You can run Komga or anything with OPDS support then install and app that supports OPDS on your tablet. Mylar has a built in OPDS server option if you’re extra lazy 😎
I use Komga and “Paperback - A Komga Client” for my phone/ipad which I find to be a bit smoother then other OPDS clients though.
I personally use Tachiyomi or CDisplayEx if its on android. Or if it's on my iPad then I use the paperback app using repos, or for my own collection I LOVE YAC reader. The guy who develops it is super cool and actually listens to requests when they make sense and it's way better than Kavita or Komga IMO if you don't mind using your PC as a server.
