Cool app! I think this app could make Steem more accessible to people!
I just tried it out and here's something I noticed:
for this post https://steemit.com/photography/@shieha/b-and-w-photo-contest-entry-animals-fluffy-egret-ii it showed the first link to an image as the preview image inside the app. But if you look in the post, the first image that you actually see is the black and white photo, not the colored one.
Just something for you devs to consider :)
