About the Pomodoro timer
Updated June 2026 · 100% client-side — your data never leaves your browser.
Work in focused intervals with the Pomodoro technique: a concentrated work session (traditionally 25 minutes) followed by a short break, with a longer break after every four rounds. Bytewrench's timer cycles between focus and break phases automatically, counts your completed sessions, and lets you customize each duration to match how you work.
Breaking work into timed blocks helps you start tasks, sustain attention and avoid burnout by building rest into the rhythm. The countdown is timestamp-based so it stays accurate across tab switches, and it runs entirely in your browser with an optional chime when each interval ends.
