4 hours
The 4-hour timer counts down exactly to zero and immediately shows the equivalent of 4 hours in minutes and seconds. The interface is simple: the Start, Pause, and Reset buttons respond instantly. Full-screen mode is activated with a single tap, and the end notification sound can be easily adjusted by volume or turned off.
