How long can you hold your attention?
Not a quiz. A real measure: two classic tasks from attention research, about four minutes, honest numbers at the end. Nothing to sign up for. Nothing leaves your browser.
Four minutes, two tasks, one honest snapshot.
Attention research does not measure focus by asking how focused you feel. It watches what your responses do over time. This test does the same.
React
A ring lights up at unpredictable moments. Tap as fast as you can. Eight lights, under a minute. This is your raw reaction baseline, the same idea behind the psychomotor vigilance task used in sleep and attention research.
Sustain
Digits appear about once per second. Tap for every digit except 3. It is easy for ten seconds. The real test is whether your mind is still there at ninety. Adapted from the Sustained Attention to Response Task.
See yourself
Your unbroken focus time, reaction speed, consistency, and impulse control, with a score whose formula is shown in full. Saved only on your device, so you can retest after a week of practice and watch it move.
Your attention, measured.
How this score is computed
Attention is trainable.
Your score is a snapshot of a skill, not a verdict on a self. A bad night of sleep moves it. So do stress and screens. So does practice. Train daily for a week, come back, and watch the number move. Your results stay on this device, so the comparison will be waiting.
