Remember the days before smart phones? No? I don’t want to either.

Your iPhone can be your very best travel friend when you’re in a strange and mysterious place. 

Here are 10 travel apps you should check out. Some we can’t live without.

FlightBoard - $3.99

I know what you’re thinking. $4 for an app?! Well, if it’s any consolation it’s not the most expensive app for flight info. It’s robust, fast, simple, and easy to use. BTW. The interface is based on the Charles de Gaulle airport.

Packing Pro - $2.99

Ever board a plane and think, “Crap! I forgot my bathing suit!” Well, that’s why apps like Packing were made. To help you make sure you’ve got everything and won’t leave anything behind. Featured on Travel + Leisure, CNN, and National Geographic, this app also comes with sample packing lists to help you out based on the type of trip you’re taking.

 Lonely Planet Travel Guides - $5.99

Lonely Planet has a travel guide for pretty much any city you’re going to. Most of them are highly rated and are a God-send for travelers. They’re a wonderful addition if you’re going to a place that may not speak your language or if you’re on a tight schedule and prefer not to wander around aimlessly.

XE Currency - Free

Love this app. XE Currency has live charts and will constantly grab the latest rates for you. The best part is that this app stores the latest rates so it works even when you’re not around WiFI or 3G. Never get ripped off by a money changer again.

Instagram - Free

You probably already have this app installed but just in case, we’re going to remind you again. Take beautiful photos wherever you are, geotag them, and make your friends jealous as you travel into gorgeous and exotic locations.
