Ok guys i have played with lots of BC software and i have to say this thing is freaking sweet!!!! I think ExBall is the go to program right now but cost about $70 bucks and can get a little un friendly. Shooter cost $9.99 and is easy mode. Because my phone has gps and weather apps built in i can get temp, humidity, baro pressure, wind speeds, direction, and elevation. when you start the program you can add your rifle specs, twist, height above barrel etc etc then add your bullet(has a butt load of bullets pre loaded sorted by brand, cal, weight). It fills in the BC and you tell it your muzzle fps and it does the rest. For you long range guys it will automaticly adjust for spin drift and coriolis effect. If your scope has mil dots or moa it will range your tagets. If you know your target is X high and is X mils high in your scope = 887 yards then point your phone at the target and it will calculate the angle. hit get solution and presto.. you can get a chart view or graph view. if you have say four or five bullets in 300 winmag it will have them on the grap to and you can see which one will preform better for you. when you get done you can email your charts to who ever in a excel format
