What makes this a free classroom timer teachers actually use.
A free classroom timer for every part of the day.
Timers for Class is a free classroom timer built for teachers, not a stopwatch app that happens to work in a classroom. Open any timer and it's ready in one click — no account, no download, and no ad breaks interrupting a countdown mid-lesson. Every timer runs entirely in the browser, so this digital timer for classroom computers, Chromebooks, and projectors works on whatever device you already use to run a lesson, and it keeps working after the bell without a subscription or a locked "pro" tier. It's a classroom timer online you can trust to just work — today, and every day after.
Exam timers for tests, fun timers for everything else.
Every timer on the site fits one of two moods. Exam timers — the wall clock, hourglass, candle, battery, beaker, and stopwatch — are quiet, precise, and built to run for a full class period without distracting anyone, counting down for up to 12 hours to cover anything from a quick quiz to a full testing block. Fun timers — shapes, balloon, rocket, animal race, flower bloom, volcano, firecracker, traffic light, and pencil — trade precision for personality, topping out around 3 hours with sound effects built in, making each one a genuinely fun classroom timer for brain breaks, transitions, and classroom games.
A giant classroom timer that's readable from the back row.
Every countdown is drawn with oversized numerals and high-contrast shapes designed to be projected, not just glanced at on a phone. One click puts any timer into fullscreen, turning it into a giant classroom timer that fills the whiteboard or projector screen for the whole room to see. While a timer is running, the page also keeps the display awake, so the screen never dims or sleeps in the middle of an exam or a timed activity.
A visual timer for kids of every age.
Not every student reads a countdown number the same way, which is why each timer pairs the numbers with a visual timer for kids: sand draining through an hourglass, a candle burning down, a battery losing its charge, or a balloon slowly deflating before it pops. Younger classrooms can lean on the shapes timer or the animal race, where the passage of time is something to watch rather than read, while older students get the same information from a traditional wall clock or stopwatch face — it's an online timer for kids that works just as well for the adult running the room.
Set a classroom timer for 10 minutes — or twelve hours.
Every timer ships with one-click presets, so setting a classroom timer for 10 minutes takes exactly one click, and switching to 5, 15, 20, 30, 45, or 60 minutes takes one more. Need something longer or more specific? Type in any custom duration, and the exam timers will hold up to 12 hours for full testing blocks. The duration is saved right in the page's URL, so a timer can be bookmarked or shared with a co-teacher already set to the exact length it needs to run.
A classroom timer with music, for brain breaks that actually land.
The shapes timer goes a step further than sound effects: pick a shape, pick a color, and choose from a handful of built-in music tracks to turn a countdown into an actual classroom timer with music. It's built for brain breaks, indoor recess, and any moment where a silent countdown would undersell it — a fun class timer that gets kids watching the clock instead of the classroom door.
