Any games like SPRUNG (DS) on the iphone? For free

Any games like that? Or like high school and you talk to loads of NPC. Simulation? I think… 10 points for best answer!

What you are looking for is Dating Sim or Visual Novel. Just type either of those into the app store
and you will get a list. Off the top of my head, Cause of Death might be something you would enjoy as well.
