Ballistica vs Chronverter

Ballistica is a ballistic calculator for long-range shooters who want clear corrections and can see the data behind them. Pick a rifle and a load, enter the line-of-sight range, angle, wind, and conditions, and Ballistica gives you elevation and windage: the direction, the angle, the linear drop or drift, and turret clicks when your scope's click value is set. THE SOLVER • 3D point-mass trajectory model • G1, G5, G7, and G8 drag models, plus custom drag curves • Optional spin drift, Coriolis, and aerodynamic jump • Line-of-sight range and inclined shots • Temperature, pressure, humidity, and altitude, or live conditions from Apple Weather • Station pressure from your iPhone's barometer • Separate conditions for the day you zeroed • Two-stage truing for muzzle velocity and drop scale, with powder temperature taken into account • Warnings for transonic and subsonic flight and for ranges beyond what the model has been checked against CLEAR RESULTS • Elevation and windage in MOA or MRAD, with dial and hold shown side by side • Turret clicks in your scope's own unit, and a warning when a correction exceeds your turret's travel • Linear drop and drift, remaining velocity, Mach, energy, and time of flight • The drag model, ballistic coefficient, velocity source, zero, and truing status are always visible • A clear marker when changed inputs make a solution out of date IN THE FIELD • Stage planner: every target on a stage, in shot order, with a printable wrist card (Pro) • Hit probability for a chosen target size, and which error is costing you the most (Pro) • Measure shot angle and rifle cant with your iPhone • Reticle view with generic MOA and MRAD reticles, including trees with wind dots and second-focal-plane scaling • Optional energy and velocity guidelines for hunting • Trajectory graph for drop, velocity, and energy • Range cards on A4 or Letter, exported as PDF • Mover lead and mil ranging • Widgets, a Lock Screen Live Activity (Pro), and Siri and Shortcuts: ask Siri for your elevation and wind at a given range RIFLES AND LOADS • Rifle and scope profiles with multiple zeros • Custom loads and a built-in bullet library • Import velocity strings from Garmin Xero and LabRadar CSV files, set muzzle velocity from the average, and estimate temperature sensitivity • Share a rifle, load, or saved setup as a file or a QR code • Saved setups for the combinations you use most RANGE SESSIONS • Log observed impacts against the prediction • Group size, mean radius, and average vertical and horizontal offsets • Notes, location, and an optional target photo • Filter by date and rifle, export a session as CSV, or share a summary image YOUR SETTINGS • Metric, Imperial, or mixed units • Daylight, Field Dark, Sunlight, and Low-Light Red themes, or follow the system • Large text, VoiceOver, and Reduce Motion support • iCloud sync and full backups Ballistica Pro is a one-time purchase. There is no subscription and no account.

Chronverter is the essential tool for air gun and airsoft enthusiasts who need fast, accurate ballistics conversions on the field or at the range. Point your chronograph, enter the reading, and instantly see how your muzzle velocity translates across every common ammo weight — all in one clean, tactical interface. What It Does Feed Chronverter a single velocity reading and it calculates the equivalent speed and muzzle energy for every ammo weight you care about, using the industry-standard kinetic energy conversion formula. No more mental math. No more spreadsheets. Key Features - Instant multi-weight conversion — See FPS, M/S, and Joules for all your ammo weights simultaneously in a clean, colour-coded table - FPS & M/S support — Switch between feet-per-second and meters-per-second with a single tap; input and output update instantly - Reference-row highlighting — The weight you measured is highlighted in amber so you can always see your baseline at a glance - Custom ammo weights — Add or remove weights to match your exact loadout; changes are saved automatically - Persistent settings — Your last-used ammo weight, velocity unit, and caliber are remembered between sessions - Caliber tracking — Log your barrel bore diameter in millimeters using the precision stepper or by typing directly - Minimal, high-contrast UI — Designed for bright outdoor conditions with a dark tactical theme and large, readable numbers - Chronograph Link — Connect Chronverter directly to your HT-X3005 or HT-X3006 WiFi chronograph and watch your shots come in live Who It's For - Airsoft players verifying field limits before a game - Air gun shooters comparing pellet performance - Tech players and gun tuners optimizing velocity for different ammo weights - Event referees or marshals performing quick field checks
