This app as of 1.0.3 is not compatible with 10.9.1. I updated today only to be told DisplayPad will not run. Deducting a star until then.
Overall I like this app. However, over even 802.11N networks it will sometimes disconnect. Unfortunately the only way to reconnect is to go to the Mac and pull down the menu to select it, which defeats the remote access element if you do not simply want to use it as a second screen. As a second screen, on a Retina iPad, the screen is either too low res or too high res. There does not seem to be a happy medium to allow one to accurately hit targets while giving one enough screen real estate to justify the slowdown in response.
I am hoping the Dev has not abandoned it, but given the last update was almost a year ago, this might be the case. We shall see.
