iOS/Android/Web: Airport Wi-Fi isn't always easy. Depending on the airport and the terminal, you might be hard pressed to find a decent spot to access the internet. This interactive map can help — it locates free Wi-Fi and Wi-Fi passwords at airports around the world. WiFox, an app built by computer security engineer Anil Polat, pinpoints free Wi-Fi spots and passwords at 127 airports worldwide. You simply browse the app to find your airport, and then you can tap wireless icons to see more information or look at a listview by airport. While the iPhone and Android apps are $2.99, the web app is free. According to the app's description:
WiFox is a continually updated map of airport and lounge wifi passwords from around the world. In map view, you can tap any wifi icon where wireless information is available, and use the button to copy the password to the clipboard. The map is available offline so you don't need an Internet connection to use WiFox when you're travelling.
Users can add passwords to the app, too. They're sent to Polat for verification and approval before they're added to the map. You can check out the web version here and download the apps at the link below.
