Afterlight is a great new app for Android photographers now available in the Google Play Store. Afterlight enjoys a ton of popularity on iOS thanks adjustable filters, fine-tuning tools, textures, and cut-out frames.
For $0.99 you get 59 filters, 66 textures, and 77 artistic frames. If those aren't enough, you can always pick up more through in-app purchases.
Afterlight is particularly well-suited for sharing snaps out to Instagram, though you can export your final compositions however you like.
