I’ve started using a cool mobile app called WifiMap.
It does something quite simple but also quite useful.
When you have the app on your phone and you are using a public wifi (open or password protected), you simply open WifiMap and it gives you the opportunity to “pin” that wifi on a map and supply the password, if there is one.
Then, when you are out and about, maybe in a foreign city, maybe in a new neighborhood in the town or city where you live, you can open WifiMap and find the nearest wifi that you can get onto and do work or play.
That’s it. It’s simple. But quite useful.
