Hopper

We all need a handy friend who can predict the future (remember That's So Raven?) Hopper is like having an airline psychic in your pocket, predicting the price of tickets to any destination. It will tell you the best time to book and will send you notifications if there are any sudden changes. So you can take that extra $100 and spend it on a hot new vaca outfit. Your Insta followers will be so pleased!
