Works great; Better than Duet

This app is great. It works just as you'd expect. Not all resolutions are equally responsive, so if you see people complaining about lag, know that tuning resolution can solve this. This lag is just a factor of the hardware limitations of the USB connection, something that will affect all apps like this in the same way.

I've also used Duet display, which is more expensive than Yam, but Yam is much better. Yam has more resolution options, moderately better performance, and support for split-screen multitasking on supported iPads, a great feature that Duet lacks.
If you don't need to use this with windows, I highly suggest Yam over Duet.

Doesn’t work on windows

So I downloaded this app because it follow close to duet display and is a little cheaper duet works great on my Windows 10 pc and my MacBook which is great even though they advertise it for Mac. However yam display offers no such windows client and never expressly say it isn’t compatible with windows like all the other display apps do if a windows client is available in the future this app would get 5 stars but I give it one 2 because they don’t communicate in their description it’s Mac only and I’m now out $8

Wonderful app with excellent support.

Have been using it for long time. Excellent app!

Update- Still glad that I invested money in Yam Display instead of Duet. Support is great and one gets regular updates.
