Ogive: Ballistic Calculator

Ogive is a ballistic calculator for long-range shooters, hunters and precision rifle competitors. It computes elevation and windage corrections for any rifle, cartridge and atmospheric condition, then trues them against the impacts you actually measured. WHO IS IT FOR? Long-range and ELR shooters working from 100 yards to beyond two miles. Hunters who need a field holdover corrected for altitude, temperature and shot angle. Competitors building dope cards and truing ballistic data against observed impacts. WHAT DOES IT CALCULATE? Ogive solves the point-mass equation using G1, G7 and custom drag models. It accounts for temperature, pressure, humidity and density altitude; Coriolis and Eotvos effects; spin drift and aerodynamic jump; powder-temperature velocity sensitivity; shot-angle cosine correction; and multi-segment wind with variable speeds and directions. Solutions are given in MOA, MRAD, inches, centimetres or scope clicks. HOW ACCURATE IS IT? The solver is checked against independently published trajectories rather than against itself. At 1000 yards it agrees with Hornady's own calculator to within 0.26 inch, and with Exbal to within 0.4 inch. WHAT IS IN THE DATABASE? 2,505 bullets and 1,943 factory loads, each read from the manufacturer's own published data with the source page and the date recorded against the row. 230 reticle models from Vortex, Nightforce, Leupold, Schmidt & Bender and others. 1,066 scope profiles with click-value calibration. WHAT FIELD TOOLS ARE INCLUDED? An interactive reticle view with computed holdovers at each hash mark. BC and muzzle velocity truing from observed impacts. Moving target lead. Maximum point-blank range. Full trajectory tables with custom range intervals. An Apple Watch companion, a Home Screen widget and Siri shortcuts. DOES IT WORK WITHOUT A SIGNAL? Yes. Every calculation runs on the device. There is no account to create and no network required to solve.
