Stopwatch Apps

There are quite a few of them on the Internet.

They are handy if you believe in the whole Ultradiam rhythm thing where it claims it takes up to 90 minutes for us to lose focus, whereupon we are supposed to take a break.

If you are doing labor-intensive work, you should time yourself for a comfortable amount of time (I suggest 20 minutes) and take a break right after.
