The concept

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.

01
Random tick plays

An unpredictable audio cue fires with no warning, no countdown, no rhythm.

02
User reacts instantly

Tap the moment you perceive the signal — every millisecond is counted.

03
Reaction time recorded

Your raw reaction is logged, scored for consistency, and ranked globally.

Training modes

Three modes. One discipline.

Single Tick

One unpredictable cue. One reaction. The purest measure of raw reflex.

Burst Mode

Three to seven cues fired in rapid, randomized intervals. Sustain focus under pressure.

Endurance Mode

Continuous cues over long sessions. Measure consistency, fatigue, and decay.

Live demo

Try one tick.

Press start. After a random delay the panel will invert. Tap as fast as you can.
