Android/iOS: Today, Flickr received a brand new interface for its mobile app that aims to replicate a lot of the functionality of Instagram, because that's what photo apps do now.
The app includes 14 new filters when you're taking pictures with the camera. You can apply the filters through the viewfinder as you take your pictures so you know what you're getting. You can also manually backup all of these photos to the 1TB of storage that all Flickr users receive.
