Accurate

Time is measured from the clock, not counted in ticks, so it does not drift or slow down in a background tab.

Survives a reload

Running timers, your saved timers and your history are kept on this device. Close the tab and pick up where you left off.

Loud or silent

Nineteen alarm sounds, a volume control, optional notifications, and a flashing screen when sound is not an option.
