Works well enough

I've just tried it for a bit, the app prompted me to review it or buy it, so I'd say it works pretty well, I'm using a Macbook Air 2015 with an iPad Air 2, a recommendation for those with similar products: run it in the 30 FPS power saving mode rather than 60 FPS as I found that 60 FPS was quite laggy on the iPad. Also, there is quite a bit of lag when opening Mission Control, but if you can stand that or don't use Mission Control often it should be good.

Better than duet

I am using this in two ways: as a mirrored touchscreen display, and a second (and third) display. First off, this app works perfectly. The only problem I was running into was that the virtual Touch Bar was a little finicky, but I realized that “Automatically hide and show the dock” has to be on. Once I figured that out, everything else came together and now I am very impressed with this app. It’s responsive, and there are so many options for resolution. It even gives my standalone MacBook Air (no iPads connected) an on-screen Touch Bar, but that wasn’t using the mobile app. Definitely 5 stars, even the free version with interruptions. Not super annoying, and they don’t undo any display settings or delete unsaved work. Anyway definitely still buying the paid versions. Very pleased.

Works Great; better than Duet

This free version is fantastic. You get the same experience as the paid version, except for an interruption every 7 minutes, which is the perfect amount of annoyance that if you really can't afford to pay it's still totally livable.

I've also used Duet display, which is more expensive than even the paid version of this 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.
