A new iPhone application uses GPS technology to literally track its user's movements - bowel movements, that is.

For $1.99, Poop The World lets users keep - and share - a bathroom journal, including the shape, smell and location of their daily business.

It's the brainchild of Vancouver resident Tim Yewchuk. Yewchuk says the idea struck him when he realized most of the people he knows tote their phones to the john with them.

"I did sort of a survey of my hockey team, and it turned out 99 per cent of them were their iPhones while going to the bathroom," Yewchuk said.

"I thought, this is it. Gold mine right here."

The idea was developed by Vancouver-based Atimi Software, Inc. The company has created applications for The New York Times, Mastercard, Johnson and Johnson, NBC and Donna Karen. In fact, vice president Scott Michaels says iPhone applications now make up half their business.

"It went from zero per cent of our business to 50 per cent of our business easily within one calendar year," Michaels said.

Yewchuk says he took a loan out on his house to pay Atimi Software to realize his dream application -- and if he can sell about 45,000 more units, his investment won't go down the toilet.
