2 minute timer

Two minutes is the length dentists recommend for brushing, and it feels longer than most people expect. A countdown you can see settles the argument.

FreeFullscreen, no ads

The short answer

Two minutes, twice a day, is how long the American Dental Association recommends brushing your teeth. That is about thirty seconds for each quarter of the mouth. Press Start as the brush goes in, and the frame turns amber for the last 24 seconds, which is the cue to move to the last quarter.

How to use it

Three steps to a timer on the wall

  1. Step 1: Choose a time

    Pick a preset or set your own. The timer remembers what you used last on this device.

  2. Step 2: Press start

    Start the timer, then press F or the fullscreen button to fill the screen.

  3. Step 3: Run the room

    Space pauses, the up arrow adds a minute, R resets. Fullscreen shows the timer alone, with no ads and no navigation.

Running it well

Four things worth knowing

  • Thirty seconds a quarter

    Split the mouth into four: top left, top right, bottom left, bottom right. Two minutes gives each one thirty seconds, which stops the front teeth getting all the attention.

  • Let children watch the frame

    The frame around the digits empties as time passes, so a child who cannot read a clock can still see how long is left.

  • The two-minute rule for tasks

    From David Allen's Getting Things Done: if a task takes less than two minutes, do it now rather than writing it down. A two-minute countdown keeps the rule honest.

  • Use a soft sound in a quiet house

    The default chime is gentle. Switch to the loud bell only if the timer is in another room from the sink.

In the room

Built to be read from the back row

A timer that only works on the person running it is not doing the job. The digits scale to the screen, the colour changes before the end, and fullscreen shows nothing else at all.

A productivity rule from David Allen's book Getting Things Done: if something takes less than two minutes, do it straight away instead of adding it to a list.
