So close to perfect

I love this so close to perfect. Had some minor issues with the server app. Both Mac and Windows it won't let me set the resolution to match the iPhone 4/4s. This seems to be causing some display issues when using them. I'd also really like the windows and Mac editions to have the same user experience and options. The only other thing I can think of is support for more than one device at a time and to be able to use it over wifi. I know you went sub to avoid the issues of competitors but it would be nice as an option.

Anyone want a touchscreen Mac? Duet is your solution!

I have used Duet for over two years now, and it has truly been an amazing experience. From the streamlined experience to the features you can’t get on some iPads and Mac (such as the Touch Bar, and Sidecar), Duet is truly a must have for anyone who has an iPad and Mac. Furthermore, many people have wanted a touchscreen Mac. Not available with Apples Sidecar, touchscreen is permanently enabled when using Duet. And better still, with a subscription to Duet Air, you iPad officially becomes a 2 in 1 - a Mac with a touchscreen that you can take anywhere in the office or home (so long as your Mac is awake in another room). And if you encounter any issues, the Duet team had always been very helpful! This feature of you Mac becoming an iPad (or an iPad with macOS) has so many helpful uses, from zoom calls, to taking study notes. Duet is truly a solution for those who want to carry their Mac around the office (like an iPad), showing their work to a supervisor, or anyone in general who has asked for macOS to come to the iPad.

Perfect for when I’m on the road

My wife and I are often on the road and feel hamstrung when only operating on one screen, so when I discovered Duet I was super excited as we also had a couple iPad Pros which have approximately the same size screen as our Surface Laptop. We ran via cabled connection initially which ran perfectly, but the iPad didn’t charge so it went flat after a while. I then worked out that I could buy the Air upgrade so I could charge and work at the same time. Initially we hot-spotted both the iPads and laptops and found it really slow. So I reached out to support and got a super quick response for some things to try. It’s now behaving perfectly both via our home wireless network and when hot-spotting. Having the ability to easily transport a “second screen” by way of an iPad is simply awesome and the support assistance is just the icing on the already sweet cake.
