Since people talk a lot about Invidious lately, I would like to share this great desktop app for those who don’t know it yet. It uses Invidious and lets you watch YouTube without ads. It even has SponsorBlock (you might need to enable it in settings though). You can add videos to favourites and see the history - all stored locally. It’s Free Software.
Freetube is great, its my main way to watch YouTube on Desktop. For iOS i just found yattee. If configured the right way its basically newpipe for iOS
