Not much, really. Manga Rock is a platform for accessing various manga, while Your Lie in April is a specific manga/anime series. They aren't directly related.
Well, Manga Rock is just a place where you might find Your Lie in April along with many other manga. But Your Lie in April has its own story and popularity independent of the platform.
The connection is pretty loose. Manga Rock is a source for manga, and Your Lie in April is one of the titles that could be available on it. But that's about it. Your Lie in April stands on its own as a great story.
