## What is KDA Tracker & Joule Calc?

Gear up with the ultimate tactical companion for your next Airsoft or MilSim skirmish! KDA Tracker & Joules is an immersive, dark tactical HUD designed specifically for players who want to calibrate their gear and track their combat telemetry in real time.

KEY FEATURES:

• CHRONOGRAPH & JOULE CALCULATOR
Quickly convert velocity (FPS or m/s) and pellet mass (grams) into Kinetic Energy (Joules). Ensure field safety compliance with localized velocity-to-Joule standards.

• BB WEIGHT PRESETS & CUSTOM INPUTS
Switch instantly between standard BB weights (0.20g, 0.23g, 0.25g, 0.28g, 0.30g, 0.32g, 0.36g, 0.40g, 0.43g, 0.45g, 0.48g, 0.50g) or input custom weights.

• TACTICAL BALLISTICS TELEMETRY (PRO)
Go beyond basic calculations. Simulate aerodynamic drag for 6mm projectiles. Check predicted muzzle velocities, velocity decay charts over distance (up to 60m), and expected Target Flight Time in milliseconds.

• COMBAT DECK OPERATIONAL BOARD
Track kills, deaths, and assists on the fly. Features a giant high-contrast "I'M HIT!" button to increment defeats and trigger an active respawn countdown. 

• MULTI-INTERVAL RESPAWN TIMER
Choose presets from 2m to 60m. Integrates with push notifications to buzz your phone exactly when tactical entry is allowed, keeping your eyes on the field.

• MATCH HISTORY & ARCHIVES
Save skirmish summaries to a local database. Monitor your average KDA, K/D ratio, and overall trend charts. Export logs directly to CSV spreadsheet files.

• MILITARY HUD INTERFACE THEMES
Stay in the zone with our high-contrast, eye-friendly dark design themes. Pick from Stealth Green, Desert Strike, Arctic Frost, or Red Night HUD interfaces.

Whether you are calibrating a replica at the chrono station or fighting on the field, KDA Tracker & Joules puts military-grade telemetry on your wrist and phone.
