If you hate ads like I do then this app is for you. Its not perfect as its has its flaws but if you take in consideration the limitations of iOS this is the closest this to a PERFECT ad free experience on your phone. They install a fake VPN profile to bypass the "WiFi only" limitation but without routing your traffic through VPN servers. It definitely works (at least on iPhone 6 Plus S). Why 4 stars?! Well! It definitely has it flaws. It takes a second or two for the VPN icon to appear and until that shows up you cannot connect to Internet. A worthy trade off for me because I hate ads. P.S. 4 stars only so I can get the author of the app to improve it. P.S.P.S. This is definitely worth 5 STARS
