About this tool

Measures your display's refresh rate by counting requestAnimationFrame callbacks over one second. Common values: 60 Hz (standard laptop / phone), 90-120 Hz (mid-range phones + tablets), 144 Hz (gaming monitor), 240 Hz+ (esports). A moving dot underneath gives you a visual check — smooth motion means the browser is actually drawing at the measured rate.
