The popular online reviews service, Yelp, has been ported to the iPhone as an application. If you’re familiar with the online service, you’ll know that Yelp allows you to find, rate, and contribute information to local businesses.

As an iPhone application, Yelp takes advantage of the Core Location feature built into the iPhone OS. It allows you to see the local businesses in relation to your current location and then find directions on how to get there.

Of course, it also allows you to write and see reviews, upload photos, bookmark favorites, see activity from friends, call businesses, and add quick tips. As a nice feature, the iPhone bookmarks sync with your online favorites.

When traveling, or simply trying to find something nearby, the Yelp app excels. It’s fast, works well, and has the right features. Best of all, it is completely free and available for download in the app store.
