Dual Wallpaper is a free Android app developed by Yanndroid that allows you to customize your device even further by having two separate sets of wallpapers for light and dark mode. With this app, your wallpaper will automatically change to the one you've selected when your device's theme changes. Additionally, you can switch wallpapers based on the time.

The app offers a variety of options for each wallpaper, including choosing an image, a plain color, or a gradient for both the light and dark mode wallpapers. You can also set different wallpapers for the lockscreen and homescreen. This level of customization allows you to create a unique and personalized look for your device.

One of the standout features of Dual Wallpaper is that it is completely free and does not contain any ads. This means you can enjoy all the customization options without any interruptions or distractions.
