App description:

Remotely control the volume of your Macintosh from your iPhone or iPod Touch. A perfect complement to Apple's Remote app. 

No special software needed on your Mac! 

** ISSUE #1: The app does not work on iOS 7 yet. I am working on an update.
** ISSUE #2: The setup video is not working within the app. To setup your Mac to work with this app you need to:
1) Open "System Preferences"
2) Select "Sharing"
3) Check the box next to "Remote Login"
4) You should now be able to control the volume from your iPhone/iPod Touch

NOTE: This app only works with Macintoshes.
