As someone who watches a fairly wide variety of tv shows, “next episode” has been the most useful app on my phone for me. It helps so much for knowing what to subscribe to and when. Only sub when my favorite shows come out and catch up on the rest then. I’ve also discovered some new shows through their upcoming and trending lists (which is more of just a bonus and not why I got the app to begin with). It’s probably the only app I would give my full recommendation for anyway.
