so usually I have my pick of the week on a Thursday, so I am a day late, and you know why? Cause I have been travelling and haven't been able to get wi-fi. LUCKILY thanks to my picks this week, I have been able to find an open wi-fi connection... Both of these aps do the same thing, they give you information that the airport drop down menu doesn't provide about networks, including signal strength, and security. This can be helpful when theres 10+ networks and you wan't to pick the best open one... Wi-find is a paid program (5 bucks) and changes the drop down menu while air traffic control is a widget, i prefer wi-find but if your to cheap to dish out the few bucks air traffic control does the same thing... I haven't used them a lot but they seem decent and get the job done...
