Billboard Releases Chart App

"Our charts are already a huge draw on Billboard.com, whether for music discovery or as a measure of popularity, so it makes sense to apply them to the easy navigation of the iPhone, where users can access them on-the-go," said Editorial Director Bill Werde.

The Billboard Chart App is updated weekly with Billboard's traditional chart release schedule and features each ranking's previous week's position, number of weeks on the chart, and peak chart position. Users can search for specific artists, albums or songs, and search by date.

Ten of the charts are available free of charge, with access to the top 10 positions of those charts, going back three months. These charts include: Hot 100, Billboard 200, Digital Songs, Radio Songs, Dance/Club Play Songs, Latin Albums, Christian Songs, Tastemaker Albums, R&B/Hip-Hop Albums and Ringtones.

For a monthly subscription of $1.99, users can "unlock" the Billboard Chart App for extended chart information including:

An additional five chart genres (R&B/Hip-Hop Songs, Pop Songs, Country Songs, Rock Songs and Rap Songs)
