EtherWaker allows your phone or tablet to wake up PCs which have a Wake-on-LAN feature. Just configure your computer's hardware address into EtherWaker and then select it from the list, and it will turn your PC on, over your home's wifi network.
Etherwaker can now scan the local subnet for active hosts, and will automatically add them to the list. Also, interface updated to support Android 4.0 and 4.1.
