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 alongside each conversation with multiple tabs, a resizable panel, and a separate browser window.
  • Mark up webpages and bring annotated screenshots into your conversation.
  • Collaborate in Spaces with invitations, replies, reactions, search, and read state synced across devices.
  • Use Auto to select models for your work, with provider preferences and usage limits.

Desktop

  • Dictate prompts with recording controls and clearer setup guidance.
  • Rename conversations, jump to the latest messages, and keep your reading position as replies arrive.
  • Manage notifications in an inbox and choose whether macOS alerts appear while ThinkOS is focused.
  • View plans and complete subscription checkout in the app.

Companion Sync

  • Pair from desktop with persistent codes, easy copying, and more accurate connection status.
  • Keep a fresh pairing code available after the first phone connects.
  • Discover newly shared Spaces without restarting and resume partially completed invitations.

Reliability

  • Space messages appear locally right away with a clear pending delivery status.
  • Open your workspace sooner and attach files without waiting for a full search refresh.
  • Preserve thread deletions, newer local edits, and unsaved settings during sync.
  • Keep Slack replies in the right thread with more consistent conversation context.
