Motorola Connect is the accessory control and customization app. It was just updated and includes many new watch faces and a new UI. The changelog lists a more intuitive and easier to navigate interface. The new UI is large and bright and matches the Moto G and Moto X Pure Edition. Once you open the updated app you get a carousel of connected apps, and the ability to add new devices. Once you touch a device you will see device options including dock colors, watch location, and the new watch faces. New faces include Dials, Dials II, Refined, and Essential.
