Yelp has released an update to its social city guide application adding German localization and integration with Facebook Places. Yelp for the iPhone and iPod touch is a companion app for the popular online service of the same name, allowing users to search for nearby businesses such as bars, restaurants, gas stations and more based on factors such as location, hours, distance and price. Users can add photos and reviews to any business location and read the reviews and posts left by others when browsing and searching for venues. The latest update adds German language support and now allows users to view their friends’ Facebook check-ins directly within the Yelp app. Yelp is available from the App Store as a free download.
