#1 best-selling iPad app in US, Japan, UK, Germany, and 17 other countries!

Duet turns your iPad or iPhone into the most advanced extra display for your Mac & PC. Developed by a team of ex-Apple engineers, Duet offers unparalleled performance and display quality - all with zero lag.

Be twice as productive by multitasking with two screens. And for those that travel, have a portable way to stay productive.

To get started, plug your iPad into your desktop using your charging cable. The free Duet desktop app will automatically detect your device, and transform it into a high performance touchscreen display.

There’s no need to worry about unreliable Wi-Fi, laggy performance, pixelated screens or managing network passwords.

Interact with Mac & PC like never before, with touch & gestures, including two-finger scrolling, pan and zoom.

And with our latest release, you can even add a touch bar to any iPad with any Mac.

With Duet Pro, you can turn your iPad and Apple Pencil into a professional graphics tablet. We’ve re-engineered our rendering algorithms for ultra-responsive drawing, optimized specifically for designers, illustrators and artists.

Duet Pro also unlocks pressure & tilt sensitivity, hover, palm rejection, and more to seamlessly draw in the most powerful programs for professionals. Get precise control in Photoshop, Corel Painter, Lightroom, ToonBoom, Illustrator, Manga Studio and more.

Excellente application et support rapide et efficace

Je l’utilise principalement avec Ableton Live 9 Suite version 9.7 (les deux fenêtres ouvertes en même temps) et et également avec Painter 2017 (les nombreuses palettes), cela fonctionne impeccablement et de façon très fluide sur mon iPad.
Pour des raisons de convenance personnelle et logicielles (eh oui les nombreux plug ins musicaux), j’utilise Mac OS 10.9 sur mon MacBook Pro et le dernier update optimisé pour Mac OS 10.12, de l’application gratuite pour Mac ne se lançait pas sur mon ordinateur.
J’ai bénéficié de la part du Team de Duet Display d’une aide rapide et efficace. Un mail clair et précis pour désinstaller proprement l’pllication sur mon mac avec un lien vers une ancienne version du logiciel gratuit et tout est vite rentré dans l’ordre. Encore merci à eux pour leur aide.
A recommander !!!

3 stars here is why

Let me start by saying. Great app good work! But for this money I should be a “complete” app. It is not ok to ask for a yearly subscription for the “pro” features. And specially the wireless option. This is in my opinion a little scam. You know. I’m willing to pay an extra 5 bucks for the app and have all the features than this. There for the 3 stars that could’ve been 5. I hope that the devs read this one day....

Developer Response ,

We do understand your point, and we know it may seem like too much, but in reality, the payment for the subscription is due to the wide range of opportunities that Duet Pro can give our users.

This requires a lot of development to support, and it is only for a small number of users, so the only model that works for us is an ongoing subscription. That is why the main product is a one time purchase, and the niche features like Duet Air & Pro are for a small market but more amount of work
