If you’re on a Mac, take a look at Pomodoro One which has just gone free.

I’m writing to you from my iPad so I can’t get it and try the thing out for you but it comes reasonably recommended and I think you’ll like the Pomodoro technique. It’s just where you work for, say, 25 minutes and then have a break for, say 5 minutes, before you start all over again.

Pomodoro One reportedly looks just like a good stopwatch – and in some stylish way suits the new OS X Yosemite – so that tells you bugger-all aren’t bad things.
