I am an active user of this app. Excellent work there and do keep it going. I see that you are at the beginning stage of app development.
The features I love and use the most:
1) New comics section - the detail view and the covers view are cool.
2) News section
3) Videos section
and 4) Reviews
These are pretty awesome. The only need I always felt in multiple screens is the need to have it load faster. I do not know what could be the complexity/ limitation but just throwing it out as a feedback.
Once again, keep up the great work. See if you could release a paid version that doesn't load ads and may be throw in some enhancements. I am sure many of us would go for it.
