The interface is very basic. It has one large window where you can find all the options: pasting a link, downloading a video, and choosing the file's quality and format. Once you've located the video you want to download, choose the format in which you want to save it. You can save just the audio or the entire video. Finally, choose the file's quality to make sure the resulting file is either of great quality or else compressed to take up less space on your hard drive.
All the files that you download will go to the same folder, so you can manage them at the same time without having to search for them first. To download a video to your computer, all you have to do is look it up on YouTube; copy the URL, which will be automatically copied to the application; and download it with just one click.
