#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.

Hace lo que promete!

Funciona muy bien para extender la pantalla de mi MacBook con mi iPad.
No le pongo 5 estrellas porque para poder utilizar el pencil de Apple con plena funcionalidad, hay que pagar una suscripción...entendería pagar un modulo extra, pero no una suscripción anual. Revisen su política!

Qué decepción

La app no está mal, la uso desde que salió, pero ¿20 euros AL AÑO para poder usar el pencil?.... Venga ya, os habéis pasado. Si fuese un único pago no dudaría en hacerlo, poder usar el ipsd como tableta gráfica bien lo vale, pero obligar a la suscripción me parece abusivo. La alternativa, que era Astropad también se ha pasado al modelo de subscripción, y encima tres veces más caro. Ojalá Apple desarrolle algún día soporte nativo para usar el ipad como una tablet y ambas compañías, en las que muchos gastamos un dinerillo para ver como luego nos dejaban tirados, sufran las consecuencias de su codicia y blablabla. Rollo justiciero.

Tomadura de pelo

Al principio funcionaba perfectamente, pero desde hace un mes, se acabó: o se cuelga o sale una pantalla negra.
