Is there a mobile app where you can read manga as well as watch anime from? I guess the question is as detailed as it can get:
I'm looking for a legal mobile app where you can read manga as well as watch anime from.

Looking forward for your answers.
You can read manga and watch anime with Crunchyroll on Android. The anime app can be used by free members ad-supported, or by paid members ad-free. The manga app however is exclusively for paid members

CR Manga App , 
CR Anime/Drama App

Similarly for iOS:

CR Manga App ,
CR Anime/Drama App 

Windows Phone:

(No Manga App) , CR Anime/Drama App 

Most apps have anime and manga separate, presumably for development purposes (It's arguably easier to have them separate). I don't think there are any apps (for Android at least) that combine the two in one app.

As far as news apps for anime go, Crunchyroll have one. But I came across Daily Anime News, which compiles several different news sites in one place. (Both Android)
