Six instruments · one bench
Time, measured precisely.
A countdown timer, stopwatch, Pomodoro timer, alarm clock, interval timer and world clock — each built like a real instrument, with a tick-marked dial and a lit readout. Every second is computed from a real timestamp, not counted by hand, so nothing drifts. Nothing you set here ever leaves this tab. The countdown also comes ready-set on its own preset timer pages — five minutes, twenty minutes, an hour, a boiled egg.
All tools
Countdown Timer
Set it, start it, get an alarm when it hits zero.
Stopwatch
Start, stop, lap — with a clean split table.
Pomodoro Timer
Focus blocks and breaks, on an honest cycle.
Alarm Clock
Set a time on the dial, it rings when you get there.
Interval Timer
Work, rest, repeat — HIIT rounds on a dial.
World Clock
Every timezone you track, ticking at once.
Preset Timers
Five minutes, twenty minutes, an hour — already set, one tap.
Countdown Timer
← All toolsDial in hours, minutes and seconds and clocklab counts down to zero, sweeping the bezel ring around the display as it goes. When time runs out, it rings an alarm built from oscillator tones — no audio file, no download — until you tap Stop.
Screen kept awake while this runs
Ends with an audible alarm — keep this tab's sound unmuted. A running countdown keeps counting in a background tab and picks itself back up if you reload.
Stopwatch
← All toolsA running chronograph hand sweeps the bezel once a minute while the readout counts up in hundredths of a second. Tap Lap while it's running to record a split — clocklab keeps every lap in a table with the gap from the previous one, and highlights your fastest and slowest.

Pomodoro Timer
← All toolsclocklab runs the classic Pomodoro cycle — a focus block, a short break, repeat, then a longer break after a set number of sessions — and moves between them automatically with a soft two-note chime, so you never have to reset a timer mid-flow. The dots above the dial track exactly where you are in the current cycle.
Screen kept awake while this runs
Chimes softly between focus and break — nothing to dismiss. The cycle keeps running in a background tab and resumes where the clock says it should if you reload.
Alarm Clock
← All toolsPick a time and clocklab arms an alarm for it — a small red marker appears on the bezel showing exactly where on the clock face it will ring, while the hour and minute hands keep tracking the real current time. When the clock reaches that mark, it rings until you dismiss it.
Set a time and tap Set Alarm — this tab must stay open for the alarm to ring.
Interval Timer
← All toolsSet a work length, a rest length and a number of rounds, and clocklab alternates them automatically with a chime at every switch — a 5-second get-ready countdown gives you time to get into position before round one. The dots above the dial track exactly which round you're on.
Screen kept awake while this runs
Starts with a 5-second get-ready countdown, then alternates work and rest. Keeps running in a background tab and picks itself back up if you reload.
World Clock
← All toolsA row of cards, each ticking the real current time in a timezone you choose — with the date, the UTC offset, and a small day/night strip showing whereabouts in its day that city currently sits. Add or remove cities freely; your selection is remembered for next time.
