Just a Second

How well do you know 1 second

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Can you tap to exactly 1 second? Sounds easy. It's not. Free to play — see how precise your internal clock really is. How well do you know a second? Tap to start. Tap again when you think the time is up. That's it. Simple to learn — impossible to perfect. Three modes to test your internal clock: - Challenge — a new random target every round, from 1 to 10 seconds - 1 Second — the classic. How close can you get to exactly 1.000s? - 5 Seconds — harder than it sounds. Your score is measured in milliseconds. Your ego is measured in how many times you retry. No ads. No subscriptions. Just timing.
