The application will be very similar to the app, Foursquare. Instead of checking into different retail locations, I want to focus on the nightlife. The app will require the mobile user to create a login profile. This will make it easier to suggest recommendations, and sending out marketing e-mails. The following features I will like to add: GPS, notifications, business profiles, ratings, and reviews. The application will be similar to Foursquare, but with a trendy edge to promote nightlife in different cities.
