From Yakshna Solutions:
The Loop answers the age old question of "what are you doing tonight?" by providing an event-based platform that filters the events in your area by preferences and interests. From big concerts to intimate house parties, The Loop allows the user to figure out what they could be doing that night or the next day through a stream of events that are distinguished by certain categories. Not only are you able to find events for yourself, but you can easily keep your friends in The Loop by sharing any of the found events with them. Seeing what's coming up is only half the fun, users are able to create their own events that they can make public or private. Beyond that, any user can sync an event of interest to their iCalendar so that they can be reminded of the event and able to maintain their daily schedule. It's cool to see what just happened through Facebook, Twitter and Instagram, but The Loop allows you to see what's coming up.
