Before using this when I shot at anything over 100 yards, I would (not too successfully) use the Kentucky windage technique.
I got to the point where I wanted to really understand the science of ballistics and utilize a calculation tool.
So I downloaded this app not really knowing what to expect as many stand alone ballistic calculators are very expensive.
This app blew me away!! It has so many options and settings for a serious shooter; projectiles by diameter, hundreds of factory loads by caliber/brand, you can create custom specs for unlisted ammo or hand loads... The list goes on.
One cool feature I really like is that you can select the yardage interval for the ballistic chart, which comes in handy for subsonic loads that drop drastically over short distances.
It also has a "vital zone radius" option that allows you to basically select how big a target you are shooting so you can know your Point Blank Range for different targets/animals at distance. (Think vital zone of an Elk VS rabbit sized target)
There are so many great functions in this App, Ive had it for 2+ months and am still finding new options. But dont take that to mean overly complex; you can just select your ammo, set the max/min range numbers, and have a fully detailed Ballistics Chart in no time.
One thing that is lacking on this app is a detailed user guide. There are some reviews and explanations online, but they sort of glaze over the main functions of the app. If you want to learn how to use some of the more complex functions of the app, you have to first google what that ballistic terminology means and slowly figure it out on your own. Doesnt stop mean from using it.
But overall GREAT APP!!!
