Timers
15 Minute Timer
A fifteen-minute countdown with an alarm at zero — the length of a short Pomodoro break, a quarter-hour meeting, or one focused block of tidying up.

Alarm and notifications
A short tone plays automatically when the timer ends, synthesised in your browser — nothing is downloaded or streamed.
Works even if you switch tabs
This timer tracks the clock time it should finish at, not a count of ticks, so switching tabs or locking your device never makes it run late. The tab title above shows the time left even while you’re looking at something else.
A fifteen-minute HIIT block
Fifteen minutes is a common length for a single high-intensity interval training session, built around short bursts of hard effort separated by brief rest — a typical structure might be thirty seconds of work followed by thirty seconds of rest, repeated enough times to fill the block. The value of a countdown here isn't just marking the finish; it's that when you're breathing hard mid-interval, counting rounds in your head reliably goes wrong, and a timer visible on the floor beside you removes that entirely. Run the full fifteen minutes as one block, or set shorter custom intervals within it if your app or coach specifies a different work-to-rest ratio than a simple even split.
A fifteen-minute tidying sprint
Fifteen minutes is a commonly used length for a focused decluttering or tidying sprint, sometimes called a speed-clean, and it earns that specific length by being short enough that starting doesn't feel like signing up for a whole afternoon of cleaning — which is usually the actual obstacle to starting a tidying session at all, not the tidying itself. Set the timer, pick one room or one surface, and move continuously rather than stopping to deeply reorganize any single area; the time pressure of a visible countdown is part of what keeps a fifteen-minute sprint from turning into an hour spent sorting one drawer. When the alarm rings, stopping is the point — repeated short sprints beat one long session you keep avoiding starting.
Keeping a check-in meeting to a quarter hour
Fifteen minutes is a useful slot for a meeting that needs more room than a five-minute stand-up but doesn't warrant blocking out a full half hour — a one-on-one, a quick status sync, or a single decision that needs actual discussion. Starting the call with a visible countdown running changes the tone before anyone's said a word: it signals the meeting is genuinely meant to be short, and it gives whoever's leading it a neutral, non-awkward way to wrap up when the alarm sounds rather than having to personally cut someone off. A meeting that consistently overruns its fifteen minutes is a real signal worth acting on, not just a reason to reach for a longer preset next time.
Fifteen minutes as a study or reading block
Fifteen minutes also works as a single focused reading or study block for material that's dense enough to need real attention but doesn't call for a longer Pomodoro-style session — a journal article, a dense email you've been putting off answering properly, or one topic within a larger study session. Treat the alarm as the signal to genuinely pause and assess rather than push straight through into the next unrelated task, since the whole value of a short fixed block is the checkpoint at the end of it, not just the timing.
Past fifteen minutes
Fifteen minutes sits between the ten-minute and twenty-minute presets, and if your particular block or sprint consistently needs a bit more or less, the custom hours/minutes/seconds fields beside the one-tap presets hold any exact length with the same alarm and pause behaviour as the preset itself.
Questions
- Is fifteen minutes long enough for a real workout block?
- Fifteen minutes is a common length for a single high-intensity interval training block, and it works because HIIT is built around short, hard efforts with brief rest rather than sustained duration — a fifteen-minute block of 30-seconds-on, 30-seconds-off intervals gets through a genuinely demanding session without needing an hour set aside. Running it against a visible countdown rather than counting rounds in your head is what keeps the work-to-rest ratio honest when you're breathing hard and losing track. If your specific interval structure needs a longer total block, the custom hours/minutes/seconds entry extends past fifteen minutes with no change in how the alarm behaves.
- Why do quick decluttering sessions work better with a timer?
- Fifteen minutes is a commonly cited length for a focused tidying sprint — sometimes called a speed-clean — specifically because it's short enough that starting doesn't feel like committing to a whole afternoon of cleaning, which is often the real barrier to starting at all. Setting a visible countdown turns a vague 'let me tidy up a bit' into a bounded task with a clear end, and the time pressure itself tends to keep you moving from item to item instead of getting pulled into reorganizing a single drawer for ten minutes. When the alarm sounds, stopping is genuinely allowed — the point of the fifteen-minute sprint is consistent small progress, not finishing the whole room in one sitting.
- How long should a quick check-in meeting actually run?
- Fifteen minutes is a common slot for a focused check-in that needs more room than a stand-up but doesn't warrant a full half-hour block — a quick one-on-one, a status update between two people, or a decision that needs discussing but not a full agenda. Setting a visible countdown at the start of the call does real work here: it signals to everyone that the meeting is meant to be short, which changes how people pace what they say, and it gives whoever's running it a neutral way to wrap up without having to be the one who says 'we need to stop.'
