I think what he really needs is a program that detects females of breeding age ( using GPS to work out where he is and using the legal age relevant to that country ).

When one is detected within a kilometer the N900 should start vibrating, and turning the phone the vibration get stronger when it is pointing in the right direction.

And if we add in voice tone recognition the N900 could display a percentage value of how your chat up lines are being received and perhaps offer up better line.

If by some stray chance a woman actually agrees to a union at the physical level, the N900 can send a message to a thread on here declaring that the member has got laid.
