Questions

Is it free?

Yes. No account, no ads and nothing to install.

Does it work offline?

Once the page has loaded, yes: the clock and the bell run in your browser.

Does it ring with the screen locked?

It depends on the browser. The page asks for the screen to stay on while the clock runs; if your browser doesn’t allow it, keep it on yourself.

Does it save my settings?

Only in your browser, so your rounds are there next time. Nothing is sent anywhere.
