Zeroing Ballistics app for iPhone and iPad

Save time and money as you zero in your rifle in 4 shots with GunSim Rifle Zero Ballistics. The app simply tells you how many clicks to adjust your scope, based on your initial group.
Left and Right, Up and Down are clear, no need to guess!
The GunSim ballistics engine lets you zero your rifle for 200 yards with the target at 25 yards (or any other distances), so you can see the holes, again saving time and money.
You can save your numbers for later, to remind you what your zero is.
1/2 Moa, 1/4 Moa, 1/8 Moa, 1/10 Mil, USA/Metric all included. G1/G7 BC values.
