Customize YouTube to work exactly the way you want it to.
I'm using this all the time myself. There is no login to YouTube required and it supports adding subscriptions and doing everything important you can do on YouTube.
Ive been using it for years now and holy shit. Even if it doesnt blocked ads and even youtubers own ads, the app itself is FAR superior than anything what this vanilla youtube app is supposed to be.
I love this app and would use it even if it didn't block ads. The user experience is just so much better than the regular YouTube TV app. I've sent a few donations to the developer to thank them for their work.
