Applications geared towards travelers are fast becoming the most popular programs you can install on your phone.  Whether it's the iPhone, Blackberry, Palm or even Windows Phones, there is an app for you.

“To me, the most valuable thing is you have all this itinerary information in one place, and it’s easy to get to,” said Pete Davies, who travels several times a year for his job at a clean technology company. “A year ago, I would carry a whole sheaf of printouts and confirmations with me, and now I have them in one simple place.”

Tools like iReceipt allow travelers to store and organize receipts for expense reporting, reducing the number of hard copies that need to be shuttled around on a trip.

Location-based apps use GPS technology to give users information about restaurants, tourist attractions and even taxi services in their immediate vicinity. Some, like Urbanspoon, focus exclusively on restaurants; others, like Yelp and Google Maps, offer information about everything from dry cleaners to coffee shops. Some also include user reviews.
