We’ve all had the moment where we are just itching for wifi. But when you’re on the go, that can be tricky. Public wifi sucks, and a lot of establishments don’t give you wifi unless you buy something. So that’s why WifiMapper is so handy. Not only does it show all the wifi hotspots around you, it also crowdsources wifi passwords, meaning you can skip the awkward question of asking a café employee what the wifi code is when you have no intention of buying anything.
