Want to gain full control of your Mac straight from an iOS device? Well, that is now made possible thanks to the HomeControl app which is free to boot. Basically, it delivers a free reign of your machine right in the palm of your hand. This web app was developed and can be installed on your local machine alongside access to your iOS device. It will let allow you to control a wide range of features in iTunes, including adjusting the system volume. Not only that, you are able to launch virtually any application in your Applications folder. You will need Mac OS X to have the HomeControl up and running beforehand though, alongside the built-in web server and PHP enabled. Any takers?
