Sensory Hourglass Timer
A calming visual timer: fine sand trickles through an hourglass, or colored drops sink through liquid.

Free Calming Sensory Hourglass Timer for Classroom Focus & Quiet Time
For many children, “five more minutes” is hard to picture — and a ticking number can feel like pressure. A sensory visual timer shows time instead of telling it: fine sand trickles from the top of the hourglass to the bottom, or colored drops sink slowly through a liquid motion bubbler, so students can see at a glance how much time is left. The steady, gentle motion is soothing to watch, which makes it a natural fit for a Calm Down Corner, independent reading, brain breaks and transitions. Students with ADHD or autism, and young learners who can’t yet read a clock, often find it easier to wait, focus and self-regulate when the time is something they can watch. You can hide the numbers completely, and the timer ends with a soft singing-bowl chime instead of an alarm.
Use the sensory timer in 3 steps
Choose the time. Tap a preset — 1 Min (Brain Break), 2 Min (Calm Down), 5 Min (Quiet Reading) or 10 Min (Focus) — or type any time up to 99:59 on the number pad and press Set.
Pick a calming look. Choose Classic Hourglass or Liquid Motion Bubbles, decide whether to show the countdown numbers, and turn the gentle end chime on or off.
Start and watch. Press Start. Pause whenever you need to, and use Flip / Reset to turn the hourglass over for another round. Classroom Presentation Mode fills the screen with a soft pastel background and no ads.
Ways to use it in your classroom
A timer for the calm-down corner
Set the 2 Min (Calm Down) preset on a classroom tablet or laptop, turn off Show countdown numbers and let a student watch the sand fall. At the end, a soft singing-bowl tone plays and the screen says, “Time’s up — take a slow, deep breath.”
Settle into independent reading
Choose 10 Min (Focus) or 5 Min (Quiet Reading), switch to Liquid Motion Bubbles and open Classroom Presentation Mode. The slow drops give the room a calm focal point, and students can glance up to see how much reading time is left without reading a clock.
Gentle transition warnings
Students who find changes hard often do better when they can see a transition coming. Start a short hourglass a few minutes before you switch activities, so the class watches the time run out instead of hearing a sudden “Clean up now.”
Fair turns at a center
For a shared iPad station or a favorite toy in pre-K and kindergarten, type a turn length on the number pad, press Set, then Start. When the sand runs out, press Flip / Reset Hourglass to turn it over for the next child.
Frequently Asked Questions
How does a sensory hourglass timer help students?
It turns time into something students can see. Watching the sand or drops move shows exactly how much time is left without reading a clock, which reduces anxiety about transitions, supports self-regulation in a calm-down corner and helps students with ADHD, autism or other sensory needs stay focused.
Can I hide the digital countdown numbers?
Yes. Turn off Show countdown numbers and only the hourglass or bubbler is shown, so students watch the calm motion instead of counting down the seconds. The sand and drops still move in exact step with the time left.
Is this timer free for classroom use?
Yes. It’s 100% free with no sign-up and no downloads, and it runs in any modern browser on Chromebooks, iPads, laptops and interactive whiteboards. Your time and display choices are saved in this browser.
What’s the difference between the two visual themes?
Classic Hourglass shows fine sand trickling into a pile in the bottom bulb. Liquid Motion Bubbles shows colored drops sinking slowly through liquid, like a liquid motion toy. Both follow the same countdown exactly, so either one is an accurate picture of the time left. Your choice is saved in this browser.
Can I set a time that isn’t one of the presets?
Yes. Type digits on the number pad like a microwave — 3 0 0 is 3:00 — and press Set. Any time up to 99:59 works. If the timer is running or paused, press Flip / Reset Hourglass (or Refill / Reset for the bubbles) first, because the time settings lock during a run.
Will the end sound startle sensitive students?
The timer ends with a soft singing-bowl tone, not an alarm or a buzzer. Press Preview to hear it before you use it with a student. For a completely silent finish, turn off Gentle chime at the end — the timer then simply shows a calm “take a slow, deep breath” message when time is up.
