Alarms that ringWhy use these tools
- Accurate. Time is calculated from your device clock, so it doesn't drift when the tab is in the background.
- Remembers where you were. Reload or close the tab and your stopwatch or timer is still running when you come back.
- Built for phones. Big buttons, a full-screen mode and a layout that fits one hand.
- Private. No account and no cookies. Settings stay in your browser.
