## What it is
A small Android helper library that wraps the circular reveal animation API into a fluent one-liner interface. It supports showing/hiding views with ripple effects and full-screen color/image transitions before launching activities.

## Use cases
- create circular reveal animations on android views
- hide or show a button with a ripple animation
- animate a full-screen color overlay before starting an activity
- trigger a ripple expansion from a specific view or point
- customize animation duration, radius, and interpolators

## When to choose
- you want simple one-line circular reveal animations on Android
- you need Dribbble-style ripple transitions for view show/hide or activity launches
- you prefer a tiny helper class you can copy into your project

## When to avoid
- you need animations beyond circular reveal, like shared element or motion layouts
- you are not building for the Android platform
- you need a library with an explicit license or active maintenance guarantees
