Love this app  put it on every new phone I buy! REALLY saves battery on any phone. If WiFi is on  the internal radio in your phone is constantly checking for a Wi-Fi signal. This takes power  and a lot of it. This app is smart and simple... it quickly learns your access points  home  work  coffee shop  etc. By using cell tower triangulation: meaning no GPS used. If you help it along learning your access points it it's quicker  but it will figure them out on it's own fairly quickly. Try it and see!
