Be focused and mindful to do productive work

A free Pomodoro timer and a website blocker for chrome so you can be focused and productive while working or studying.


Highly reccomended! The interface is user friendly and pleasing to look at, and the game-like features (death count, hard mode, times distracted) are a great way to keep users engaged.
