Instant Velocity Readings
See your shot velocity the moment it is fired. The app connects wirelessly via Bluetooth to your FX Pocket Chronograph and displays readings in real time. Toggle between feet per second (fps) and meters per second (m/s) with a single tap.

Energy Calculations
Know the impact energy of every shot. Enter your projectile weight and the app automatically calculates kinetic energy in foot-pounds (ft-lbs) or joules. Perfect for tuning your airgun or verifying compliance with field limits.
