## What it is
A small Android library providing 31 easing animation interpolators (cubic, elastic, expo, etc.) usable with ValueAnimator and ObjectAnimator. It takes a single linear ratio parameter (0 to 1) instead of the standard 4-param ease signature.

## Use cases
- add easing curves to Android view animations
- use elastic or bounce interpolators with ValueAnimator
- animate view translation with cubic easing
- apply ease-in-out curves to ObjectAnimator
- get more animation timing options than the built-in Android interpolators

## When to avoid
- you are not developing for Android
- you need actively maintained code with recent updates or a declared license file

## Facets
- artifact type: library
- maturity: maintenance
- function: animation
- domain: mobile-development, android-tools
