REACNAR
React before you think.
Train reflexes using unpredictable reaction stimulus technology. No countdown. No rhythm. No anticipation.
No countdown. No rhythm. Pure reaction.
REACNAR trains reaction speed using random audio triggers with no countdown, no rhythm, and no anticipation. The only variable that matters is you.
An unpredictable audio cue fires with no warning, no countdown, no rhythm.
Tap the moment you perceive the signal — every millisecond is counted.
Your raw reaction is logged, scored for consistency, and ranked globally.
Three modes. One discipline.
One unpredictable cue. One reaction. The purest measure of raw reflex.
Three to seven cues fired in rapid, randomized intervals. Sustain focus under pressure.
Continuous cues over long sessions. Measure consistency, fatigue, and decay.
Try one tick.
Tap to arm. After an unpredictable delay the field detonates. React before you think.
Every tick. Measured.
