The Details about how to use it is inside the app.
Basically, the application will read the signal level at 4 different spots around you and tell you which direction it might be.
Due to the environmental effects and my lack of experience, the App may not work so well or NOT WORK AT ALL！！
I originally wrote this app for myself because i was curious about the many wifi-access points broadcasting around us. This is the first version, if you have feedback please let me know!
