Here are my initial impressions when opening the apps for the first time. Not sure what the three icons are for at the bottom. Heart is not a good choice for "currently treanding', and neither is the down arrow in the box for "latest submission". I thought these were for favorite and download respectively.

I also didn't like the checkmark icon to go back when viewing an article.

Otherwise, I like the little animations, and everything runs smoothly. Good job.
