Online Timer
A web timer should do three things well: start instantly, keep perfect time in a background tab, and get your attention when it ends. This one measures elapsed time from the system clock rather than counting ticks, so tab throttling cannot drift it - a 25-minute pomodoro finishes in 25 real minutes. At zero it plays three beeps and flips the tab title to an alarm, so you notice it even from another window.
Type minutes and seconds or hit a preset chip (1, 3, 5, 10, 15, 25, 45, 60), press Start, and glance at the tab title anytime - the remaining time lives there, which is the whole point of a timer you are not watching. Your last duration is remembered for the next session, and a share link carries the exact time you configured, so 'start a 10 minute timer' is one message to a friend or a class.
How to use
- Set minutes and seconds, or tap a preset chip for common durations.
- Press Start - the tab title becomes a live countdown you can watch from any window; Pause and Reset are one keypress away.
- At zero: three beeps sound and the title switches to an alarm. Share button sends the exact timer as a link.
Frequently asked questions
Is the timer accurate in a background tab?
Yes - each refresh recomputes remaining time as end-time minus the system clock, instead of trusting that setInterval fired on schedule. Background tabs throttle timers to roughly once per minute, but wall-clock math is immune: the display might refresh late, the finish moment never moves.
Does it make a sound at zero?
Three 880 Hz beeps via the Web Audio API - no audio files, no autoplay restrictions to fight because sound only plays after you clicked Start. The tab title also flips to an alarm message, covering muted devices and silent mode.
Can I use it for pomodoro or workout intervals?
Presets cover the classics - 25 minutes for pomodoro focus blocks, 45 for long sessions, 5 for short breaks, 3 and 1 for planks and rest intervals between sets. The remembered-last-duration feature means repeat intervals are two clicks: preset, Start.
Does it work offline or without an account?
No account, no install - it is a plain page that runs entirely in your browser, and once loaded it keeps working with no network at all. Bookmark it and your duration settings follow you on this device.
