How the check works
Part 1 — habit quiz
The quiz is seven questions. Each answer is worth 0, 1, 2, or 3 points. Zero is the calmer end of that question. Three is the more overloaded end. The quiz total is the sum, so it runs from 0 to 21.
The questions are specific on purpose. They ask how many hours you spend on TikTok, Reels, or Shorts; whether you can watch something longer than five minutes without skipping; how many browser tabs are open; when you last read a book rather than a feed; what you do with ten free minutes; how you would rate your own attention; and how two hours without Wi-Fi would feel. They are prompts for honesty, not a validated psychological scale.
Part 2 — reaction task
After the quiz, a target (a brain icon) appears in a random spot inside the play area. You tap it as soon as you see it. That happens for five rounds. The site averages your five times in milliseconds.
The average becomes a second score, separate from the quiz: under 300 ms is 0 points, 300–499 ms is 3, 500–699 ms is 6, and 700 ms or slower is 9. Faster tapping adds fewer points. The task is there so the result is not only a story you tell about yourself. It is still a rough home measurement. Take it on the same kind of device if you want to compare two days.
Putting the two scores together
The diagnosis screen adds the quiz points and the reaction points. That total is mapped to a tier: 0–7 is tier 0, 8–15 is tier 1, 16–22 is tier 2, and 23 or above is tier 3. The highest possible total is 30 (21 from the quiz and 9 from the reaction task).
You can retake the check. The new quiz and reaction scores replace the ones stored in this browser. Nothing is sent to an account, because there is no account.
Part 3 — arcade, only if you want it
The arcade is nine short games: a focus clicker, memory match, a sequence repeat, speed arithmetic, paced breathing with a tap, word unscramble, a colour-versus-word tap, odd-one-out, and tapping numbers in order. Each game keeps the best score on this device.
A results view that compares your diagnosis tier with a later tier opens after three different games. If those games add up to at least 48 points, the displayed tier moves one step toward tier 0. If you have played at least six games and the points add up to at least 160, it moves two steps. It will not move past tier 0, and a weak arcade session does not make the tier worse. That rule is a scoring choice inside this product. It is not a claim that three games repaired anyone’s attention.
