Businesses -- as well as musicians, athletes, celebrities and brand owners -- can build, engage and monetize their fan base using Fan Appz, a suite of tools built for fans and fan pages. Managers of fan pages can use the apps to create Top 5 rankings, polls, quizzes and gift applications to engage and grow their fan base. Fans can discover the newest fashions, gadgets, trends, popular culture and content from their favorite companies, performers or artists on Facebook. The standard app is free; the professional version costs $50 a month, and includes fan page promotions and coupons, as well as video support for quizzes and polls. About 578,000 people use the app each month. The professional version of Fan Appz also eliminates ads.
