Tactical Ballistics

A complete long-range shooting solver that runs 100% offline.

No account, no sign-up, no tracking, no subscription — every solution is computed on your device and nothing leaves it. Built on a real RK4 trajectory engine with canonical G1/G7 drag and custom Cd(Mach) curves, not a lookup table.

About the project

Tactical Ballistics is an independent, offline-first long-range shooting solver. At its core is a from-scratch RK4 trajectory engine — canonical G1/G7 drag, custom Cd(Mach) curves, spin drift, Coriolis, aero jump, and powder-temperature and barrel-length corrections — validated against established solvers (py-ballisticcalc, JBM, Hornady 4DOF).

Every solution is computed on your device. No account, no network round-trip for a shot, no analytics SDKs, no ads — the app works fully in airplane mode. The aim is a tool serious enough to trust on the clock and simple enough to use in the field.

Calculator screen — Calculator — profile, range and a live firing solution.

Firing solution — Drop, drift, MIL/MOA and turret clicks at a glance.

Trajectory chart — Full trajectory as a table or a drop / wind / velocity chart.

Reticle visualization — Reticle view with the computed hold marker.

Range card — Printable MIL / MOA range card.

Stadia rangefinder — range a known-size target through the reticle.

Ballistic solutions are a starting point — always confirm and true your DOPE on a known-distance range. Follow all firearm-safety rules and your local laws.
