Start here. Take the Focus Check before your first focus session. It takes about 5 minutes on Quick and sets the baseline your progress is measured against.
How long can you hold your focus?
Three short tasks borrowed from attention research measure how fast you react, how long you stay on task, how easily you get pulled off course, and how steady you are. You get a score out of 100, a breakdown and a history of every session you run on this device.
Use a quiet spot. On a computer you'll use the keyboard; on a phone, large tap buttons appear. Results from a phone and a computer aren't comparable, so stick to one device.
Before you start
- Sit somewhere quiet and silence your phone and notifications.
- Use the same device every time. A laptop with a keyboard gives the steadiest numbers.
- Set aside the full time. Each task starts only when you click its Start button, so you can pause between tasks.
- Every task opens with a picture of what to do. The second task also has a 20-second practice round.
The three tasks
Watch the counter
What to do: a box sits empty. When numbers start counting inside it, hit Space (or tap) as fast as you can. Don't press before it starts.
Circles, not diamonds
What to do: a new shape in a new colour grows in about once a second. If it's a circle, hit Space. If it's a diamond, do nothing. About 1 in 10 shapes is a diamond.
Follow the middle arrow
What to do: five arrows appear. Press ← or → for the way the middle arrow points. Ignore the others.

Your attention today
50 is typical. Scores are percentiles against provisional reference values.
What this means
How to raise your score
Scores usually rise a little over your first 3–4 sessions as the tasks become familiar. Look for steady gains after that, tested at the same time of day.

You can also right-click (or long-press) the card to save it.
History
How your score was calculated
Full measurement table
Each raw measure is turned into a z-score against a reference value, clipped to ±3. Within a dimension the main measure counts 60% and the others share 40%. A dimension score is the percentile of that z-score (100 × Φ(z)). The overall score combines the four dimensions, adjusted for the fact they're correlated (r ≈ 0.3).
Reference values are provisional placeholders from published studies and online norms, not a validated norm for your age or device. Browsers add 10–50 ms of delay that varies by device, so compare yourself against your own past results on the same device.
