Proton Movies The lightweight YouTube experience for Android.

Do you like watching videos on YouTube but looking for a simple app to do that?
NewPipe has been created with the purpose of getting the original YouTube experience on your smartphone without annoying ads and questionable permissions.

You can use NewPipe on devices or custom ROMs that do not have Google apps installed.
