A 45 minute timer you can see
Forty-five minutes is about one lesson: a class period, a tutoring session or one deep block of work.
This is a visual timer. The time is a blue disk that shrinks as the minutes pass: more disk, more time. You can read it in one glance from across a room, with no numbers to work out. The last minute turns amber, and the end is one soft chime.
What 45 minutes are good for
- A class period or a tutoring session.
- One section of a practice exam paper.
- A deep work block on a single project.
- A meeting that has to end on time.
One tip
In a classroom, put the timer on the big screen in full-screen mode and switch the numbers off. Children read the shape, and nobody needs to ask how long is left.
Other timer lengths
1 min · 2 min · 3 min · 5 min · 10 min · 15 min · 20 min · 25 min · 30 min · 45 min · 60 min
Need a different length? Type any number of minutes from 1 to 180 in the Custom box, or open the main visual timer, which remembers the length you used last. For work and break cycles that run themselves, use the pomodoro timer.
Why a shape works better than numbers
Numbers only help if you can feel what "45 minutes" is like. For many children, and for many people with ADHD, that feeling is unreliable. This is often called time blindness. A disk that shrinks turns time into something you can see, so nobody has to guess. More in our guide to visual timers.
Questions about the 45 minute timer
Is 45 minutes too long for ADHD?
It can be. Name one task, keep the disk in view and plan a real break after. If starting is the problem, begin with a shorter timer and work up.
Can teachers use this on a classroom screen?
Yes. It runs in any browser with no account. Full-screen mode fills the display, and the clock-face option shows the time as a 60-minute dial.
Is this 45 minute timer free?
Yes. It is free, with no signup and no account. It runs in your browser on a phone, tablet, laptop or classroom screen.
Does the 45 minute timer make a loud alarm?
No. It plays one soft chime at the end and the disk turns amber, not red. You can switch the sound off with the bell button.
