While there are a number of things you can do to find the cheapest airfare, timing is everything when it comes to getting the best deals.

Hitlist is a mobile app that knows when it’s least expensive for you to book a flight to your pre-picked destinations, saving you the trouble of regularly checking travel websites. So, if you have a bucket travel list, but also a budget, Hitlist will keep tabs on travel search engines, notifying you when it’s the best time to fly to any of your selected locations. For example, you can create an alert that notifies you if/when flights to Buenos Aires are listed at $650 or less.

Among other customizable features, you can pick the best airport for your travel needs, make your Hitlist public or private, and specify if you’d like to travel only on weekends (or whenever). And there’s also a cool world map to show you all the places you plan to go to or have visited already.
