Timer with Alerts

A countdown only helps if you hear it.

Kitchen timers, study blocks, and stretch reminders all share one problem: you look away for thirty seconds and miss the end. A timer with alerts stacks a visible ring, an audible tone, and optional system notifications so the finish line reaches you even when your attention drifts.

The whole thing runs in your browser. No account, no upload, no server holding your session label or volume preference. Settings land in local storage on your device and stay there until you clear them.

When a ring beats glancing at a clock

Wall clocks and phone lock screens work until you step into another room or mute your phone.

Here the SVG ring shrinks as seconds pass, shifting from calm indigo toward amber and red in the final stretch. Pair it with one of four synthesized tones (beep, chime, bell, alarm) and, if you grant permission, a desktop or mobile notification. On supported phones, vibration adds a tactile nudge. Test the sound before a real session. A silent laptop on mute teaches a hard lesson fast.

Four signals, one finish line

The tab has to stay open (mostly)

Honest limitation upfront.

Close the tab and the countdown stops. Background tabs also get throttled by Chrome, Safari, and Firefox to save battery, so a timer left running behind twenty other windows might drift by a few seconds over a long session. Browser notifications help when you switch apps, but they are not a substitute for a hardware alarm in a kitchen with a sleeping baby or for medical dosing schedules. Keep the tab visible for pasta water. Rely on notifications when you are coding in another window.

Study blocks, simmer timers, and the five-minute trap

Students label a session "Chapter 4" and run twenty-five minutes before a break. The preset row includes a Pomodoro slot, though a dedicated Pomodoro timer tracks work and rest cycles with session stats if you want structure beyond a single countdown.

Cooks set ten minutes for sauce reduction or two hours for slow roast checks. Open-ended tasks belong on the stopwatch instead: you start timing now and stop when the task ends, no fixed endpoint.

HIIT rounds and repeated work-rest pairs fit the interval timer better than resetting this page between sets. For a deadline tied to a calendar date, the countdown timer counts down to a specific moment rather than a duration you type in.

Freelancers who bill by the hour often pair alerts with the work time tracker so a finished session becomes a logged block. When you need to know how long two timestamps span after the fact, the duration calculator answers in plain hours and minutes.

Keyboard shortcuts stay out of the way until you want them: Space to start or pause, Ctrl+S to apply settings, Ctrl+R to reset. Nothing here replaces professional scheduling software. It gives you a labeled countdown with a sound you chose, running locally, for the stretches of life where "I'll check the clock" never quite works.
