Reaction time, explained properly
Everything we figured out building the tests (the real numbers, what they mean, and how to get faster), with the studies cited so you can check us.
What Is Reaction Time? A Plain-English Definition
What is reaction time, in plain English: the gap between a signal and your response, measured in milliseconds. The definition, the types, real examples and how it is measured.

Why your reaction time feels slow, and why most 'slow' scores are device lag, tiredness or the wrong benchmark rather than your brain. How to tell, and what actually fixes it.
