About ReactionMetric
ReactionMetric is a focused browser benchmark built around one simple idea: if you are going to measure yourself, you should be able to see exactly what was measured and what uncertainty remains.
The first release focuses on reaction time and visual reflex testing. It does not claim to be a medical diagnostic and it does not hide device/browser uncertainty behind a synthetic “calibrated” number.
What we are building
Fast tests, transparent methodology, local personal history, and eventually a first-party browser benchmark with visible sample sizes and comparable environment cohorts.
