    Why ninety minutes

    Ninety minutes is a common length for a deep work session, a long exam or a sports match half plus break. Many people plan their hardest task in one ninety minute block, then take a real break.

    Questions and answers

    How do I start the 90 minute timer?

    The timer is already set to 90 minutes. Press Start, or press the Space bar on a keyboard. Press it again to pause, and press Reset to bring back the full 90 minutes.

    Will it make a sound when time is up?

    Yes. A soft chime plays when the time is up, and phones that support it also vibrate. Use the Sound button to turn the chime off for quiet rooms.

    Does it keep time if I switch tabs or lock my screen?

    The timer counts from the clock, so it stays accurate in a background tab. While it runs, urTimer asks the screen to stay awake so you can keep watching it.

    How many seconds are in 90 minutes?

    90 minutes is 5,400 seconds.

    Can I change the length or the look?

    Pick another preset, drag the Classic dial, or choose Custom for any time up to 12 hours. Under Style you can switch to an hourglass, a candle, a progress bar and more, and pick your own colors.
