Windage: Ballistics Solver
Long-Range Ballistics Solver
$0.99 · Designed for iPad. Not verified for macOS.
A precision offline ballistics solver: real point-mass trajectory math, G1/G7 drag, a deep bullet library and live reticle holdovers. No account, no signal needed.
Windage is a precision exterior-ballistics solver for long-range shooters, hunters and PRS competitors — built to give you a real firing solution in the field, with no cell signal and no subscription. Every trajectory is computed on your device from a genuine point-mass model and published drag data, so it works on the bench, in the truck and at the mile.
A REAL SOLVER — NOT A LOOKUP
• Point-mass / modified point-mass trajectory integration (RK4), not a canned table
• Standard G1 and G7 drag models, plus G2, G5, G6 and G8, with Mach-by-Mach drag interpolation
• Full environmental model: temperature, station or barometric pressure, humidity, altitude and live density-altitude readout
• Spin drift (Litz), aerodynamic jump, and true Coriolis / Eötvös with latitude and shot azimuth
• Incline (look-angle) shots, powder-temperature muzzle-velocity sensitivity, and gyroscopic stability from the Miller twist rule
• Elevation and windage in MIL or MOA, with velocity, energy, Mach, time of flight and a supersonic / transonic / subsonic flag at every range
A DEEP BUNDLED LIBRARY
• Hundreds of real bullets with measured G1 and G7 ballistic coefficients, sectional density and length — Berger, Hornady, Sierra, Nosler, Lapua, Barnes, Speer and more
• A cartridge reference covering rimfire, centerfire, magnum and match rounds with typical velocities and twist rates
• Tap any bullet or cartridge to load it straight into your profile
RETICLE HOLDOVERS
• A library of reticle subtension maps — mil-dot, MIL and MOA grids, Christmas-tree and BDC designs, first- and second-focal-plane
• See your exact elevation and windage hold drawn live on the reticle from the current solution
• Second-focal-plane subtensions scale correctly with magnification
STANDARD RANGE TABLES
• Physics-computed standard-atmosphere range tables you can browse instantly for any G1 or G7 BC and muzzle velocity — drop in MOA and MIL, 10 mph wind drift, retained velocity and time of flight to 2000 yards
FIELD-READY
• Save unlimited rifle / ammunition profiles
• Build a full range card and export or share it as text
• A tactical, high-contrast dark interface that reads in bright light
• Wind clock, target slider and large dial-ready numbers
PRIVATE AND OFFLINE
Windage never needs a network. There is no account, no login, no cloud round-trip and no tracking. Your profiles, dope and range cards stay on your device. Own it outright.
Windage is an aid for lawful target shooting and hunting. Always verify your zero and confirm your data on paper at distance.
