Why these timers

• Accurate in the background. Time is calculated from your device clock, so switching tabs does not slow a timer down.
• Alarm and tab title. The remaining time appears in the browser tab, and an alarm sounds when time is up.
• Full screen and screen-on. Show a big timer on a projector, and keep the screen awake while it runs where your browser supports it.
• Private. Timers work entirely in your browser. A few settings, such as your Pomodoro lengths, are saved only on your device.

Timers run in a web page. For anything safety critical, use a dedicated device. Keep the tab open and the device awake for long timers.
