Photovine is Google's latest iOS app and it's best described as a photo-sharing app with a public twist. Unlike Instagram which lets you share your stylized mobile photos with your friends and followers, Photovine ditches the filters and has a much more public slant.
You publish your photo with a theme, caption or category and it becomes a vine. Your vine can be as simple as "photographs of ice cream" to as abstract as "the color orange." Once you create a vine, other people can contribute to that vine and you can watch it grow. Likewise, you can browse other vines and add your own photo. Once your photo is attached to a vine, it becomes public and can be seen on that vine and on your profile.
Photovine was developed by Slide, a company Google acquired
