# F1 Reaction Time Test

An unofficial Formula 1-style reaction game: wait for five start lights to go out, then click, tap or press Space across five valid starts and compare your median, best and consistency.

## Description

The browser game recreates a five-light race start. A false start is tracked; after five valid starts it reports median, best launch and consistency. It is free, has desktop and mobile controls, and no mandatory signup. The author states it is independent and not affiliated with Formula 1.
