Full description

BD-Engine serves as a fully standalone offline ballistic calculator designed for trajectory calculation. All computational logic runs locally on your iPhone, requiring no external laser rangefinders or matching peripheral devices. Users can input core ballistic parameters to obtain accurate trajectory data via mature professional formulas without network access. Suitable for enthusiasts to conduct daily ballistic parameter verification and trajectory simulation. The app abandons all hardware linkage functions to deliver lightweight and stable computing performance, focusing purely on formula-based ballistics computation and offline data analysis.
