## What it is
PhyTouch is a tiny (2.24 kB gzipped) JavaScript library for smooth touch-driven motion on the web, such as scrolling, rotation, pull to refresh, and page transitions. It maps touch input to any object property with configurable physics-like easing and callbacks, letting developers drive DOM transforms or other animations.

## Use cases
- implement smooth touch scrolling on mobile web pages
- add pull-to-refresh to a mobile web app
- build full-page swipe transitions
- create touch-driven carousels and rotation effects
- animate DOM transforms based on touch gestures
- integrate touch motion with Three.js scenes

## When to choose
- you need lightweight touch motion/scrolling without a large framework
- you want fine control over touch-to-property mapping, easing, and callbacks
- you are building mobile web experiences like pull-to-refresh or full-page scroll
- you want a tiny library that works alongside other tools like Three.js or Omi

## When to avoid
- you need a full-featured scroll/animation framework with momentum, snap, and broad browser support out of the box
- your project targets desktop-only mouse interactions rather than touch
- you need actively developed software with frequent updates and modern tooling
- you are working in a framework ecosystem with native touch handling (e.g., React Native)
