It's actually not a new app, but it just received support for Seoul today: https://citymapper.com/seoul/
There is a web interface, plus apps for Android and Apple. It seems to be surprisingly well localized, including realtime information for 따릉이 as well as the maglev! It's quite sluggish on my old phone, but I imagine it's alright on newer models. The way they've included the subway map isn't at all useful. However, this app focuses on telling the user how to get to their destination, rather than focusing on map details. It's definitely different from using the Jihachul app/Seoul Bus/Naver, but it looks promising.
