Doro is a Chrome extension developed by turtlemooncake that serves as a simple Pomodoro timer. With Doro, users can easily choose between a 25-minute work session or a 5-minute break. The extension keeps track of the number of sessions and breaks completed, providing users with a clear overview of their productivity.

One of the key features of Doro is the "Restart Count" button, which allows users to reset all counters back to zero. This is useful for starting a fresh Pomodoro cycle or tracking progress over a specific period of time.

While Doro is a straightforward and user-friendly extension, it does have a minor limitation. Users can inadvertently run multiple timers simultaneously by clicking on the same timer after closing the extension popup. Additionally, the timers do not stack, so selecting the 25-minute timer twice does not create a 50-minute timer.

Overall, Doro is a handy tool for individuals looking to implement the Pomodoro technique into their work routine. Its simplicity and ease of use make it a convenient choice for Chrome users.
