This is a smart ballistic calculator for long range shooters. It helps shooters calculate hold overs, and scope settings necessary for long range shots. Works with large caliber and airguns. Available for iPhone, iPad, iPod and Apple Watch.
This app is using temperature, altitude, humidity, atmospheric pressure, distance to target, target speed and direction, coriolis effect, slope angle, cant and your rifle configuration for calculate optimal vertical, horizontal and lead corrections.
Features:
• Can use G1, G2, G5, G6, G7, G8, GA, GC, GI, GL, GS, RA4 and even custom drag-functions (built-in editor), and can calculate trajectory without using ballistic coefficient!
• You can select reticle from the list (around 2600 reticles! including reticles from Carl Zeiss, Nightforce Optics, Kahles, Vixen Sport Optics, Premier Reticles, Primary Arms, Schmidt and Bender, SWFA, U.S. Optics, and Vortex Optics) and see holdovers at any magnification (see list of reticles supported here http://jet-lab.org/chairgun-reticles )
• List of bullets: around 4000 cartridges database, more than 2000 bullets database, around 700 G7 ballistic coefficient bullets database, around 500 air rifle pellets database includes American Eagle, Barnes, Black Hills, Federal, Fiocchi, Hornady, Lapua, Norma, Nosler, Remington, Sellier & Bellot, and Winchester (see list of bullet/cartridges supported here http://jet-lab.org/chairgun-cartridges )!

. New feature added: Corrections table for multiple winds and multiple directions. You can find this table on the Ballistic Tables screen - click on the icon in the upper right corner of the screen on the Ballistics tab. You can customize this table however you want: direction angles, direction step, wind speed, wind speed step, correction unit, etc.
