The free application allows travelers to search for popular hotels, restaurants and attractions, as well as find the cheapest airfares available. The application is available in 13 different languages, giving travelers around the globe a localized TripAdvisor experience.

“Our iPhone app gives people in 20 countries and 13 languages a new way to access the more than 35 million traveler reviews and opinions available on TripAdvisor,” said Steve Kaufer, founder and CEO of TripAdvisor. “Now, travelers can find a great hotel, restaurant or attraction and book a cheap flight whether they’re at home or on the go.”

The new TripAdvisor iPhone application, which replaces Local Picks in the App Store, uses the iPhone’s GPS capabilities to allow travelers to search for nearby hotels, restaurants and attractions. With the tap of a finger, users may sort by rating, distance and price. Travelers can also send in reviews while they’re on the road and their experiences are still fresh.

Additionally, travelers can use TripAdvisor Flights, the site’s flight search engine, to find the cheapest airfares using their iPhone. They can shop a comprehensive selection of flight choices across the most popular online travel agencies and airlines.

TripAdvisor’s free application is available to iPhone and iPod touch users in 20 countries across North America, Europe, South America and the Asia-Pacific region beginning today on the App Store.
