Not bad, but instead of finding places I see food, faces and stuff, but really less placed. I am a professional phozographer and need views not macros of trains and hamburger. I wish, user could point out useless photos. This app has to become clear

Yes, that's very unfortunate. With 500px closing their API completely, only Flickr left as a source for images. Flickr isn't very good at sorting and rating images, so you get what Flickr gives. 

I am working on a way to improve images quality, but can't promise it will be delivered in the nearest future
