Buzzd Aggregates Check-Ins From Foursquare, Gowalla And Others In Social City Guide

We’ve written about the social city and nightlife mobile app, buzzd, which pulls its data from Twitter and other buzzd users, for a bigger picture of the places that are hot in a given location. The startup just released an Android app in December and today is launching a new version of its iPhone and BlackBerry apps that integrates location-based services in the mix.

The buzzd network compiles information from its base of over a half-million users, Twitter, and other real-time sources to provide users with activity updates for almost half a million venues across the United States, the U.K. and Canada. You download the app and it will bring up a list of venues close to you that are currently popular based on people talking about them on Twitter and Buzzd. And the app now aggregates over 500,000 check-ins per day from Twitter, Foursquare, Gowalla, Brightkite, Loopt, Yelp, Whrrl and many other real-time location -based services sources to present activity at bars, clubs, restaurants and other points of interest. The new data will be added to the app’s “buzzdmeter,” which gives you a real-time measure of activity at popular bars, restaurants and nightclubs in your city.

The integration with these services makes a lot of sense for Buzzd, as the app essentially tells you where the most frequented places are within your location. As Foursquare, Gowalla and other location-based social networks continue to attract more users, these services increasingly provide a comprehensive way to see where your social graph

With the new versions of the apps, users can now find their Facebook friends and Twitter followers on buzzd as well as simultaneously post their buzzd ratings to their Facebook wall and/or Twitter feed. And users can see what their friends are up to in the new “feed” section. Buzzd has also created a rewards program to encourage more people t broadcast their ratings of venues to friends.

Currently, Buzzd is tracking over one million active users/month across its apps, which is solid growth for a niche app that was only released a year ago. Buzzd originally launched an app on the BlackBerry as one of the original BlackBerry Partners Fund recipients. While the startup is expanding to the iPhone and Android platforms, Buzzd is also adding nifty features, which should help increase its userbase.
