I am looking for for an app that registers as a YouTube endpoint, but has no ads and tracking (or backdoors). I had one (forgot the name) which stopped working. Please advice.
Newpipe + Sponsorblock is a really good option.
Removed the trending tab, made my tabs “What’s New” “Subscriptions” “Bookmarks” and “History”. Made a few categories in the Subscriptions tab to sort specific channel types into different feeds. Bunch of minor tweaks to the video player/SponsorBlock settings. Honestly I recommend just taking the time to go through all the settings to configure it exactly how you want.
