You would never leave for a trip without your passport and your boarding pass, but your iPhone is about to become the next must-have item for frequent travelers. There are a number of apps that make travelling easier and more organized, and many of them are completely free of charge. Here are just three of the best apps for jetsetters:

Just Landed
If you frequently pick up other people from the airport, Just Landed is an app that will help you to keep all of your friends’ or family members’ flight information in one easy-to-access place. The app’s clean, beautiful interface offers frequently updated information about the person’s flight, reminds you when it’s time to leave for the airport and even texts your loved one to tell them when you’re arriving.

Currency
Travelling internationally means a lot of complicated currency exchanges, but this smart app will make the process a bit easier. Currency provides the latest exchange rates between just about any countries in the world, and it also includes a handy calculator that will help you to calculate an item’s worth while on the fly.

GateGuru
Manage every part of your travel plans with this simple, colorful app. GateGuru is one of the only travel apps that offers push notifications for changes in flight times, as well as estimated TSA security wait times and full airport maps.
