## What it is
An extendable Java framework of multitouch gesture detectors for Android, modeled after Android's built-in ScaleGestureDetector. It provides detectors for rotation, movement, and two-finger shove gestures that plug into the standard OnTouchListener pattern.

## Use cases
- detect two-finger rotation gestures in an Android app
- move objects around the screen with one or more fingers
- detect vertical two-finger shove gestures
- pinch-to-zoom and rotate images or maps
- build custom multitouch gesture detectors on Android

## When to choose
- you need rotate, move, or shove gesture detection on Android beyond the built-in ScaleGestureDetector
- you want a clean, object-oriented, extendable gesture detector framework
- you want drop-in classes following the Android gesture detector pattern

## When to avoid
- you only need pinch-to-zoom scaling, which Android's built-in ScaleGestureDetector already provides
- you need gesture recognition for complex shapes or machine-learned gestures
- you are not developing for Android
