Airy can pause and resume downloads and allows you to download complete YouTube channels and playlists with the possibility to download each item in the best available quality.
When you log in to your YTB account you can save age-restricted and protected YTB videos to your computer too. The application is capable of handling Full HD and 8K Ultra HD videos without hiccups.
And it is not just plain download, Airy actually allows choosing a resolution for saved videos, downloading YouTube subtitles, and saving MP3 files instead of the whole video, for those cases when you only need a soundtrack. The app will also fetch album art & titles from the files. If you want to download many videos at a time, just add the whole bunch of YouTube links to Airy and click "Download".
