Time estimation test
Try stopping an invisible timer at 10, 30, and 60 seconds. Your result shows the time you actually waited and how many seconds early or late you stopped on each attempt.
How to play
Press Start to begin the 10-second interval. Press Stop when you think that time has passed. Start the next interval when ready. No running clock is shown. Keep this tab visible and avoid using another clock.
Your numbers describe this game on this device, not a clinical ability. This is not an ADHD test. There are no norms or comparisons with other people.
Ready when you are.
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.
