This app is very simple and only allows you to do one thing: control your windows based computers mouse. Unfortunately it's not as user friendly and interesting as it sounds, making it a great concept but something that should be incorporated into other apps and not just on it's own.
When you load up the app, all you'll see is what looks like a touchpad. On the right hand side is a scroll bar and below that are three buttons that read Left, Middle, Right. To the right of that is a little blue arrow that will bring you into settings.
In the settings menu, you have to manually set the Server IP. Then you can choose to show the mouse buttons or scroll area on the app. That's about it. To actually connect, you do need to download the WinRemote software from their website. This isn't explained in the app at all! The software just sits in your toolbar. It doesn't have to be installed or anything. Just run it once.
WinRemote is a great concept that would work excellent with ANY of the current VNC clients out for the iPhone. Unfortunately it's just a standalone concept that requires you to download software to your computer and doesn't even let you change mouse sensitivity. Until it's part of a VNC client, there really isn't any use.
