NewPipe [0] is great for this. I watch youtube videos very occasionally, so I'm not going to shell out $10 for this.

It does break sometimes, though, as Youtube changes their website on purpose to thwart NewPipe and youtube-dl, that both parse the website (which, incidentally, is a great way to spur innovation for a generic website parser).

Another option is ublock origin on Firefox mobile.

Firefox mobile + uBlock

If you're on android, YouTube Vanced is amazing. It's actually one of the reasons why I can't see myself switching to iOS anytime soon.

I use Cerctube on iOS, no ads. (no jailbreak either)

Wow, that looks amazing. Didn't know you could sideload apps with the .ipa trick. Maybe I'll finally start using my ipad to watch youtube again.

I don't see an app with that exact name, and I see endless close variants.

As the other comment mentionned it's not on the play store and it's very important to get the app from vanced.app since there are tons of phishing websites pretending to be the official vanced website

It's not available on the app store, and installing it used to be a two step process because it needed micro-g and SAI. They've streamlined it now with an installer app called Vanced Manager. Vanced.app

That's because it's a cracked version of official YouTube app and as such can't be publised on the official store. You need to sideload it.

use NewPipe.
