FlashStep — Your Badminton Footwork Training Companion Core Features • 6-Point Footwork Training System Covering frontcourt, midcourt, and rearcourt, both forehand and backhand — all 6 key directions on the court. Random flash mode simulates real-game situations to improve your mobility and reaction speed. • Screen Flash for Split Step Before each direction cue, the screen flashes briefly, signaling you to prepare your split step.

Clear visual guidance works perfectly in both portrait and landscape mode. • Adjustable Training Rhythm Customize the interval between cues (1 to 8 seconds).
