Billboard has launched a chart app on the iPhone, aimed at music fans, artists and people in the industry.
The Billboard Chart App features 15 charts from the Hot 100 and Billboard 200, along with genre rankings and ringtones.
Users can view 60 years of chart history, search by artist, album, song, view ranking details, listen to 30 seconds of music and make purchases via iTunes.
“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.
Ten of the charts are available for free, 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.
