About this 10-second timer
A one-click 10-second countdown, most often used for quick-fire party game rounds, a photo self-timer, or short stretch holds. It runs in your browser and rings when it reaches zero.
Ten seconds: shorter than it feels
Ten seconds is the length of a classic quick-fire game round, a hand-wash rinse, and the countdown before a group photo. It's short enough that people almost always misjudge it by counting too fast — a visible timer keeps a game or drill honest.
