Based on the Pomodoro Technique, this app gives users the option to begin a 25 minute work session. Depending on the amount of "pomodori" you have cycled through, you are eligible for either a 5 or 15 minute break, indicated by the two soothing-colored buttons on the app.
Pomidor also does a great job of staying out of your way. As soon as you have selected your work (or break) time, it automatically minimizes into the dock, while remaining informative. After the time is up, Pomidor provides a sound alarm (which may be silenced) and a notification. If you want it:
sudo add-apt-repository ppa:dkotrada/pomidor
sudo apt-get update
sudo apt-get install pomidor
