Rain Drop Live Wallpaper is an Android app that simulates raindrops falling on your screen with different backgrounds. It offers customization options with its "Custom Photo" feature that allows you to load your own photos. To use the app, simply go to Home -> Menu -> Wallpapers -> Live Wallpapers.

The app is free to download, but it contains ads in the settings screen. The developer, Wasabi, implemented these ads to support the development of more free live wallpapers. However, if you experience your wallpaper resetting to the default after a reboot, you will need to put the app on your phone instead of your SD card. Overall, Rain Drop Live Wallpaper is a simple and easy-to-use app that adds a nice touch of raindrops falling on your screen.
