Hey, I'm one of the cofounders of getWiFi/Meshable.
We wanted to make free WiFi simple to find, no app required. We are also bringing free WiFi to small businesses that traditionally do not offer it (e.g. food trucks https://meshable.io/trucks).
Happy to answer any questions! (Follow us at @MeshableHQ <3)
@zhangming086 Try out a sample query such as "philz" into the top left, and when you select the first item you should zoom into the map like so: http://imgur.com/EAWPsxU
You can also scroll around the map using your mouse cursor/scrollwheel.
