How to use 3 minutes and 30 seconds timer
The timer will tell you when your 3 min and 30 sec has run out. It will keep counting minutes and seconds upward 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.
