## What it is
An Android UI library providing a TickerView component that animates scrolling text changes, like an odometer, with customizable character lists and animation styles. It draws directly onto the canvas for high performance and handles string resizing animations.

## Use cases
- animate stock price changes in an Android app
- display odometer-style scrolling numbers
- animate text transitions between values like 9999 to 10000
- show scrolling counters or tickers in a mobile UI
- add smooth text change animations to Android text views

## When to choose
- you need performant, smooth scrolling text animations on Android
- you want odometer-like number transitions with customizable character animation
- you need a lightweight custom View that avoids layout overhead

## When to avoid
- you need a cross-platform or non-Android solution
- you need extensive text styling beyond the limited customization subset
- your project is not on the JVM/Android toolchain
