Ok so one day I came up with the idea of a wi-fi pin pointer. What it is is simply an arrow on the screen that shows which way the wi-fi network you are connected to is coming from. I thought this could be useful when you have a low level of wi-fi and want to know which direction you should move to get a better signal. Other then developing it, I see only one problem. Because of the arrow having to refresh so rapidly, it would probably be a battery waster if used for too long. I think it could be a moderately useful and simple app. I don't know if you guys think the same, but the idea just came to me. Please leave comments and reactions.
