## What is Just a Second?

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.
