Focus on the target
We tell you which symbol to tap (e.g. green circle).
How strong is your sustained attention?
Symbols flash one after another — tap only when you see the target. This measures real-world alertness: hits, false alarms, and reaction speed under distraction.
How it works
Ignore distractors
Wrong taps lower your alertness score.
