Does the timer keep running if I switch tabs?

Yes. The timer is based on the real clock, so switching tabs or returning after a browser pause shows the correct remaining time. Keep the tab open for the finish sound and notification.

Will it make a sound when it finishes?

Yes. Choose one of five alert sounds before you start. When the timer finishes, the selected sound repeats until you press Stop alert or Reset; the Repeat setting can limit it to one or three plays instead.

Can I use the timer offline?

Yes, after the page has been cached on your device. Install Clockfresh or revisit once while online, then the timer shell can load without a connection.

Online Timer — free, no ads, offline-ready

About this timer

The Clockfresh online timer is a free, ad-free browser countdown timer with presets, fullscreen mode, five alert sounds and offline support after caching. Use it for cooking, studying, workouts, focus sessions and meetings: pick a preset or set your own time, press start, and Clockfresh counts down with big, easy-to-read digits. A running timer is saved in your browser, so it survives a reload and follows you to other Clockfresh pages as a small floating widget. There are no ads and no sign-up.
