Cortez Duo turns your iPhone or iPad into a Bluetooth keyboard and trackpad for any Mac you can see. Pair once, point your phone at the screen, and type, scroll and click. NOTHING TO INSTALL ON THE COMPUTER Cortez Duo shows up as a standard Bluetooth keyboard and trackpad. No app, driver or helper runs on the Mac. If a keyboard is allowed, Cortez Duo is allowed. WHAT IT DOES • Keyboard. A full keyboard with modifier keys and macOS key bindings. • Trackpad. Use your phone's screen as a precision trackpad and scroll surface. • Fill password. On a Safari login page, Cortez Duo turns on VoiceOver on the Mac, finds the username and password fields through the camera, types the password you choose from your iOS AutoFill behind Face ID, and turns VoiceOver off again. The password leaves your phone only as keystrokes over Bluetooth. PRIVACY Cortez Duo has no account and no server, and it makes no network requests. The camera shows you the screen you are pointing at; anything it reads is read on your phone and never uploaded. No analytics, no ads, no third-party SDKs. Erase everything the app stores from Settings > Privacy & Data. WHAT YOU NEED • iPhone or iPad running iOS 26.2 or later • A Mac with Bluetooth, paired once as a keyboard Privacy policy: cortez.is/private Terms: cortez.is/terms Support: cortez.is/support Cortez Duo is made by RALL DIGITAL LLC.
