Imagine not having to ever follow up on another number close. Imagine if every number you got, your phone converted into a date, meetup, or one-night-stand.

Basically, when you take down a number, your phone records the time, date, venue, and allows you to take notes on the interaction. You would be able to record your pre-game, energy level, mood, sobriety level, fashion choices, etc. You would be able to quickly recall the interaction and remember exactly what happened, what she looked like, and what her personality is like.

Furthermore, the algorithms in your smartphone could follow up on your contact and do all the text game for you. By analyzing all your previous interactions, inputs, and results, your phone will calibrate both your personality and her's to put you in the best scenario for a follow up.

This app could be mass marketed as not only a dating app, but also reproduced as a business log book. Just imagine how much more effective you could be if you learned from every interaction.

The social consequences of such an app could be drastic. Sex addicts would no longer have to work as hard to get what they want. "Master pickup artists" would not as likely be able to charge $5k for a boot camp. This whole community would lose its value since would become less dependent on each other and more dependent on technology.

Possible mistakes in the AI and misuse by criminals would lead to the spread of disease, sexual assault, rape, and unwanted babies.
