Countdown Timer - Digital
Type in the time and click 'Start' or press 'Enter'.
The maximum number of seconds is 59, the maximum number of minutes is 59 and the maximum number of hours is 99. The online countdown timer feels the digits without colons as minutes.
You may also choose a popup box as a mute alarm instead of an audio option.
The 'repeat' works when the countdown time is five seconds or longer.
