What do you need help with?


Duet is the first high performance solution to use your iPad as a second display for your Mac. Unlike other second display apps, duet's display has zero lag.


We accomplish this by turning your iPad into a second display using the USB to 30 Pin or Lightning connection. It is far more stable than Wi-Fi, especially for people on the go. You don't have to worry about your 802.11n network, your router settings, whether you're on a VPN, or if you're downloading or uploading too much data to use your display. Duet just works.
