A focused reaction time test with single-round and five-round modes. Reaction Time Test is a lightweight browser-based test for measuring how quickly you respond to a visual signal. It includes two test modes: • Single Round — get a quick reaction time result with one attempt. • Five Rounds — complete five attempts and view your average reaction time. Wait for the signal to appear, respond as quickly as you can, and see your result in milliseconds. Recent results and personal bests can be kept locally in the browser, making it easy to repeat the test and compare your performance over time. Reaction Time Test runs directly in Chrome with a simple interface and no unnecessary setup.
