Reaction Time New Tab

Measure your reaction time every time you open a tab. Works offline, keeps a personal best and a daily streak.

Every new tab becomes a five-second reaction test. Wait for the screen to turn green, then click or press any key. Your time appears immediately, along with your personal best and how many days in a row you have played. WHAT IT DOES - Measures reaction time on the key press, not the release, so results are comparable with other reaction tests - Keeps your personal best and a daily streak - Tells you how your time compares with the typical 273 ms - Nothing else. Your new tab stays fast and quiet. PRIVACY - No permissions requested at all - Nothing is sent anywhere. Your results stay in your own browser. - No account, no sign-in, no tracking Works with no internet connection.
