Managing a block of time is different from managing a task list: it means putting a hard edge on how long something runs. Countdown Clock counts down to any date or deadline and turns into a shareable link, and Breathing Pacer paces a box-breathing or 4-7-8 rhythm to structure a focus interval. White Noise Generator holds a steady white, pink or brown noise bed underneath either one so a work block doesn't get broken by outside noise.
The clock, the breathing rhythm and the noise bed all run locally in the browser tab — nothing is logged to an account, and a shared countdown link carries the date in the URL itself rather than a server record. No sign-up, no timer limit, no ads breaking a focus block.
