## What it is
A custom RecyclerView LayoutManager for Android that lays out a grid of photos while preserving each image's aspect ratio. It is a drop-in Java library from 500px distributed via a custom Maven repository.

## Use cases
- display a photo grid that respects image aspect ratios
- build an image gallery feed in an Android app
- replace GridLayoutManager with variable-height rows
- show a masonry-style photo wall in RecyclerView
- layout mixed-size images in a grid without cropping

## When to choose
- you need a justified photo grid like 500px or Flickr on Android
- you want a drop-in LayoutManager with minimal setup
- your images have varying aspect ratios and must not be cropped

## When to avoid
- you need a uniform fixed-size grid (use GridLayoutManager)
- your project is not Android/RecyclerView based
- you need actively developed features or Jetpack Compose support
