Hopper This app tells you when you’ll get the cheapest flight to your destination, then lets you book it from your phone. Select your preferred date range and destination and Hopper will indicate whether to BUY or to WAIT. It’ll even keep an eye on prices for you, notifying you when they’re at their best. The app developers say their data-science team has analyzed trillions of flight prices in their historical archive to pinpoint trends. However it works, it works — on iOS and Android. Hopper.com
