Skyscanner

If you have ever planned a trip, you know that you need to consult lots of apps and websites to take care of every aspect. You use one app to book a flight, another to book the hotel, and so on. The Skyscanner app promises to bring all of these features together, under the same umbrella.
 
With Skyscanner, users will be able to get the cheapest flights possible to their destination, get price alerts for certain routes, get inspiration for new destination by following suggestions, search for hotels that match your preferences, look for places to rent a car, and you can even pick up a search that you’ve made at an earlier date.
 
The developers also say that the application doesn’t have any kind of hidden fees or charges, not to mention the fact that you can also gather those important frequent flyers miles.
