Thanks for sharing! Though personally I've been only using https://vidmateapp.pro/ to download stuff for the most part. It's the best way to go if you want to be able to get the videos not only from YouTube, but from Instagram, TikTok, etc, as well. I feel like it's so much easier for me to keep them organized like this, cause otherwise I forget where I saw that funny video, or that other one that I wanted to use for a project, or that presentation video of a new nail salon that I wanted to go to. It's just what works best for me, but this app you shared looks like it has some awesome features as well.
