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. 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 hold overs 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 )! • Correction for coriolis effect • Takes into account temperature of powder (powder sensitivity factor) • Correction for spin drift • Correction for vertical deflection of crosswind • Trajectory validation (truing) by speed or ballistic coefficient • Correction for gyroscopic stability factor • Can measure incline angle with phone camera • Can get current weather (include wind speed and wind direction) from internet for current location and for any place in the world • Supports Imperial (grain, in, yard) and Metric units (gram, mm, meter) • Elevation: Mil-MRAD, MOA, SMOA, Clicks, Inch/Cm, Turret • Get accurate local pressure using internal barometer in iPhone/iPad • Adjusts for atmospheric conditions for current and zero conditions (Density Altitude or Altitude, Pressure, Temperature and Humidity) • Density altitude support (determined automatically for any place in the world) • Ballistics chart (Range, Elevation, Windage, Velocity, Time Of Flight, Energy) • Ballistics graph (Elevation, Velocity, Energy) • Reticle Drop Chart • Range cards • Select target type from big list of targets (80+ available) • Target size presets • Second focal plane scope support • Moving target lead calculation • Fast windspeed/direction adjustment • Integrated with smart sensors. With the tap of a button you can calibrate density altitude, Coriolis, cant and slope in real-time • Unlimited equipment profiles (create own rifles and bullets) • Full history of all your shootings • Scope turret calibration • Rangefinder • Ballistic coefficient calculator • Support Kestrel DROP, Kestrel 5x00, WeatherFlow WEATHERmeter, Skywatch BL, Vectronix, Terrapin X bluetooth devices • Air laboratory (Air Density, Density Altitude, Relative Air Density (RAD), Dew Point, Station Pressure, Saturation Vapor Pressure, Virtual Temperature, Actual Vapor Pressure, Cumulus Cloud Base Height, Dry Air, Dry Air Pressure) • Light/dark/gray color themes • Built-in tutorials PRO Version available: Subscription available for $1.49/month, $9.99/year and provides access to all features. • Your subscription will renew automatically each period.
