As you might expect from its simple name, 'Selfies' is a dedicated Android app for selfies with one large feed showing all of the photos taken with the app. The Selfies app is a project by Automattic, the same company responsible for Gravatar and Wordpress. Since you're able to upload photos, add captions and react to content by other users with your own images, the app is like a cross that's somewhere between Instagram and Snapchat. The app is extremely new and was developed over the course of a few weeks, so for now, the only way to browse content is a through the one large feed, although there are plans for better filtration soon.
If you're someone who would consider themselves a little selfie-obsessed, this is one community that would benefit from having you constantly post content—plus, it's totally free to download.
