Metromix LLC has launched the newest version of its What's Nearby  iPhone application, letting users find nearby entertainment options based on their GPS position.

The Metromix?s free social-planning application lets consumers locate restaurants, bars and clubs, events and music, as well as movie theaters and showtimes within walking distance or a short drive away from their current location. Already downloaded more than 100,000 times, What's Nearby also gives Metromix's 4 million monthly users, who are located across 37 United States markets, the ability to post reviews and photos to Metromix.com using their iPhone and share those submissions on Facebook using Facebook Connect.

?We know that Metromix.com is the first place young adults go to find out where to go and what to do in their city, which is why we created the What?s Nearby application,? said Sean Smyth, director of marketing and development at Metromix.com, Chicago. ?We want to offer a convenient and at-your-fingertips way for people who are on the go to find fun things to do when they are out and about.

?This feature is a great timesaver and allows people to spend less time planning and more time out having fun with their friends,? he said.

?It also helps users streamline sharing of information through the application by posting reviews and photos not only on Metromix.com, but also their personal Facebook page.?

Metromix was formed through a joint venture between Gannett Co. Inc. and Tribune Co., two of the country's largest media companies with newspapers, television stations and Web sites in the nation's top markets.

Metromix is currently operating in 37 major markets throughout the U.S., including Chicago, New York and Los Angeles, and is expanding into additional top markets by the end of the year.

Metromix?s national network of local entertainment Web sites target 21-to-34-year-olds and provide information on where to go and what to do.

?This group of adults is obviously very tied into social media trends and are most likely the ones interested in downloading our What?s Nearby iPhone application, since it allows them to share information across a variety of communication channels including our Web site and Facebook,? Mr. Smyth said.

The network currently generates more than 60 million monthly page-views.

Additional features of the What's Nearby iPhone application include the Buzz, featuring the latest up-to-the-minute photos and reviews from users all over the user?s city.

When a user wants to discover something new, the application?s Magic Shaker feature provides a randomly selected nearby venue to check out with a shake of the iPhone.

Flexible Search lets users search by keywords like ITALIAN or SUSHI or filter results in categories such as restaurants, bars and events by type, price and user rating.

Metromix?s third-party partnerships including restaurant reservations provided by OpenTable, restaurant-takeout-ordering provided by GrubHub, movie-ticket-purchasing provided by Fandango and maps provided by Google.

To download Metromix's What's Nearby iPhone application, iPhone and iPod Touch users can search for METROMIX within the iTunes App Store on their devices.

The featured venues on Metromix.com are a combination of what Metromix?s users and editorial staff feel are the best ones in the local market.

?That?s what Metromix.com is all about: providing users with a balance of expert editorial content and the opportunity to weigh and share what they feel are the most worthwhile and entertaining spots throughout their city,? Mr. Smyth said.

?The What?s Nearby application is free for our users and all the venues featured on the application are listed for free,? he said.

?We want to help our users get the most out of their social time, which is why we?ve made What?s Nearby free to anyone through the iTunes App Store."

Metromix is using various channels to get the word out about its iPhone application.

?Wherever we have a touch point with our users, we are marketing and promoting the application,? Mr. Smyth said.

?For example, we are promoting it front and center on Metromix.com, our Facebook pages, Twitter feeds and through traditional media channels like TV and print with our local market media affiliates,? he said.
