Tomato Clock от Samuel Jun

Use Tomato Clock to break down your work sessions into 25 minute 'Tomato' intervals separated by short breaks. Take a longer break after completing four Tomato intervals.

Features:

* Customizable timer lengths
* Browser notifications
* Stat tracking

You can customize the length of the Tomatoes and breaks in the extension page. Tomato Clock uses the default browser notification system, accompanied by a sound, to let you know when the timer is up. Tomato Clock also features stats for tracking how many Tomatoes you complete.
