Hopper

Hopper is an app that helps you find flights at the best prices. Using Hopper is easy: all you have to do is to choose your departure city and your destination. Then, you'll see a calendar with all the dates colored by price" the green dates are the cheapest ones and the red and most expensive.

However, the true magic doesn't lie in the fact that you can view the prices of a flight on a certain date. Nope. What makes Hopper so interesting is that it includes a 'forecast' tool that suggests if you should actually buy the ticket or if you should wait a little longer.

Hopper is a flight purchasing app that's really useful. You can save a good chunk of money and all you need is a little luck and patience. The interface is simple and sleek, so you can start using it and monitoring your flights instantly. Just make sure that you activate the notifications in order to be notified when you should purchase your flights.
