I'm aware of FreeTube and PlasmaTube, which IIRC both require an Invidious instance. There was something called SMTube in the past, not sure if it still exists.
Nothing I'm aware of has both desktop and mobile version, but if anything there are more options for mobile YouTube clients; try NewPipe or Clipious.
Edit: SMTube does still exist. It does not require Invidious, but it does use tonvid.com.
oh it is still being updated! great.
