A 90 minutes timer you can see
This page opens with 90 minutes already set. Press Start and the colored disc shrinks clockwise until it is empty, so you can tell how much time is left from across the room. A soft two-note chime plays at the end, with a quiet heads-up one minute before.
What to use a 90 minutes timer for
People use a 90 minutes timer for a deep work block, a long exam, a movie-length study session or a long bake. Ninety minutes is a common deep work block: long enough for hard, focused work, followed by a real break.
Change the time in one tap
Need a little more or less? Tap one of the nearby lengths, type your own (90 means 90 minutes, 1:30 means one minute thirty, 45s means 45 seconds), or add a minute while the timer runs. Full screen puts the disc on a tablet, TV or second monitor.
Frequently asked questions
Why do people work in 90 minute blocks?
Ninety minutes is a popular length for one deep, uninterrupted session followed by a proper break. Try it for hard thinking work and see if it suits you.
Is this 90 minutes timer free?
Yes. No signup, no ads in the timer and nothing to install. Open the page and press Start.
Can I pause or add time?
Yes. Pause and Reset work at any time, and the add-a-minute button extends a running timer.
Will the timer keep running if I switch tabs or lock my phone?
The countdown is calculated from the clock, not by counting ticks, so the time left is always correct when you come back. Some phones pause the sound while the screen is locked, so keep this page open and the screen on if you need the chime to ring on time. The Keep screen on option helps where your browser supports it.
Does this timer save or upload anything?
No. The timer runs entirely in your browser. Nothing is uploaded, and there is no account. Only your last choices, such as sound on or off and the color, are remembered on your own device.
