Hi! I'd like to invite you to test Binbine!, a free photo sharing app for dual-image posts.
It's a free service for combining two pics into creative 'diptychs' with optional captions. The app is available on Google Play: https://play.google.com/store/apps/details?id=com.binbine
This format gives endless possibilities of combining photos: before and after, inside and outside, left and right, photo stories, dual-image memes, and so on! Try it and figure out your own variants) You can also easily discover other users' content, follow them, like their posts and exchange comments.
Take a look at the screenshots:
You can 'like' other users' posts and leave comments, follow other users, discover new content in the New tab of your feed and look for the most popular posts in the Best tab. You can also cross-post your diptychs or 'bines' to Facebook and share anyone's post via email, Twitter, G+, and other networks. The app works on smartphones and tablets, in the portrait and landscape modes.
