People don’t realize that most platforms (especially YouTube) serve audio and video in separate streams for high resolutions. This app actually does it right. It downloads both and merges them locally. That’s not “low quality,” it’s just how modern streaming works. Tools that pretend to do otherwise are either using AI upscaling or the exact same merging technique behind the scenes. Great job by the dev for doing it transparently! And most importantly, this is good fit as an "all in one" downloader.
