Come holiday shopping, you mean business. And post-holidays, when retailers have their deepest sales, shopping isn't a pastime; it's an art. If this is you, your iPhone, iPod Touch or iPad can guide and entertain you with Snapette, a new location-based photo-sharing shopping app. With GPS technology, Snapette allows users and retailers to share current finds and inventory and where to get it, right there, right then.

Instagram fans will have a field day putting pretty window shopping photos to good use. It's simply fun browsing the uploads, which you can Like, Comment and Share. The simple interface allows you to search by brand, store or description or by what's New, Near and Hot.

But the real thrill is the ability to preview what's in-store nearby. Browse Heidi Says while at brunch on Fillmore and if you see something you like, you can sashay over and try it on. Retailers have joined the conversation by uploading real-time inventory and sales.

Nationwide sales are also listed so you can see what's happening at Saks Fifth Avenue, J.Crew and Anthropologie; this can allow for comparison shopping to see if a better deal can be had online. If you're taking a trip or are curious to see the latest shopping inspirations worldwide, Snapette shares that too. A built-in map and directions help you get to your target.

Founded by two Harvard alums who adore fashion, Snapette is inspired by the social act of shopping, only it takes shopping into another social realm and then back onto the sidewalk.
