NewPipe – ad-free, open-source Android YouTube client
This is the best youtube client, bar none.  It keeps local history and "subscriptions" without requiring you to log in to google.  I use it on an Amazon Fire Tablet.  There seems to be no iOS equivalent, which is one of the things preventing me from upgrading to an iPad.Has anybody used it recently on AndroidTV / FireTV?  I've tried it several times in the past, and its always been wonky there.  I use SmartYouTubeTV (https://smartyoutubetv.github.io/) on AndroidTV right now, and the logged out experience is terrible.
