Duet Display, the software that was launched as a way to turn an iPad into a secondary Mac display, has launched support for Android. The new Duet Display for Android app enables users to turn an Android smartphone, tablet, or Chromebook into an extra display for use with a PC or Mac computer, a feature that is particularly useful when working outside of the office.

Apple made the Duet's main product defunct with the launch of its Sidecar feature, which now directly offers a way for using an iPad as a secondary Mac display. Users had anticipated an eventual arrival of Duet Display for Android given the sudden change in its primary market.

As with iPad, Android and Chromebook users can turn their devices into secondary displays for a main PC or Mac computer by connecting the two with a USB cable. Users must install the free Dual desktop client on their computer and the Duet Display Android app on their supported secondary device.

Duet supports gestures and touch control, enabling users to scroll and zoom, among other things, directly on the secondary device. The Duet Display for Android app costs $19.99 USD, but is temporarily discounted on the Google Play Store at $9.99 USD.
