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

  • Browse beside your conversation with multiple tabs, a separate browser window, and page annotations you can send into chat.
  • Queue follow-up messages or steer an agent while it is working.
  • Collaborate in Spaces with invitations, replies, reactions, conversation search, and synced read state.

Desktop

  • Choose automatic model routing, with Ollama and Apple Intelligence available during onboarding.
  • Find threads under the agent answering them, rename agents inline, and create local Spheres from the New menu.
  • Dictate messages with clearer recording controls and improved microphone permission handling.
  • Keep your reading position and open conversation as new messages arrive.

Reliability

  • Space messages show clearer pending status, with better recovery after interrupted sync and reconnects.
  • Saved model choices return after restart, and live tool activity stays separate from saved answers.
  • Desktop startup and Slack catch-up are more responsive.
  • Companion pairing has steadier controls, persistent manual codes, and more accurate connection status.
