored removal controls.

Reliability

  • Recover interrupted Space invitations and sync more reliably while preserving newer local edits and conflict drafts.
  • Keep ThinkOS responsive during startup and Slack catch-up.
  • Find clearer Sign in and Create account actions when accessing account-only features.
