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

Duet turns your iPad or iPhone into the most advanced Remote Desktop or 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 or choose the desktop to wirelessly connect to. The Duet desktop app will automatically detect your device, and transform it into a high performance touchscreen display.

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.

I love the app and don't understand the bad reviews about it being a rip-off. On every website where you can download the program for the PC, it explicitly states how much each subscription costs & THAT it costs something. Perhaps you should have read first.

Funktioniert super

Mit meinem Mac Pro von 2013 konnte ich mein iPad nicht per Sidecar als zweiten Monitor verbinden. Duet air ist die Lösung. Es ist sogar ein Spiegeln des Monitor für den Teleprompter möglich. Ich hab‘s nicht gleich richtig eingerichtet bekommen. Der Support ist super schnell und freundlich. Die 21,99€ jährliche Gebühr lohnen sich für mich auf jeden Fall. Ich bin so glücklich, dass ich in Cat Mulvihills YouTube Kanal die Empfehlung für diese App bekommen habe.

Eine Woche kostenlos, dann 22€/Jahr

Unter ner kostenlosen App verstehe ich was anderes 👎
Dazu ist die zugehörige Windows App ca 230MB groß. Schlank geht anders. Nach der Info 1 Woche Trail direkt wieder deinstalliert.
