I use the iStrelok app. I like it a lot. Plus the price is fairly cheap. Lots of reticle choices and it'll show you the POA for whatever distance and magnification that you are shooting.

I have shooter and Ballistic AE...Agree that the latest update for ballistic has made it even. One nice feature of shooter is the ability to true the solution using drop. Great for those of us who haven't made the leap to a chrono yet.
