NEW YORK -- Sting has launched an app for the iPad, and he's not charging for it.
The singer introduced STING 25 in honor of his 25-year solo career at the Apple store in New York's Upper West Side on Monday.
The "Appumentary" is a digital documentary of Sting's career. It features more than four hours of music videos, concert footage, interviews and more.
Sting said he is releasing it for free "because we don't know how much it's worth."
The app also has video from Sting's 60th birthday party-concert last month at New York's Beacon Theatre, which featured performances with Bruce Springsteen, Stevie Wonder and Lady Gaga.
At Monday's event, Sting performed the song "Fragile," dedicating it to Apple co-founder Steve Jobs and saying, "In some way he's created our future."
