500px is one of the most awesome sharing sites around. There is seriously no better place for connect with other photographers around the globe and getting inspiration at the same time.
The two stars is for the app being so buggy. I mostly use it on my iPad Pro and I cant remember the last time I browsed my feed without it eventually shutting down on me.
Again great site, Ive had an awesome account for four years now, but the app for iPad Pro is not stable and needs improvement.
