Marinara Timer is a free web-based Pomodoro tool. Unlike mobile apps, it works directly in your browser. There is no signup needed, which makes it fast and accessible. Here is how it works. You open the site, choose a timer mode, and start working. The default is the classic Pomodoro cycle of 25 minutes of work followed by a 5-minute break. You can also set custom timers or use a kitchen-style countdown. One feature that stands out is its shareable links. When you start a session, you can copy the link and share it with others. This is useful for study groups or remote teams who want to stay in sync. Everyone can see the same timer running. Because Marinara Timer is web-based, it runs on any device with a browser. You do not need to install anything. This makes it convenient for people who want a simple tool without extra features. The app does not overwhelm you with reports or task management. Instead, it focuses only on timing sessions. This makes it lightweight and distraction-free. Marinara Timer is often used by students during study sessions or by workers who need quick structure during the day. It works well for people who do not want to manage an account or download an app. If you want a free and simple Pomodoro timer that works instantly in your browser, Marinara Timer is a solid choice.
