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 share in chat.
  • Collaborate in Spaces with invitations, replies, reactions, conversation search, and read state that follows you across devices.
  • Choose Ollama or Apple Intelligence during setup where supported, and use Auto to select models based on your preferences and available capacity.

Desktop

  • Reach Space and channel actions through right-click menus, and create chats, threads, agents, or Spaces from the New menu.
  • Manage account details in a dedicated Account settings tab and rename threads directly.
  • Dictate prompts with clearer recording controls and feedback, plus fixes for microphone permission and silent input.
  • Control notifications through an inbox and preferences, including whether system notifications appear while ThinkOS is focused.

Companion Sync

  • Pair companion devices with persistent codes, native copy controls, and more accurate connection status.
  • Keep pairing controls stable during background checks and recover paired conversations more reliably after interruptions.

Reliability

  • Keep Space posts locally with clear pending status while offline, with improved delivery and invitation recovery after reconnecting.
  • Preserve conversation scroll position, newer local edits, and thread deletions as updates arrive.
  • Load the workspace before full history finishes loading and attach files without waiting for a full search refresh.
