FitnessPrompt is a Chrome extension designed to remind users to take breaks and engage in health-promoting activities while working. It aims to address the health concerns that arise from prolonged periods of inactivity and stress. The extension displays full-page notifications prompting users to perform activities like drinking water, taking a walk, and resting their eyes at regular intervals.

One of the key features of FitnessPrompt is the full-screen activity break notifications with countdown timers. These notifications pause when the user is idle, ensuring that breaks are timed effectively. Additionally, users can customize settings such as break intervals, duration, title, description, and themes. Notifications are intelligently disabled during non-working hours to respect users' personal time and weekends.
