City2/CDO is a free Android app developed by Emplate ApS in the Lifestyle category, specifically for shopping. The app offers two main features: earning points and following favorite stores. Users can earn points by checking in via the app every time they visit City2 or Copenhagen Designer Outlet. A maximum of one check-in per day is allowed, and every check-in earns 10 points. These points can be redeemed for prizes, gift cards, or other rewards through the app's point shop.

In addition to earning points, users can also follow their favorite stores in the two shopping centers. By doing so, they can stay updated with the latest news, inspiration, and offers from their preferred stores. The app also allows users to avoid receiving unwanted notifications from stores they are not interested in. The stores frequently update the app with relevant news and offers, making it easy for users to stay up-to-date with their favorite stores. Overall, City2/CDO is a valuable app for shoppers who want to earn rewards and stay updated with their favorite stores' latest news and offers.
