Tiger Woods launches app
He's definitely got swing: Tiger Woods launches $9.99 iPhone app to help amateur golfers improve their game
He may have dropped to fifth in the world, but he still knows a thing or two about a golf swing.
And now amateur players can access Tiger Woods's expertise straight from the course with a new iPhone app.
The former world number one has launched an application called Tiger Woods: My Swing to give fans mobile lessons in his game.
The $9.99 app, released today, uses video technology to allow players to compare their swing to Woods's.
But it is not yet clear which version of his famed technique they'll see, as Woods is going through his fourth swing change since he turned professional 15 years ago.
He will donate all proceeds from the application to the Tiger Woods Foundation, which promotes youth education.
Woods will act as a virtual teacher on the new app, which is available for the iPhone and the iPod touch from the iTunes store.
