Ad Guard works like an extension for Safari, so once you've downloaded and installed it, open up the Settings app and click on Safari, followed by Content Blockers. Install an ad blocker called Ad Guard, which has a free feature specifically for blocking YouTube ads. Unfortunately, you can't disable ads in the YouTube app itself, but there is a way to block them by watching YouTube in a browser. Are you tired of being bombarded with ads while watching YouTube on your iPhone? Well, you're in luck because I have two solutions for you!
