The timer will tell you when your 4 hours has run out. It will keep counting minutes and seconds upwards instead.
Sound notification (alarm) is optional. You can keep the timer running in the background if you for example open a new tab. If you have sound notification the timer will tell you when time is up (just remember to turn up the volume on your computer or smartphone).
