eBalistyka, developed by o-murphy, is a ballistic trajectory calculator for precision shooters and long-range enthusiasts. The app computes bullet flight paths from user-supplied weapon, ammunition, and environmental inputs to produce aiming data and trajectory readouts. Key capabilities include profile management, guided setup flows, trajectory table generation, and environmental parameter handling. It targets experienced shooters who need mathematically grounded predictions to calibrate equipment and refine long-range shooting technique.

The engine performs physics using a native C++ core and point-mass model

The tool uses a dedicated bclibc C++ engine that executes a 3-DOF point-mass model, and the core accounts for spin drift via RK4 and Euler integration. Users provide initial conditions such as muzzle velocity, ballistic coefficients, and launch angle; the engine integrates those inputs to produce numeric trajectories. This separation of input, numeric integrator, and tabulated output helps users verify intermediate results against external calculations.

Runtime responsiveness is driven by native calculations and a Flutter interface

Calculations run in a native C++ layer, which the developer notes enables faster, mathematically rigorous computation than interpreted code. The user interface is built with Flutter, and the Windows build is available through winget; the project can be compiled for Linux as well. The build choices suggest the app is suitable for desktop workflows that need quick recomputation of multiple trajectories.

Open-source licensing makes the math auditable but the alpha tag demands caution

The tool is published under GPL-3.0, permitting inspection of the physics implementation so shooters and developers can validate formulas and integration methods. The project is in active Alpha, so expect frequent updates and possible breaking changes while features settle. Exportable numeric output provides a persistent record to cross-check predictions against logged range data.

Advanced modeling favors technically minded users over casual operators

Support for multi-BC tables, custom drag curves, and temperature-based muzzle velocity corrections gives the app depth for users who measure their own ballistics or import detailed chronograph data. An SVG-based mil-reticle with live indicators supplies visual aiming cues, which pairs with the numerical engine but requires the user to understand BC selection and velocity calibration to get accurate results.

Practical choice for measured, technically capable shooters; not a plug-and-play solution

The app is a practical option for shooters who need verifiable, high-fidelity trajectory predictions and can manage technical setup and calibration. The active Alpha state and advanced options make it less suited to casual users seeking instant simplicity. A practical tip: verify computed tables against chronograph-derived muzzle velocity and then save calibrated profiles for repeatable accuracy. Recommended.
