Reaction Time Tests — Measure Your Reflexes Online

Reaction time is the gap between a stimulus appearing and your physical response to it, measured in milliseconds. It is a core performance metric in competitive gaming, driving safety, and sport. These free reaction tests measure multiple dimensions of your reflexes — from pure visual response speed to sustained target-tracking accuracy under pressure.

The average person's visual reaction time is 200–250ms. Athletes and competitive gamers who train consistently typically average 150–200ms. Elite players at the top of their performance range measure 120–150ms. Your reaction speed is influenced by sleep quality, caffeine intake, ambient lighting, monitor refresh rate, and the amount of dedicated reaction training you do — all controllable variables you can optimize.

The Reaction Time Test gives you a pure baseline in milliseconds. The Aim Trainer measures your accuracy under reactive pressure. Whack-a-Mole tests sustained reactive clicking across a full timed session. The Key Reaction Test translates reaction measurement to keyboard input. The APM Test measures your total input throughput across keyboard and mouse combined.

Start with the Reaction Time Test to establish your baseline. Then use the Aim Trainer for 10–15 minutes daily — most players see measurable improvement within two to four weeks of consistent practice.
