Want to measure your performance in the sack? Well, all you need to do is to download a new iPhone application and see how competent you are when it comes to action between the sheets

The ‘‘Passion’’ application uses the phone’s built-in accelerometer, used to sense motion, as well as the device’s microphone and timer.

Users will just have to place the phone on the bed or in a pocket before intercourse and, at the end of the horizontal dance, the phone will give a rating out of 10 based on three criteria—duration, orgasm and activity.

The timer measures duration, while the accelerometer measures activity and the microphone measures the orgasm.

And then one can uploaded the scores and compare to those of other people around the world.

In fact, ‘‘high scores’’ leaderboard also gives you a chance to go on a bragging drive.

The application is the brainchild of Chris Alvares, a US computer science student who has previously developed a number of smartphone quiz apps.

‘‘All you have to do is start the application, put your phone on the bed, in an arm band, or even in your pocket and have intercourse, it is as easy as that,’’ the a major newspaper quoted Alvares as saying in a blog post announcing the new app.

He added: ‘‘Once you are finished, press the stop button and view your results.’’

In case a person is not happy with the score, there is an option of ‘‘try again’’, providing a chance for another stint in the bed.

In an email interview, Alvares said that he was not sure how many copies of the app he had sold yet.

‘‘No, it is not a hoax, and it actually works! The idea came up as a joke between some of my co-works [sic] and I, and later I figured out an algorithm that I could use with the phone’s available features,’’ he wrote.
