About this app

Ballistic Calculator is an accurate ballistic calculator that works fully offline. It is built for long-range shooters, PRS and IPSC competitors and hunters. Your firing solution is ready in seconds — you need no signal at the range.

FREE, AD-SUPPORTED
Every feature is available at no cost, and nothing is locked. A banner ad at the bottom of the screen pays for the app. There is no subscription and there are no in-app purchases — there is nothing to buy.

BUILT ON REAL PHYSICS
Trajectory solved as a point-mass model with 4th-order Runge-Kutta integration and the standard ICAO G1/G7 drag tables. The same modelling approach professional ballistic software uses, in your pocket.

WHAT YOU GET
• A full trajectory table: drop, wind drift, velocity, energy and time of flight at every distance.
• Elevation and windage corrections in MOA, MIL, clicks or centimetres.
• A HUD firing solution: large, readable correction values for the distance you picked.
• Reticle holdover: impact points plotted on a mil-dot, grid or tree reticle.
• A trajectory chart with the transonic zone marked — you see where the bullet is still stable.

BUILT-IN AMMUNITION DATABASE
Over 1600 factory loads (rifle, pistol, magnum, hunting) with the manufacturer's ballistic coefficient and muzzle velocity. Add your own handload in seconds.

ADVANCED CORRECTIONS
• Atmosphere: temperature, pressure, humidity and altitude (air density).
• Wind by clock position, split into head/tail and crosswind components.
• Gyroscopic spin drift and the Coriolis effect at long range.
• Shot angle (Rifleman's Rule) for uphill and downhill shots.
• Powder temperature sensitivity: muzzle velocity adjusted for heat and cold.
• Rifle cant, measured with the phone's sensor.

TRUING — MATCHING THE MODEL TO REALITY
Enter the correction you actually measured at the range and the app calibrates muzzle velocity or ballistic coefficient so the model matches your real drop. Best done at long distance in calm weather.

FIELD TOOLS
• Reticle rangefinder: distance to a target of known size from its angle in MIL/MOA.
• Clinometer: shot angle read from the phone's sensor.
• Compass: azimuth for the Coriolis calculation.
• Distance and azimuth straight from a point on the map.

TRAINING JOURNAL
Log sessions and individual shots. Tap the target where the shot landed (or type X/Y in cm) and the app draws the group, measures its size and tracks your statistics over time: average group, velocity spread, cold-bore shot and barrel life.

WEATHER IMPORT
One tap pulls temperature, pressure and wind for your GPS location and fills in the condition fields (internet is needed only for the download).

SHAREABLE DOPE CARD
Generate a clean image of the correction table for any rifle/ammunition pair and share it: print it, send it to a mate or save it to your gallery.

BACKUP
Rifle profiles, handloads, training sessions and DOPE cards are saved into a single file that survives reinstalling the app.

WORKS OFFLINE • METRIC AND IMPERIAL UNITS • 12 LANGUAGES
Every calculation runs on the device. Switch between metric and imperial units. The interface is available in English, Polish, Finnish, Swedish, Spanish, German, Italian, Czech, French, Norwegian, Russian and Ukrainian.

IMPORTANT
Ballistic Calculator is a support tool for calculations in sport shooting and hunting. Always verify your data at a known distance and strictly follow safe firearm handling rules and local law.
