When it comes to adventure and travel, who could possibly know more than National Geographic Adventure magazine?
The magazine's website has regular features about techie toys and tools, so it was no surprise that blogger Steve Casimiro would write a post featuring his choices for the top twenty travel apps for iPhone. Some of his choices, such as HearPlanet, FlightTrack Pro, the Lonely Planet Phrasebooks, and World Customs [clicks open iTunes] aren't surprising, while others (Packing, Room) are interesting apps I wouldn't have even thought to try.
Of course, all of us have our own favorite travel apps. I couldn't imagine going on a trip anywhere in the world without Geocaching, and I like the free TripIt app better than the one that comes with FlightTrack Pro. I now have Brushes with me everywhere I go to capture quick sketches, and what's travel photography without being able to take panorama shots with Pano or 3D pictures with 3D Camera?
What are some of the apps that you can't live without when you're traveling? Leave your comment below.
