So, recently I have discovered a great app for my iPhone 6 Plus.
I've always used a VPN when on public wifi and even when at work. Since there are so many vulnerabilities on public wifi, it seems like the best solution. However, the big flaw is in switching it on and off. I rarely would remember to turn it on at Starbucks, then if I left (and switched to LTE) and went back it would be disconnected. Pain in the ass.
