#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.

Très efficace

Après la déception d'astropad (29€ tout de même) j'ai hésité avant de télécharger duet, profitant de la baisse de prix récente je me suis lancé. C'est de la bombe, pour 10€ ça joue très bien le rôle du deuxième écran. Parfait sur l'ipad pro 12.9" avec macbook pro retina 13" lui aussi. Ca permet vraiment de déployer un véritable espace de travail de modélisation 3D ou de montage video n'importe où, et le tactile marche sur le deuxième écran. Le branchement par cable est obligatoire mais au moins l'ipad reste chargé c'est cool.

Une des meilleurs applications de productivité, je recommande sur ipad pro ; très fluide.

Correcte au début de l'installation mais instable

L'application fait en effet ce qu'elle promet dans la description mais elle est instable, vivement une mise à jour !! L'application ne sait pas gérer les jeux vidéo, je pensais m'en servir pour prolonger mon pc gamer et non ça ne fonctionne pas l'image est coupée ce qui fait que le jeu n'est pas du tout fluide, pourtant n'est pas très gourmand, je vais retenter avec LOL, j'utilise un iPad 2. Sinon dernièrement, l'application ne fonctionne pas, j'ai redémarré mon iPad, je l'ai fermé dans le multitâche mais malgré tout ça ne marche pas, l'application est en attente : il y a un message qui me demande de connecter l'iPad au PC ce qui est déjà fait. Pour ceux qui hésite, continuer à hésiter, ne pas se fier uniquement aux commentaires positifs. C'est vrai que 10€ c'est assez cher mais ça reste quand même moins cher qu'un écran ou le pack office.
J'espère très prochainement une mise à jour qui stabilise l'application et qui permet de faire des jeux (60fps).

Superbe application

Comment faire pour changer de coté le bord de l'écran...
