If you’re a traveler, it can be pretty frustrating to lose your precious interwebz. It can become even worse if you’re depending on it for navigation, leaving you frantically searching for a Wifi hotspot to get back on track.
This is the pain-point that OpenSignal aimed to alleviate when they developed WifiMapper. The purpose of the WifiMapper app is to provide us a mapped database of available, free Wifi hotspots that are nearby. The app works on a global scale and is constantly growing.
As of late, WifiMapper has only been available for iOS. But OpenSignal has been quickly working to bring it to Android. Currently, they are allowing those who are interested to grab a beta version of the Android app.
WifiMapper can also tell you the hotspot’s associated information, such as how the network performs or the type of venue it resides in. It has integration with Foursquare, for contextual information, such as if the coffee is good at that location. Two more features that are in the works are password sharing and offline hotspot maps.
Of course a large part of the database is from crowdsourcing, so make sure to contribute!
