## What it is
A small JavaScript plugin that adds a custom 'shake' event to mobile web browsers using the device accelerometer via the devicemotion API. It lets web apps trigger actions (like shake-to-undo) when the user physically shakes their phone or tablet.

## Use cases
- detect shake gesture in mobile web app
- implement shake to undo on iphone/ipad web app
- trigger action when user shakes phone in browser
- listen to device accelerometer shake events in javascript
- add shake event listener to mobile website

## When to choose
- you need shake gesture detection in a mobile web browser without native code
- you want a tiny dependency-free library using the W3C devicemotion API
- you need broad legacy mobile browser support including older iOS and Android

## When to avoid
- your app runs only on desktop browsers without devicemotion support
- you need native app shake detection rather than web
- you need a maintained solution - the project has not been updated since 2018 and modern mobile browsers restrict devicemotion to HTTPS with user permission
