45 Seconds Timer
Set this 45 Seconds timer and let the countdown start. Use it to control the time limit of any activity and be notified when that limit has been reached. When the countdown stops, you will receive a message on your browser warning you, and an alarm sound will ring.
When setting the timer, you can select between different sounds and pick the one you like the most or that is more likely to get your attention. On the same menu, you can also name the timer and choose if you want the alarm sound to only go off once or if it should keep ringing until you turn it off manually.
