I know I'm probably in the minority here but.... I'm a desk jockey.
I don't use Lemmy on a handheld. I didn't use Reddit that way either. The web interface works well enough for me, or rather whatever lemmy.ca uses is good when set to vaporwave-light. Try the different themes, some are better than others.
The pagination though... it's a little short for my taste but I prefer it over doomscrolling.
