There's such a vibrant modding scene, you're missing out on a lot. It's almost like playing a Bethesda RPG without mods. So many quality of life mods and content expansions, chief among them Stardew Valley Expanded, which feels like a professionally made DLC that seamlessly integrates itself into the game, to the point that you often aren't sure whether what you're seeing is from the original game or made by these modders.

Looking around, it might be a bit tricky to install on Android, but people have done it.
