About this tool
Trigger your device's vibration motor with a few preset patterns, or build a custom one — a simple way to check the vibration motor still works, or to preview a pattern you're designing for a web app's notification feedback.
Frequently asked questions
- Why doesn't anything happen on my laptop or desktop?
- The Vibration API only works on devices with an actual vibration motor — Android phones/tablets in Chrome or Firefox support it, but desktops, iPhones, and iPads don't expose it at all (iOS Safari has never implemented the Vibration API), so nothing will happen there regardless of the browser.
- How does the custom pattern work?
- Enter a comma-separated list of millisecond durations that alternate vibrate, pause, vibrate, pause... — so "200, 100, 200" vibrates for 200ms, pauses 100ms, then vibrates 200ms again.
- Can I stop a long pattern early?
- Yes — the Stop button calls the same API with an empty pattern, which immediately cancels whatever is currently vibrating.
