How it works

Twenty-four teeth and a spring pawl that blocks reverse rotation. Sharp mechanical clicks, one direction only.

The resistance is modelled physics rather than animation: force curves, friction and detent geometry, the same maths that governs the machined metal originals. Here's why that feels satisfying.

Want it in your pocket with real haptics? The free iPhone app has thirteen mechanisms and fires the Taptic Engine on every detent. Get it on the App Store.

Is this ratchet ring free?

Yes. It runs in your browser with no sign-up, no adverts and nothing collected.

Does it vibrate?

On Android Chrome it uses your phone's vibration motor. iPhone Safari blocks the web vibration API, so on iPhone you get sound and motion here — the free iPhone app adds full Taptic Engine haptics.

Do I need to download anything?

No. It plays instantly in the browser on phone, tablet or desktop.
