Startup Idea: Pomodoro Technique Application Development

Startup idea to develop an app that implements the Pomodoro Technique. The app would allow workers to keep track of tasks and integrate timed breaks, facilitating efficient work processes. Once reaching four tasks, a longer break is granted, improving productivity and mental health.

I would like to see a good app implementing the Pomodoro Technique. It basically allows workers to take a small break every 25 min. During the 25 min workers work on a task and when the timer goes off they place a check mark if they completed the task. Once reaching 4 check marks they get a longer break. No good software has implemented this and I would really like to use it with my team.
