FX Pocket Lite

FX Pocket Chrono is the companion app for the FX Pocket Chronograph — a compact Doppler radar device that measures projectile velocity with precision.

Instant Velocity Readings
See your shot velocity the moment it's 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.

Session Statistics
Track your consistency with automatic statistics:
• Average velocity across all shots
• Extreme Spread (ES) — the difference between fastest and slowest
• Standard Deviation (SD) — your shot-to-shot consistency

Shot History
Every shot is logged with its timestamp and velocity. Scroll through your session to review individual shots, identify outliers, or track changes as you tune your setup.

Session Management
Save and review past sessions. Compare your performance across different days, pellet types, or power settings. Each session stores all shots with full statistics.
