App Name: BD-Engine
Subtitle: Wireless Ballistic Calculator
Description:
BD-Engine is a professional ballistic calculator that connects wirelessly to the BD-Engine hardware module via Bluetooth Low Energy, delivering real-time, high-precision trajectory computation.
Built for precision shooters, BD-Engine provides fast and accurate firing solutions with the power of a dedicated solver and the simplicity of a mobile app.
Key Features:
Instant Wireless Pairing — Connect to the BD-Engine module over BLE in seconds. Auto-reconnect remembers your last device.
3DOF Ballistic Solver — Advanced three-degree-of-freedom trajectory computation for accuracy at any range.
G1 & G7 Drag Models — Supports both industry-standard drag functions for precise bullet matching across all common calibers.
Full Environment Setup — Temperature, pressure, humidity, altitude, wind speed and direction, shooting angle, and muzzle cant — all at your fingertips.
Real-Time Trajectory Table — View drop, windage, velocity, and time-of-flight at every range increment. Verify your zero with a dedicated check distance.
Custom Bullet Profiles — Configure caliber, weight, ballistic coefficient, and twist rate for your exact load.
Dual Unit System — Toggle between metric and imperial units on the fly.
Standalone Operation — Once configured, the hardware module computes trajectories independently — no phone required for firing solutions.
BD-Engine combines dedicated ballistic hardware with an intuitive iPhone interface for shooters who demand precision.
Note: Requires a device equipped with the BD-Engine BLE hardware module (sold separately).
