20 seconds · same pattern for everyone today
Tap the green circles. Only those.
Shapes flash one at a time. Tap (or press space) when you see a green circle. Leave every other shape alone, even the ones that look close. Today’s pattern is the same for everyone and changes at midnight.
Twenty seconds is a taste. Five minutes is a baseline.
We make Attention Age, an iPhone attention test. Its five-minute check combines Signal Watch (this game’s big brother), Interference and Tracking, and gives you a 0–100 Attention Index with five category scores, each explained in plain language.
- The app has its own free Daily Signal: one 20-second challenge a day, the same pattern for everyone, with no rankings or fake competitors.
- A weekly re-test uses the same tasks so you can compare fairly. Changes under 5 points are called “about the same”.
- No account, no ads, no third-party analytics. Pro is optional.
What it’s measuring
This is a go/no-go task: respond to one thing, hold back from everything else. Two separate skills show up in your grid. Yellow squares are lapses, a signal you didn’t catch, usually because your attention drifted. Red squares are slips, a decoy you tapped because the “go” habit got ahead of you. Most people lean one way. Knowing which helps more than a single score.
How to read your result
- Catching every signal with no slips on the first try is uncommon. Most first attempts miss one or two or slip once.
- Lots of slips, few misses: you’re fast but trigger-happy. Slow down by a hair.
- Lots of misses, few slips: you’re cautious or drifting. Keep your eyes on the centre.
- Reaction time under about 400 ms is quick for a tap on a phone; it depends heavily on your device and whether you use a mouse or a finger.
A 20-second game is a fun snapshot, not a medical or psychological test. Sleep, caffeine, the device and plain luck all move the result. Everyone gets the same sequence on the same date (by your device’s calendar). Your first result each day is kept in this browser only.
Want a longer test? Try the Schulte table or the Stroop test.
Questions people ask
What is the Daily Signal?
A 20-second focus game. Shapes appear one at a time and you tap only the green circles. Everyone who plays on the same date gets the same sequence, so you can compare grids with friends.
When does it reset?
At midnight on your device. The countdown under your result shows how long until the next pattern.
Can I play more than once?
Your first attempt each day is your Daily Signal result. After that you can play unlimited practice rounds with random patterns.
Does it measure ADHD or attention problems?
No. It is a short game, not a diagnostic test. If you are worried about attention, talk to a doctor.
