This app can be found in both the Android and Apple markets. It is currently on sale right now at a bargain price of only $2.99 on the Android Market. It allows me to navigate my computer on an Android tablet, smartphone, or device from anywhere in the classroom. I love this, because I don't like to be stuck up at the Smartboard/in front of the room all the time. I like the ability this app gives me to easily move around the room, but still navigate the computer/class activities. See the video below for a description!
