I have about 100 apps installed on my iPhone 5c but none as useful as the Free Wi-Fi Finder app that I downloaded over the weekend.
The Free Wi-Fi Finder uses your current location to display where there is Wi-Fi available nearby. Results can then be filtered by location type such as Bar, Hotel, Library, Restaurant or School/University. When you select the hotspot you want to use, it displays the locations details and the option to get directions to that location.
There is also the option to add location information for new Wi-Fi hotspots to the apps database. The app already features over 550,000 free and paid Wi-Fi locations in 144 countries worldwide
