Pomodoro Timer for iPhone is an app that looks like a cooking timer, but might be just the thing to get you to focus on work.
The default color for the app is red which indicates it's time to work. When you complete one Pomodoro a tomato will fill one of the circular placeholders along the bottom. As you complete more Pomodoros, more tomatoes appear to track your productivity.
