ORLANDO, Fla. -- There is certainly some irony in the timing.
Tiger Woods introduced a new swing application Wednesday when he is in the midst of a fairly significant and highly scrutinized overhaul of his own move to hit a golf ball.
Called "Tiger Woods: My Swing" for the iPhone and iPod Touch (with another version coming for android phones), the application allows users to capture video of their own swings and compare it to positions Woods advocates.
"It's not an instructional piece," Woods said during an interview at the Bay Hill Club, where he begins play Thursday in the Arnold Palmer Invitational. "I give him the lines and the positions I look for. He or she does not have to use that. It's merely a guide. I'm just saying, this is what I use, this is why I use this position, for that reason. It is a guide to help you improve your game."
The cost is $9.99 and all proceeds will go to the Tiger Woods Foundation.
"It's another vehicle for us to gain exposure," Woods said of his foundation, which is funded by three golf tournaments and various other endeavors. "This vehicle didn't exist five years ago."
Woods said the application has been helpful to him as he works through the longest winless streak of his professional career.
His last victory came in November of 2009, and since then Woods parted ways with swing coach Hank Haney and hooked up with Sean Foley last year at the PGA Championship. Since then, nearly every misfire has been analyzed and dissected, and various commentators have weighed in on the pros and cons of what Woods is doing now.
"I can look at a swing I made two months ago. What was the difference between that and now?" Woods said. "There are times for all of us when you hit certain shots and you draw the ball well and can't fade the ball well. Or fade the ball well and can't draw it well. It's instant analysis. It's live. You can do it in practice rounds, pro-ams, on the range before we play. It's a big advantage ... The average golfer gets to use exactly what I've been using, the same technology."
The Arnold Palmer Invitational will provide another interesting gauge for Woods, who won the last two times he played here in 2008 and 2009.
In 13 appearances as a pro, Woods has six victories, but also five finishes of 20th or worse. Aside from the wins, he has just one other top-10, a tie for ninth in 1997.
And since he won here two years ago with a dramatic birdie putt on the 72nd hole, Bay Hill has undergone several changes to greens and bunkers.
"It's going to be one heck of a test this week," he said.
Woods acknowledged the changes he's made in his game under Foley are "bigger" than the ones he made when going from Butch Harmon to Haney. "It's taken a little bit of time."
He called it a "significant" difference from when he first began working with Foley at the PGA.
As for the application, Woods said it fills the void for him when Foley is unavailable.
"Sean is not there each and every day. So how do you know you are improving?" he said. "This is what I do. That's the neat thing about this."
