#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.

Great alternative to SideCar

I started using Duet even before Apple announced SideCar. At that time it was amazing: crisp picture, low battery consumption and touch screen support on an iPad. I am not using Apple Pencil and I do not need any of the premium features if the app, so I cannot really comment on whether it is useful for artists. The only thing I noticed is that since SideCar launch they focused on this feature set much more than on image quality. That is why the rating is only 4 stars - SideCar gives much nicer image quality on iPad Pro and is more versatile.
One thing where Duet is impeccable is support for wired connection. In case you use corporate vpn that prevents Apple features (like SideCar and a few others) to work properly, Duet is the only reliable solution.
The developer is also very responsive - they confirmed a problem that I escalated within a couple of days and offered a workaround while the developers are working on a proper fix.

This is such a great app for maximising what an I pad can be I use it with my mid range Hp laptop and it works fine my iPad isn’t even the latest thing it’s an air 2 showing you don’t need a pro or something that costs the earth to get it to work. I wasn’t 100% certain on how to set it up at first as I’m not the most tech savvy person however I sent an email to the team and heard back in about 20 mins they spent time going through the possible issues until I knew what to do the set up was simple and they guided me through it, most people probably wouldn’t need this assistance but it was some of the best for speed and efficiency. The app works great and helps me cut the time it takes to do things drastically it is legitimately worth it and if there are any issues I find it hard to believe contacting the help team wouldn’t sort it as they are so efficient. I never had twin displays before so never knew the benefit now I not only have one but an ultra portable one that I use on a daily basis. Genuinely one of the best apps for productivity out there and I can’t recommend enough especially for editing things like photo and video if you need to constantly switch between windows and programs such as Vegas pro ,paint ,after effects or just the file explorer . Being able to drag and drop from the file explorer directly to Vegas without having to minimise or alter anything is amazing and time saving.

This app is a scam as it does not do what is saying will do .
The app does not work pen is not working properly and the mouse lags a lot as well as the windows from your desktop will lag as well in This app and if you want to use it without lag and use the pen that’s what they say you can do this only if you pay SUBSCRIPTION if you buy the app without subscription you can not use the app for what was described to be used also the description and the info on the app’s page is MISLEADING all. Contacted the developer and they apologised for the not working app and sent me the links to ask for a refund but Someone Mary was having a bad day and refused the refund so in conclusion I have been scammed as they did not want to refund the App and they did not give me any reason why they refused to refund me as the app did not work on my Pc pen is not working only in some apps and the cursor is 15 millimetres away from the pen tip also the mouse lags a lot and is unusable as well so the app is Rubbish if you buy it and without subscription is unusable you just waste £10 for nothing . Don’t get scammed get the free app it works with the pen for free .There are other apps that offer a free thrill and they work with the pen and pressure sensitivity and pen tilt as well some free and some payment based but steel you have a free trial to see how the app works Like Easy canvas for example yes is £2 more but it does work for the intended purpose

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.

We're sorry if Duet isn't working correctly on your setup. If you can report this to our support team at team@duetdisplay.com, we can help you troubleshoot the issue. Make sure to refer to this review! 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 Air & Pro are for a small market but more work.
