About
Simple Timer is a free countdown timer that runs entirely in your browser. No login, no tracking, no uploads. Everything stays on your device.
How to use
Use +30s, +1m, +5m, 25m, or 1h to set your duration, then press Start. While running, the bar shrinks and shifts color from calm to urgent.
Use Space to start or pause quickly. Reset clears to 00:00 and restores the default interval.
FAQ
