I am also looking for a good app for my IPhone 5S and am seriously looking at FunGolf. You can try it for free for a trial and pay $19.99 one time if you like it. No additional costs after that. It has a 3D screen shot which is unique and loaded with a bunch of extra features. I have contacted them with some questions and they seem pretty friendly and responsive. You can take a look at it on there website www.fungolf.com.
