Looks like Google is on a product launch roll. Now they are releasing an iOS social sharing app called "Photovine."
It's invite only for now, but this is the teaser from the website:
A vine is like a constantly growing family of photos connected through a common caption created by you, your friends, and people all over the world. Some examples of vines could be: “What Weekends Are Made Of”, “Secret Stuffed Animal”, “Party People”, or, “Love of My Life”. As people add photos to vines, they tell their own stories about the moments, images, and ideas that define our lives in a way that’s social, creative, and fun.+Christina Azimi
