You can get NewPipe from F-Droid if you're on Android. It does PeerTube and even Bandcamp streaming. It also allows you to use YouTube ad-free - and there's a version with built-in SponsorBlock for skipping those in-video ads/promos.
For Android have a look at NewPipe. You can add PeerTube instances and watch there.
But AFAIK it was removed from the Play Store because it lets you watch YouTube Videos without Ads.
