Why OneTapTimer?
Instant, not installed
Every tool runs in your browser the moment the page loads. No downloads, no accounts, no waiting.
Private by design
Timers run entirely on your device. We never see what you count down to, and nothing is uploaded.
Accurate by default
Countdowns are anchored to your system clock, so pausing tabs or busy pages won’t drift your timer.
