Hopper is a new kind of travel company that uses big data to empower travelers. The Hopper app for iOS and Android analyzes trillions of past and current trips to predict when you should fly and buy. The app notifies you when fares drop so you can book flights at just the right moment. Hopper is among the fastest growing travel apps ever, with over 10 million installs since it was launched in 2015.
