Focus and break timer
Ready.
How the timer works
The focus and break durations are converted to milliseconds. The running timer records an end timestamp and derives remaining time from the clock rather than subtracting one second per visual update.
Worked example
With the default 25-minute focus interval, selecting Start Focus begins at 25:00 and counts downward. If the focus duration is temporarily set to 1 minute for testing, the display begins at 01:00, Pause holds the remaining time, Resume continues the countdown, and Reset restores the configured focus duration.
Limitations
Background tab throttling, device sleep, browser suspension, and notification settings can delay visual updates or prevent the page from acting like a dedicated alarm. Keep the page available if the end signal matters.
Privacy
The timer runs locally in the browser and does not require an account.
Common questions
Can I change 25 and 5 minutes?
Yes. The defaults are editable before starting a new interval.
Does switching modes reset the current interval?
Yes. Starting Focus or Break begins a new interval using the current duration input.
