Phone app that measures how many calories are burned during sex!

London: A new iPhone app measures how many calories you burn off having sex.

Called the Bedometer, the 59p download analyses the time duration and intensity of each love making session. As for its workings: the gizmo is put on the bed and measures raunchy activity using the iPhone or iPod Touch`s motion sensor before adding up the calories, reports The Sun. App guru Omaid Hiwaizi, of ad agency Chemistry, said: "The Bedometer is the ultimate app as it`s fun and functional." The kinky invention follows the Passion app – an app analyses a user`s bed moves and gives advice on how to improve. ANI
