Adult entertainment studio Pink Visual today unleashed software that lets people use iPhones to map their sexual exploits.

A test version of the application is available free online to "augment an age-old tradition of boasting about one's sexual conquests," according to Pink product manager Kim Kysar.

The application, named FapMapper, is Web based and not offered at Apple's online App Store, and so it was not vetted by the California maker of iPhone mobile devices. It's "an extension of those conversations guys have with their college buddies after each summer vacation," Ms Kysar said.

"The ones in which they lie like rugs about how many hot chicks they (slept with)...FapMapper is all about adding a visual and geographic element to your sexual exploits, be they real or fabricated."

The application lets people use location-detection features in iPhones to place virtual pins in an online map and then leave comments describing what they did at the spots.

"The comments are at least half the fun," Ms Kysar said.

"We anticipate that for a lot of users, it will be about coming up with the most outrageous claim, paired with the most unlikely location that they can think of."

Someone has already placed a White House pin on the map, according to Pink Visual.

"I'm sure eventually we'll have quite a number of landmarks and historic sites in the mix," Ms Kysar said.

While the software is designed for iPhones, people can create map entries from desktop computers by typing in addresses. Pink Visual plans to tailor the program for other mobile devices.

"We don't want to leave everybody else out of the fun," Ms Kysar said.
