Frequently asked questions

Do the timers work offline?

After the page has loaded, the timers keep running without internet.

Why does my timer seem slow in a background tab?

Browsers limit background tabs to save power. The time stays correct because it is based on the clock, but beeps can arrive a moment late.

Are the timers free?

Yes. No sign up and no limits.
