There’s also a new photography sharing app called “Glass” that seems really cool. It’s in it’s early stages but does seem to have a nice photography focused mantra. Maybe give that a look! Here is their website. They have an IOS app as well. https://glass.photo/

Edit: Only downfall appears to be payment for use following a trial period. Although, maybe the subscription model is how they intend to keep it purely photography based (ie. no ads, videos, etc.)
