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 around Spheres with unified navigation and actionable Activity.
  • Queue follow-up messages or steer an active chat turn.
  • Browse beside your conversation, open multiple tabs, and share annotated pages with your agent.

Desktop

  • Find conversations with Space search, rename threads, and rename agents directly from their profiles.
  • Use Auto model routing and restore saved task models after restarting.
  • Dictate prompts with clearer recording controls and improved microphone permission handling.

Companion Sync

  • Receive paired thread messages and status updates faster and more reliably.
  • Pair devices with persistent codes, native copy controls, and clearer connection status.

Reliability

  • Recover interrupted Space invitations and reconnect more reliably while preserving device identity.
  • Keep your conversation position and open thread stable during background updates.
  • Stay responsive during Slack catch-up and startup, with clearer live tool activity as agents work.
