As a supplementary service offered au gratis with your Crunchyroll subscription, their this app service is pretty great. You get a no-nonsense UI with basic bookmarking and favoriting to keep up with your favorite series, and an interface that works well.
As a proprietary service, it feels anemic. While there are notable works made available, like A-Jin, Seven Deadly Sins, and Arakawa Under The Bridge, the library is overall pretty small — especially when compared to the substantial collection on Crunchyroll’s primary anime and j-drama service.
It also doesn’t have a particularly good storefront as a result. Since the library is so small, there’s no need for discoverability or genre classification — which, in and of itself, is a problem worth addressing should they ever expand its collection. However, new series don’t pop up on here often enough to inspire confidence.
It’s great as a free offering to Crunchyroll, which is already a pretty hefty service, and you won’t run into low-quality art or amateurish translations like in free services, but it’s still got a ways to go in a market desperately in need of strong competition, and it starts with the library.
