You’re painting yourself into a corner by avoiding degoogled Android operating systems. I guess my suggestion for you would probably have to be to install yt-dlp on your server, and then use an SSH app when you need to download a video. Maybe someone more familiar with Apple can offer a better suggestion.

I always recommend Seal just because I can never remember the name of this app. Has anyone made use of both and has an opinion on which is better?

If you installed with pip, simply re-run the same command that was used to install the program

Simply running pip install yt-dlp doesn’t update though, right? You need to add an upgrade flag, so either:

• pip install yt-dlp --upgrade
• pip install yt-dlp -U

EDIT: Maybe I should actually read this documentation that I am commenting about. Their steps to initially install it with PIP mention to use the -U flag anyway. That flag is meant for updating, but it won’t make the package install wrong if used during initial installation of the package or anything, so no reason not to.

As others have already said, yt-dlp is absolutely the gold standard. It even works in Termux. As for a dedicated Android app, there are apps like Seal which are effectively just wrappers for yt-dlp. Then the open source YouTube clients like Tubular, which are primarily for browsing/watching videos, have a download button on every video.
