If you are looking for Otome games, or like dating simulations for the itouch, ipad, or iphone, here are some games:

*Shall we date?: My sweet prince
*Shall we date?: Ninja Love
*Shall we date?: Actor to be
*Shall we date?: Konkatsu
*Shall we date?: Heian Love
*Pirates in Love
*Flower Shop
*Pinky Distoration
*PureLove

I am not sure if there are more but these are the ones i know of. I hope this helps with that, and later i will be able to give some walkthroughs for some of these games!
