Need Help

[Lenard]

I am looking for a rather simple program for a smart phone. I like to store info and be able to chaange conditions, namely wind. Since I am shooting to a max. of 600 yards, changing windage by guess, is just that, a guess. I know there are lots of programs available, but prefer the simple ones that allows on the run changes.. Usage is for Rockchuck hunting.

I use Bulletflight when shooting prairie dogs. After you have put in your local temp, altitude and barometric pressure, all you have to do is enter the range and the wind speed & direction. It then gives you the windage and elevation clicks. I use it on an iPhone.
