Online chime timer FAQ

Hourly chimes, without installing anything

What is an online hourly chime timer?

An online hourly chime timer plays a gentle sound in your browser at the interval you choose, such as on the hour, every 30 minutes, or every 15 minutes. It is useful when you want a lightweight time reminder without installing anything.

Can this browser chime every 15 or 30 minutes?

Yes. Chimebird can chime on the hour, every 30 minutes, every 15 minutes, or on a rolling 15 or 30-minute interval from the moment you start it.

Does the web timer work after I close the tab?

No. Browser audio needs the tab to stay open. The iPhone app is the better option when you want chimes to ring on the lock screen, in the background, or without keeping a browser tab open.

Can the iPhone app chime when the phone is locked?

Yes. The iPhone app schedules local notifications ahead of time, so chimes can ring on the lock screen and keep working without the app staying open.
