Keepvid.com seems nice in that the home page says "Batch download YouTube
playlists with one click" and "Convert YouTube to MP3" on the front web
page (and it handles 10,000 other sites, it says).
They reference on the bottom of the home page this CBS article:
https://www.cnet.com/how-to/how-to-download-videos-from-youtube-vimeo-and-more/
The legality for personal use is ok is what the CNET article says, as
commercial sale and hence commercial distribution of the downloaded
material is what's illegal in the USA (they said).
That CNET how-to-download article listed the best as
1. KeepVid
2. NetVideoHunter (Firefox only).
3. Free YouTube Downloaderhttp://

4. MacTubes for Mac

What is perhaps not all that surprising is that the Android newsgroup came
up with a far better answer, as did the Windows newsgroup, both of which
easily met the simple criteria of (no browser, no money, no login, no ads,
no nothing) and all passed the 3 testcases easily:
Since those two options don't exist for iOS, and even though KeepVid used a
browser and doesn't support MP3, I tested it out on the three test URLs:
http://keepvid.com/?url=https%3A%2F%2Fyoutu.be%2FAI5wEcWAmkg
http://keepvid.com/?url=https%3A%2F%2Fyoutu.be%2FVuNIsY6JdUw
http://keepvid.com/?url=https%3A%2F%2Fyoutu.be%2FCBrsWPCp_rs
They all worked fine.
At first it seemed as if a "login" or "registration" was required, since
I pasted the test URL into
keepvid.com https://youtu.be/CBrsWPCp_rs and
only then does it say
"Content can't be played. It seems you are not logged into your account"
but it still allows you to click the button to download it anyway (so
that's just a recommendation, I guess).
So keepvid passed the no-registration test, and then for each file, it
downloaded them just fine (with a minor inconvenience regarding handling
KeepVid's "videoplayback" naming conventions).
So of the test goals we set a week ago for Android & Windows:
(no browser, no money, no login, no ads, no nothing)
KeepVid only failed one (which isn't too bad).
It's not an iOS solution by any means in the same way as the Android &
Windows solutions were, but it certainly works on iOS since it's a
browser-based solution.
