Are you guys not super sketched out by that website? Self-hosted (and unavailable on f-droid) download (why not just use NewPipe at this point?), vague About Us page, duplicated and almost certainly fake "positive reviews" left by different outlets, etc.
Personally, i just install termux and yt-dlp. Admittedly, i am on a rooted device, but i think some additional tooling is available to give termux access to the shared user storage area.
I got sketched out when I took a closer look at it. I forgot NewPipe existed to be quite frank, it makes much more sense for me to use it instead of the linked app.
