Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

In the AppStore, search Vinegar. Works for me. 👍

Not many options out there for native apps, but you can use an Invidious or Piped proxy and pin the website as an "app".

There definitely is a way with jailbreaking, as I’m sure there are tweaks for youtube on the repos. But that requires an exploit.

With no jailbreak - you can sideload this: https://github.com/qnblackcat/uYouPlus

There are a handful of options if you’re looking for a tweaked version of the YouTube app (no jailbreak needed) with enhanced options (blocking ads, skipping sponsored segments, allowing downloads, enabling PiP)

I personally use YouTube Reborn Plus https://github.com/arichorn/YouTubeRebornPlus

As for loading the IPA onto my iPhone I use Sideloadly. https://sideloadly.io

I know a lot of others use AltStore. https://altstore.io

Keep in mind, if you have a paid Apple Dev account like myself you only have to load the app on your device once a year. But, if you have a free account you’ll need to do this weekly. That being said, that is why so many users prefer AltStore, it automates the process to ensure you don’t hit that weekly threshold.

I can’t say how, but somehow I turned my iPhone XR into a black box that has no YouTube ads on Chrome.

Brave browser. It has an ad blocker built in.

Firefox Focus appears to let me play youtube without ads, but I’m unclear if it’s because I also have the Vinegar extension (which shouldn’t matter, since the extension itself says it only works in Safari.)
