Crono 2.3

Crono is a program with which you can install a comfortable stopwatch on your computer, which also has a countdown utility.

You can use either of the two utilities independently, that is, with the stopwatch you can measure the time it takes to do something with the computer and with the timer you can program a warning so that you do not forget what you have in the oven while you work. But you can also configure actions of the computer next to the chronometer or timer, such as turning off the computer when the timer time reaches zero or programming the launch of a specific application.

A program that I'm sure you'll find many more applications.
