How to play

A duration appears on screen — 7.34 s, for example. The moment you press, a stopwatch starts, but it stays invisible. Release when you think you're there. The app then shows your real time and your gap.

The smaller the gap, the better. Under 0.10 s, the screen reads DEAD ON.

Why it vibrates while you hold

That's deliberate, and it's the whole point of the game. With nothing to disturb you, everyone would simply count in their head and get the same result. The vibrations and clicks are irregular on purpose, on two streams that never line up, precisely so that no pulse can be used as a reference.

You can turn them off via the gear icon on the home screen. Just be aware the game becomes considerably easier.

Frequent questions

• I don't feel any vibration.Check that Vibration is on in the app's settings. If the row is greyed out with "Not available on this device", your model has no haptic engine — the game still works with sound.
• The daily challenge isn't changing.It renews at midnight, on your phone's local time. Only one attempt per day is allowed: that's what makes scores comparable between players.
• I lost my streak.A streak breaks as soon as a day is skipped. There is no way to restore it — that's what gives it value.
• My round was cancelled.If the app goes to the background during a hold — incoming call, notification, system gesture — the round is discarded rather than recording a distorted time.
• Party mode isn't showing scores.That's intended. They stay hidden until the end, otherwise each player would calibrate on the previous one's result. Everything is revealed in the final standings.
• Is my data collected?No, none at all. See the privacy policy.
