Marinara Timer is a free web-based Pomodoro tool that requires no sign-up or installation. You open the website, pick a timer, and get to work. It is one of the most straightforward ways to start practicing the Pomodoro Technique. The site offers three timer modes. The first is the standard Pomodoro cycle of 25 minutes of focus followed by short and long breaks. The second is a custom timer where you set your own session and break lengths. The third is a kitchen timer style countdown for quick use. A nice feature of Marinara Timer is the ability to share a link to your timer. This lets teams or study groups work with the same countdown running. Everyone can stay synchronized without needing extra apps. The interface is minimal, with no extra distractions. A large clock shows the time remaining, and simple sound alerts notify you when sessions and breaks are complete. Marinara Timer works on any device with a browser, from laptops to phones. It is completely free, with no ads or hidden costs. If you want a no-frills Pomodoro timer that you can launch in seconds, Marinara Timer is one of the easiest choices.
