@Instagram @Pinterest …You See This?: @Tumblr Launches NEW Photo App [PHOTOS]
The app is super simple to use. You can use pre-existing photos from your camera roll or take new ones, and then group them together to make a photoset.
Once you organize your set of photos, you can share them on a website with its own unique link, or share with friends on social networks including Tumblr, Facebook and Twitter.
Intriguingly, it uses a new website, photoset.com, instead of tumblr.com.
