FFF Wallpaper: Parallax 3D is an Android personalization app developed by ilnioramaxtrig. It is a full version program that works on Android 9.0 devices. This app allows you to create a parallax effect on your device by slightly offsetting the position of the wallpaper. It is also capable of obtaining the device's rotation angle data from the Rotation Vector Sensor in real-time.

The app's main feature is the parallax effect, which creates a 3D-like illusion on your device's screen. By slightly offsetting the wallpaper's position, it creates a sense of depth that reacts to the device's movements. The app also allows you to customize your wallpaper by choosing from various designs and colors. With its real-time sensor data, the app ensures that the parallax effect is always accurate, creating a seamless and immersive experience for the user.
