ExSnus: A Persuasive Mobile Health Application for Snus Cessation

Paper in proceeding, 2025

The use of snus among Swedish youth is increasing, becoming a growing public health concern due to its associated health risks. To help individuals quit addictive behaviours such as snus consumption, mobile health applications have emerged as accessible and cost-effective tools. This project presents ExSnus, a mobile application prototype designed to support users in quitting snus by employing strategies based on a persuasive systems design framework. The application combines social interaction and self-monitoring to address key factors influencing snus use, such as social influence, cultural normalization, and health concerns. This approach ensures that ExSnus not only supports behavioural change but also provides an accessible tool tailored to the needs of young users.
