What's a good Android app for quickly downloading videos from random websites to watch offline later?

HD Video Downloader Quick Save is a straightforward tool designed for downloading video content from a wide array of websites for offline viewing. Its primary strength is the integrated browser, which simplifies the process: users navigate to a site, play a video, and the app detects and offers a download link. This is particularly useful for saving instructional content, such as a cooking tutorial from a niche blog or a travel vlog from a personal website, where dedicated apps are not available. The app supports resolutions up to HD and offers format selection for some sources, providing basic control over file size and quality. Batch downloading is another practical feature, allowing a user to queue several videos from a site like a lecture series page before leaving Wi-Fi. However, its effectiveness is entirely dependent on the source website's structure, and some sites with complex video players or anti-download measures will not work. User reviews indicate the download detection can sometimes require a manual refresh of the page. Occasional in-app advertisements are present in the free version, which can interrupt the workflow. For the specific task of grabbing videos from disparate, non-standard websites, it serves its purpose reliably, though results are not guaranteed for every single site.
