About this app
BalTrak -- Ballistic Tracker
Professional ballistic calculator for shooters and hunters.
★ WHAT IT DOES
• Precise external ballistics — G1 (McCoy) and G7 (Litz) drag models
• Euler integration with 0.2 ms step, up to 2000 m range
• Air density correction (temperature, pressure, humidity)
• Coriolis and Eötvös (vertical azimuth-dependent component)
• Spin drift (Litz empirical formula)
• Trueing — automatic BC correction from field measurements
• Chrono log — log measured v₀ readings (Garmin Xero, LabRadar,
MagnetoSpeed, ProChrono); the app computes average, sample SD
(n−1, Bessel) and ES live; a single switch overrides the factory
v₀ with your measured average
★ BULLET LIBRARY
• 82 built-in bullets across 15 calibers (Lapua, Hornady, Sierra,
Berger, Nosler, Federal, Winchester, CCI, Eley, RWS)
• Custom bullets supported (add/edit/delete, JSON import-export)
★ SHOOTING PROFILES
• 14 preset setups (rifle + optic + bullet) for main calibers:
.22 LR, .223 Rem, 6mm/6.5 Creedmoor, .260 Rem, .308 Win, .30-06,
7mm Rem Mag, .300 Win Mag, .338 Lapua, 9mm, .45 ACP
• Create custom profiles: rifle, optic, sight height, zero range,
click unit (MIL/MOA), click value, twist, SG, BC correction
• Profile = complete calculation state: selecting a profile loads
every parameter (incl. caliber filter) and auto-enables spin drift
if SG > 0
• Smart sync detection: if you manually change any parameter that
belongs to the active profile, the profile is automatically
unselected — no ambiguity about "is this still my profile?"
★ RESULT DISPLAY
• Turret dial (default) — round scope turret with dots for each
distance at its actual click angle; ideal for quick dialing
• Dope card — distance list with exact up/down click counts
• Traditional trajectory curve (fl_chart)
• Detailed table: velocity, energy, time of flight, drop, POI,
MOA, MIL, clicks, wind, velocity retention %
★ EXPORT & INTEROPERABILITY
• PDF — branded A4 sheet with trajectory table for print or phone
• CSV bullet profile — one row with rifle, optic, zero, BC G1/G7,
V0, twist, click unit/value and atmospheric reference (SI and
imperial side-by-side, so mapping in other apps works without
unit conversion)
• CSV dope card — range table: distance, velocity, energy, drop,
MOA, MIL, clicks, wind — one row per computed distance
• JSON — import/export your custom bullets (share with others)
Compatibility (honest):
• Strelok Pro, Shooter, iBallistics, Hornady 4DOF — direct CSV
import via their "Import CSV" + map-fields wizard.
• Kestrel 5700 Elite, Garmin Tactix, Applied Ballistics devices do
NOT import CSV directly. The workflow is two-step: first into
Applied Ballistics Analytics (Gun Profiles → Import CSV → map
fields), then Bluetooth sync to the device.
• Garmin Xero C1 Pro is a chronograph, not a ballistic solver — it
does not import profiles (CSV can feed Garmin Connect →
Tactix/Fēnix ballistics module, not the Xero itself).
★ TECHNICAL
• Three languages: Slovenian, English, German, Italian, Czech
• Live recalc — graph/table/turret update on every parameter change
• Works fully offline
• Data stays on device (SQLite database)
• Built-in manual in all three languages: full theory, bullet
library, profile reference, chrono log and trueing — also offline
★ DISCLAIMER
Calculations are mathematical simulations. Real-world results always
require field verification. The user is responsible for safe and
lawful handling of firearms and compliance with local regulations.
