Back in January, we noted that Loopt was sending around a deck to advertisers showing off a new product . The product was focused on check-in specials (the kind popularized by Foursquare ) and was entirely built on top of Facebook's social graph. Finally, nearly 6 months later, that app is here. Loopt Star is in some ways a simplified version of Loopt's regular location-based service. Rather than being a service that is continually updating your location in the background, the focus here is only on the idea of the check-in. And naturally, those check-ins take place at specific venues -- some of which Loopt has deals in place with to coincide with the launch of the new app. We're talking big, national brands such as Gap, Burger King, and Universal Music.
