30 Second Digital Timer

A 30-second digital timer puts a big, unmissable LED countdown on the shortest intervals — the ones where a single glance has to tell you everything. Bright enough to read across a gym floor or a classroom, with no hands to interpret.

About the 30 Second Digital Timer

Thirty seconds goes fast, so the display does the work — oversized digits mean you never lose a rep counting in your head.

Frequently Asked Questions

Does the 30 second digital timer keep accurate time in the background?

Yes. It counts down against the real clock rather than ticking in the tab, so your 30 second digital timer stays accurate even if you switch tabs or lock your screen — and the alarm still sounds at zero.

Can I change the duration, or switch away from the digital clockface?

This page opens preset to 30 seconds on the Digital clockface, but you can set any duration and switch to a different clockface at any time using the controls below the timer.
