4 Hour Pomodoro Timer 15/5 for Deep Work and Study with Soft Fan White Noise

Staying productive during long study sessions requires a rhythm that prevents burnout. This four-hour timer uses a structured fifteen-minute work and five-minute break pattern, often referred to as a modified Pomodoro technique. Every four cycles, you get a longer fifteen-minute break to step away, stretch, and grab a glass of water. A gentle warning chime sounds sixty seconds before a phase ends, followed by a soft bell at the transition itself. This keeps you aware of your time without throwing you out of your flow state. The visual design is kept entirely minimal to eliminate digital distraction. A static, dark, warm-toned gradient stays on screen, showing only the current timer progress. It is dark enough to keep open on a second monitor or on your desk at night without casting a harsh glare across your workspace. Beneath the timer, a steady, low-level cooling fan sound plays continuously. This gentle hum masks sudden background noises like distant traffic, footsteps in the hallway, or a roommate moving around, helping your mind settle into deep focus. This setup is ideal for high-intensity tasks that benefit from short, sharp bursts of attention. Whether you are tackling a pile of reading for an upcoming exam, writing code, organizing a chaotic inbox, or drafting a creative project, the fifteen-minute intervals make daunting tasks feel manageable. For the best experience, set your volume so the fan sound sits comfortably in the background rather than dominating your room. If you are using headphones, a lower volume is recommended. The audio runs continuously across the work and break cycles, maintaining a consistent acoustic environment so your brain stays in the zone even when your body is resting.
