Pomodoro - Must for Chrome
More About Pomodoro - Must
This extension utilizes already great pomodoro tool tomato.es and adds annoying browser notifications to constantly remind you that you MUST be in pomodoro mode.
Lightweight: If you close tomato.es tab extension becomes completely idle and is removed from the memory. Just re-open it again and extension will start its work!
Safe: No 3rd party calls, your data stays secure in the tab <-> extension communication channel.
