What app is so useful you can’t believe it’s free?

@SW-User Use NewPipe. It completely improved my experience of watching YouTube for the better. Completely free. That being said, you cannot use your account with it, and subscriptions on it is basically just a list of favorite channels, and doesn't actually make you count as a subscriber for that channel. You basically cannot do anything requiring an account with it (except for age-restricted videos, NewPipe bypasses the account requirement for that), which means commenting or liking videos. Honestly, commenting on YouTube is pointless and generally seen by no one, so not really a big loss. You lose interactivity in general, but no ads, and the ability to better control your viewing experience bring it way up!

@X6900ES I never heard of it, thank you so much
