3 Hour Pomodoro Timer with Brown Noise — 25/5 Study With Me for Deep Focus & ADHD

Three hours is an exam-revision session or a deep work morning. Six cycles. By the fourth the timer stops being a rule and starts being a rhythm you are just following. The screen is split. The left half counts your 25 minutes of focus; the right half holds at 5:00, waiting. When the focus block ends they swap — the break side lights up, the focus side dims and resets. You never have to work out which phase you are in, and you never have to look at a number to know how much is left: the ring around the icon empties as the time does. A soft bell marks every change. Nothing else in 3 hours asks for your attention. WHAT'S UNDER IT Brown noise, and only brown noise. No music, no talking, no lyrics, nothing with a structure your brain can start following. Brown noise falls off more steeply toward the high end than white or pink, which is why it reads as a low rumble rather than a hiss — closer to heavy rain or distant surf than to static. It masks the sounds that break concentration without becoming a sound you concentrate on. The noise here is synthesised, low-passed at 1.6 kHz to take the fatigue out of the top end, and mixed quiet on purpose. If you can hear it clearly you have it too loud. HOW TO USE THIS 1. Pick one task before you press play. Not a list — one. 2. Work while the left side is lit. When the bell goes, stop mid-sentence if you have to. 3. Actually take the break. Stand up. The 5 minutes are load-bearing. 4. Do not skip ahead to see how much is left. The ring is there so you do not have to.
