This handy little app will help you optimize your wireless network as well as find others with ease, and all for the great price of free. You can get this Android app from Google Play and start optimizing your wireless network immediately.
Besides being fun this app is useful when trying to pin down which wifi channels are less crowded. It has an easy to read display with good amount of customizable features. With the the Scan interval option set at its shortest you can watch your signal increase or decrease in near real time. One of the view options included is the signal strength over time which i found quite useful when checking for interference.
