Record shooting, calculate ballistics, manage assets.
The app records target and range shooting, calculates ballistics, and manages shooting assets like guns, ammo, and components. It calculates group size, average distance to center, velocity statistics, and recommended turret adjustments for targets.
Calculates air volume, pressure loss, velocity, and duct size for rectangular or round ducts. Supports both imperial and metric units. Users input values to determine required dimensions and system performance.
The app provides HVAC duct sizing using ACCA's Manual D, the ANSI standard for residential duct design. It offers features like zooming, locking the wheel, and taking snapshots for reference.
Calculate bullet trajectories using a Modified Point Mass Solution with 4 Degrees Of Freedom. Input ballistic coefficients or drag coefficients from Doppler radar analysis. Adjust for wind, elevation, and distance.
Meter detects and records seismic waves from earthquakes, volcanic eruptions, and other vibrations. It uses the phone's accelerometer to measure and analyze motion. Displays a graph of ground movement over time. Allows users to save and review data.
The app monitors pitch velocity, keeps score, and tracks the count during baseball games. It is suitable for use at any level of baseball, from little league to major league.
Convert vibration units including velocity, acceleration, and displacement. Switch between Hz and CPM for frequency. Convert displacement between mils and microns with options for RMS, 0-peak, and peak-peak.
