Downloading apps on an LG Smart TV can enhance your viewing experience. Generally, you can access the LG Content Store from the home screen and browse or search for the app you wish to download. Once you find the app, select it, and then click "Install" to start the download process. Have you recently got the TV, or are you looking for a particular type of app? Let me know if there's a specific app you're interested in, and I can guide you further!
