Does anyone know of or use a ballistic app for the iphone that is basic.I am new to all of this and not a long range shooter 400 yards max at this time.Something basic and free is what I'm looking for.

We use BulletDrop from the Apple Store and if you upgrade it for a $1 you get unlimited loads you can list. It allows you to adjust velocity, BC, weight, scope height, altitude, conditions, and many more factors and the upgraded version allows you to print a range card. It works really well for us and is dead on when you type in all the correct data.
