Reaction time test
See how long you take to respond to a visual cue. Wait for the sky to turn copper, then tap. Five completed rounds give your average and fastest response in milliseconds.
How to play
Press Start. Wait for the word Tap and the copper sky, then tap the target or press Space or Enter. Early taps do not count. You will get a fresh wait before trying that round again.

Frequently asked questions
Is this an ADHD test?
The games and planning tools are not ADHD tests. They cannot diagnose ADHD or change an ASRS screening outcome. Only the separately labeled adult screener provides an official screening result, which is still not a diagnosis.
Where does my information go?
Games keep personal bests only in local storage on this browser. Task checklist text stays in this tab. Blank PDF downloads contain no personal data. Tool analytics send event names only, never your numbers or task text.
What do game numbers mean?
They describe this attempt on this device. Timing includes your device and input method. Interruptions, practice, and the way you play can change the numbers. There are no population comparisons or clinical interpretations.
