FlashTrainer is a browser-based reaction training tool designed for competitive FPS players who want to improve their flashbang recovery timing. In high-level play, the difference between winning and losing a gunfight after a flash often comes down to milliseconds.
The trainer simulates the blinding white-out effect of a flashbang grenade, followed by a gradual fade-back to normal vision. Your goal is to click at the precise moment your screen fully clears, training your brain to recognize the exact recovery point and react instantly.
Each session consists of five rounds with randomized delays to prevent pattern memorization. After each round you get immediate feedback on your timing accuracy, and at the end of the session you receive a comprehensive performance breakdown with your tier ranking.
Whether you play CS2, Valorant, Rainbow Six, or any other tactical shooter, developing a feel for flash recovery timing gives you a real competitive edge. Practice regularly to build muscle memory and move up from "Keep Practicing" to "Flash Master" tier.
