The document describes the design of a smoking cessation service called Smokeless. Smokeless uses a connected lighter and mobile app to track smoking consumption data such as number of cigarettes, time, location and cost. It aims to increase self-awareness and provide support to help users quit smoking. The app allows users to set daily goals, care for a virtual pet affected by their smoking, and access alternative activities when craving a cigarette. The goal is to help users achieve long term smoking cessation through collecting personal smoking data and gamified support tools.
