Time Blocker is a Chrome add-on developed by timeblockerapp that serves as a timer for working and studying using the time blocking technique. This technique involves working or studying intensively for a set amount of time, followed by a short break. Time Blocker helps users implement this technique effectively by providing customizable timers for different sessions.

The main features of Time Blocker include three different timers for work/study sessions, small breaks, and big breaks. Users can customize the duration of each session to suit their preferences. Additionally, Time Blocker offers the option to play a "ding" sound or open a small popup window when a session ends, ensuring that users stay on track.

To enhance convenience, Time Blocker provides keyboard shortcuts to start any of the three preset timers or stop the currently running session. The add-on also displays a badge on its icon, indicating the remaining minutes for the session. This feature eliminates the need to open the add-on to check the time left.

Overall, Time Blocker is a valuable tool for individuals who want to enhance their productivity and focus while working or studying. By implementing the time blocking technique with the help of this add-on, users can effectively manage their time and achieve their goals more efficiently.
