If you ever get the chance, explore the world without an agenda. You won't be the same person when you return. Jack Kerouac's book "On the Road" captured the spirit of spontaneous travel -- going where you like, when you like and experiencing the world first-hand. Exploring the globe can be liberating, character-building, and a world of fun. Even more awesome: Today's globetrotter doesn't need to be fabulously well-off to explore almost any country on Earth.
Still, traveling the world isn't free, so unless you're independently wealthy, you're going to need to pinch a penny or two on those trips overseas.
But you have a tool Kerouac never dreamed of: your mobile device. Whether it's a smartphone or a tablet, it's your connection to friends, family and apps that can save you serious cash. Let's look at five budget-stretching apps you should always take along for the ride.
