Reflexa: Reaction Time Test

Reaction time test and reflex trainer: measure your reaction speed in milliseconds, compare it with the ~273 ms public median, and train to get faster. Free to start.

How fast are you, really? Reflexa gives you the number in five seconds — and a plan to beat it.

▸ TAKE THE REACTION TIME TEST
The classic green-flash test, done right on your phone. Wait for green, tap. Your result appears instantly in milliseconds with your tier — Lightning, Nice Reflex, Average or Room to Grow — and where you land against the median of millions of public reaction tests. Timing runs on your device, so there is no mouse or browser latency inflating your score.

▸ WHAT IS A GOOD REACTION TIME?
• Under 200 ms — lightning: the range of competitive gamers and athletes
• 200–250 ms — a genuinely fast reflex
• ~273 ms — the public median most people land around
• 300 ms and above — plenty of headroom, and the fastest gains
Reaction time peaks in your twenties and slows with age, fatigue and lack of sleep. It also improves with practice.

▸ 60 REFLEX CHALLENGES, 15 MECHANICS
Reaction speed is not one skill. Reflexa trains every kind:

Can reaction time be trained? Yes. Short, consistent practice measurably shortens it; Reflexa keeps your baseline and every session so the gain is visible, not imagined.
Is a phone test accurate? Reflexa measures on-device with the same method every time, so your results are consistent and comparable day after day.
Is it free? The reaction test, Easy challenges, the daily run and your history are free. Pro unlocks the rest.
