If you're looking for a way to share your Selfies and include more of what you are doing and seeing, Frontback is an awesome app. It's the perfect way to share your selfie and capture the mountains, trails, concert or party that you are at all in one photo.
Frontback is a social network, so you will need to join up, but you can also save these special photos to your phone so that you can share them to Facebook or send to someone.
There are many options to change your photos around, and you don't need to take the photos at the same time. You just take one with the front camera and one with the rear.
