Povio is an Instagram style app that markets itself as an instant "Point of View" (POV) photo sharing tool to let your friends know what you're doing.
Instead of a feed, it requires you to "Ping" friends with a real-time point of view (POV) photo. All photos are deleted after 24 hours and there's no clutter such as galleries, feeds or profiles.
You can comment and "Like" photos and it may be useful for small groups of friends but otherwise there are no compelling advantages over Instagram.
