Loopcam 2.0 is a well-connected mobile hub for all things GIF. Vine has shown us that people will eat up short, looped clips no matter what file format they come in. Still, animated GIFs have one big advantage over their would-be Twitter-endorsed usurpers: they’re far easier to share. Which is just what Loopcam, one of the original GIF-making apps for the iPhone, is emphasizing in version 2.0.
