What Our Users Say

App Store Review

It is incredibly helpful: I never knew how much more productive I’d be

App Store Review

If you travel with a laptop and iPad, you need this app. I needed a second screen, but Duet gives me even more. Full gesture support, customizable shortcuts, Touch Bar, tons of resolution options, and very little battery power. How is this all in one app?

App Store Review

Co-workers can’t believe I can share my desktop on my iPad and my iPhone. Look no further. This is a terrific addition to any office, remote or otherwise.


@duetdisplay is life changing

App Store Review

If you are hesitant about this app, because you think that you’re getting along fine without it, it will make a huge difference.

App Store Review

My Wacom stopped working, and Duet became my placeholder... realizing it supports wireless, touch, has better gestures and is overall more stable then Wacom, I cannot go back. If you are an artist using Photoshop and Zbrush then I suggest trying this out.


Duet Display is still the best app of all time.

App Store Review

I just love this app. Especially when I am travelling for work an working from the company branches. Then I use my iPad as second monitor for Outlook, Lync and other chat while I use the laptop big screen for remote desktop to my workstation at the main office. :)

App Store Review

As head of an NGO, I travel a great deal to remote places around the world. It is very difficult to be productive, as power and internet availability are often a challenge. However when I am able to set up, Duet works like charm to improve productivity.
