Adaptive icons are an Android feature (introduced in Android 8.0) where app icons provide separate foreground and background layers, allowing the system or launcher to apply different shapes, animations, and dynamic colors.

An icon mask is the shape applied to app icons by your launcher — circle, squircle, rounded square, teardrop, or others. It controls the uniform silhouette of all icons on your home screen.

A squircle is a mathematical shape between a square and a circle, commonly used as the icon shape on Samsung devices and in icon packs like Ares that provide a consistent, modern icon container.

AMOLED Wallpaper
AMOLED wallpapers are designed with true black (#000000) areas that save battery on OLED screens, since black pixels are physically turned off and consume zero power.

The depth effect is an iOS feature that makes your lock screen wallpaper appear three-dimensional by placing the clock and widgets between the foreground subject and the background of the image.
Read more →Live Wallpaper
A live wallpaper is an animated or interactive wallpaper for Android or iOS that moves, responds to touch, or changes based on time, weather, or other conditions.
