What we build
We provide clean test patterns, browser timing measurements, and plain-language guidance for pixels, OLED wear, color, and motion.
What we do not claim
A browser cannot objectively measure Delta E, luminance, physical contrast, input lag, or pixel response time without external equipment. When a result is visual or approximate, we say so.
How it works
The tests run locally in your browser. Core tools require no account, software download, or result upload.
