Bounded time is easier to focus in
Committing to a fixed stretch and then truly resting removes the fatigue of open-ended work. That is what interval and pomodoro timers are for.
Focus & Productivity
Timers, notes, routines and ambient sound to shape your working rhythm.
Focus comes from environment and rhythm more than willpower. A timer that bounds the work, a note that empties your head, a sound that covers distraction — small devices that genuinely change output.

Externalising tasks frees working memory. These tools persist to browser storage, so a refresh does not lose your notes.

Frequently asked questions
Does the timer stay accurate in a background tab?
Yes. Timers compute from absolute timestamps, so they resynchronise correctly even if the browser pauses animation while hidden.
Where are my notes stored?
In your browser's local storage only. They do not sync across devices and are removed if you clear site data.
