Rather than using Dropbox or a web app like Marvelapp to preview UI mockups on my Android tablet I want to preview my PC window (Photoshop screen) in real-time instead so I can make rapid changes to speed up my workflow.

I know there is an app for IOS like this (forget the name) and the only app for Android I could find is called 'Android Design Preview' which is limited to working on Nexus devices only. I could also use a remote desktop client but with a prototyping app you can crop the screen so it only shows the mockup design.

Note: When I say prototyping and mockup I do not mean for creating wireframes but an app that will allow me to preview my Photoshop window on my PC in real-time. These apps allow you to connect the device via USB cable so the information is sent to the device instantly, although there maybe apps that use RDP also.
