Is there a good shooter app for Iphones

Regular Ballistic and Shooter are the same price (or were 3 months ago) and are very comparable. Unless you need the very advanced aspects of Ballistic AE, you will find that Ballistic offers everything most will need, especially if you've not used a mobile ballistic app yet. Same engine, same data output, same drop charts, etc. for less.

Do a quick App store search for ballistic applications. ;)
 
I use ballistic ae, and have been doing so for a few years now. However, they have complicated the program so much to the point that it is confusing. There are now so many features on it, it feels like adobe photoshop
