Why it works
It feels simple until the clock disappears.
That is the hook. The target is clear, but on Medium and Hard the counter hides before the stop. You count it out, trust the beat in your head, then find out whether you were early, late, great, or perfectly on target.
1
See it
Each round gives you a target time to hit.
2
Feel it
The timer can hide, so the round becomes a real timing challenge.
3
Beat it
Stop reveals your miss, awards points, and sends you chasing the next run.
Built for quick solo runs and pass-it-around challenges.
Use it like the stopwatch challenge you see in short videos, or play it as a real score chase. Same one-tap mechanic, three kinds of pressure.
Ten-round climb
Ladder
Climb from one second to ten, one round at a time. No death — you play all ten, and the lowest total miss wins.
Your sandbox
Free Play
No score, no pressure. Choose what's hidden, set a target or run a plain stopwatch, and practice however you like.
Not just a stopwatch
The hidden counter turns timing into a game.
The regular Stopwatch app can count up. Stop the Timer gives you a target, hides the clock, scores the stop, and remembers your best runs. A timing game only matters if you trust the result, so each tap is read from the exact instant your finger lands.
- Your tap is timed from the exact touch instant — not a delayed animation frame — so a PERFECT is a real PERFECT.
- Every result shows exactly how early or late you were, down to the hundredth of a second.
- Difficulty changes what you see, never the rules — so every run still comes down to your timing.
