AURA Reflex — free reaction time test and reflex trainer
AURA Reflex is a free browser tool that measures reaction time and trains it with six short drills. F1 Lights reproduces a Formula 1 start: five red lights come on one per second, hold for a random 0.2 to 3 seconds and go out, and you tap as fast as you can; a tap before the lights go out is a jump start and voids the attempt, and five valid attempts give an average, a best and a consistency figure. Audio Start is the same test with a tone instead of lights, the auditory reaction a sprinter or swimmer needs at the gun. Choice reaction shows an arrow in the middle of the arena and you tap the side it points to, sixteen times, so decision speed is measured together with movement. Target Rush is thirty seconds of coloured circles popping up at random positions, scored on how fast each one is tapped, with ten levels that shrink the circles and shorten their lifetime. Go/No-Go uses the same arena but only green circles may be tapped, so it trains the ability to withhold a response as much as speed. The Schulte grid is a 4x4 or 5x5 table of numbers to tap in order, a classic visual-search and peripheral-vision exercise used in sports vision training. Every day one drill becomes the daily challenge with a seeded course that is identical for everyone, a streak counter and its own board. The five skills feed a Reflex Score from 0 to 100 with a radar of reaction, decision, precision, control and search. Times are measured on the device between the stimulus and the touch, so the numbers also reflect your screen and input latency, which is why the tool compares you with yourself first: personal bests, a sparkline of the last thirty sessions and a training level per drill are kept on the device with no account. Signed-in users additionally get rows on the daily and all-time leaderboards. It is a training and entertainment tool, not a clinical or neurological test.
Why use AURA Reflex — Reaction Time Test
F1 Lights and Audio Start for simple reaction time, Choice for decision speed, Target Rush for eye-hand coordination, Go/No-Go for inhibitory control and the Schulte grid for visual search. Each has its own personal best and level.
One drill a day, the same seeded course for everyone, a streak that counts consecutive days and a board that resets at midnight UTC. A reason to come back for two minutes.
Your personal bests become one number from 0 to 100 and a five-axis radar, so you see which skill is lagging instead of one average that hides it.
Guests play with full stats kept on the device. A free account adds daily and all-time leaderboards per drill. No AuraCoins are paid for reflex sessions.
How to test your reaction time with AURA Reflex
- 1
Pick a drill or the daily challenge
F1 Lights or Audio Start for a classic reaction test, Choice for decision speed, Target Rush for eye-hand speed, Go/No-Go for control, Schulte grid for visual search. The daily card at the top starts the shared course of the day course.
- 2
Tap the arena to start
Wait for the lights or the tone, then tap anywhere; in Choice tap the side the arrow points to; in the target drills tap each circle the moment it appears and leave the red ones alone; in the grid tap the numbers in order.
- 3
Read the result
Average and best time in milliseconds or points, consistency, accuracy where it applies, a band from warm-up to F1-driver reflexes, and your rank on the board of the day if you are signed in. A gold badge marks a personal best.

Train, then compare
Repeat a drill a few times a week, play the daily challenge to keep the streak and watch the Reflex Score and its radar. Sign in to keep your levels across devices and to join the leaderboards.
Frequently asked questions
Is the reaction time test free?
Yes. All six drills, the ten levels, the daily challenge and the personal statistics work without an account or download. A free account is only needed for the leaderboards.
What is a good reaction time?
For a simple visual stimulus most adults average around 250 milliseconds on a phone or laptop; consistently under 200 ms is very fast. The tool labels bands from warm-up to F1-driver reflexes as motivation, but the meaningful comparison is with your own previous sessions on the same device.
What is the Schulte grid for?
It is a classic visual-search exercise: a table of shuffled numbers you tap in order. It trains scanning speed and peripheral vision, and from level 8 the numbers reshuffle after every tap so memory cannot replace search.
Why does my time change between devices?
The measurement runs on the device, so display refresh rate, touch sampling and browser latency all add to it. Compare runs on the same device, and use the consistency figure rather than a single lucky tap.
Does AURA Reflex pay AuraCoins?
No. Reaction times are measured on the device and cannot be verified server-side, so reflex sessions never award AuraCoins, XP or prizes. The leaderboards are for bragging rights only.
Is this a medical or cognitive test?
No. It is a training and entertainment tool. It does not diagnose attention, neurological or any other condition, and it should not be used to make health decisions.
