Is there a good Android app that saves videos from YouTube for offline viewing?

XA Downloader is a straightforward video-saving utility designed to download content from a wide array of websites, with YouTube being a primary use case. The app operates through a built-in browser, allowing users to navigate to a video, where a download button typically appears. It supports multiple resolutions and formats, giving users control over file size and quality. For someone looking to save a tutorial, lecture, or music video for a commute without reliable internet, this functionality is particularly practical. Reviews indicate the download speeds are consistently good and the saved videos play back without issues. A key feature is the background download capability, letting users switch to other tasks while a file saves. However, the experience can be influenced by the source website's own restrictions, and some users note that the interface includes advertisements. For basic, no-fuss video downloading from YouTube and similar sites, XA Downloader provides a reliable, user-friendly solution, though it operates in a legal gray area dependent on copyright and terms of service of the source platforms.
