Urban Senegalese women face challenges in managing asthma effectively due to limited access to healthcare and insufficient health literacy. A mixed-method approach was employed, including surveys to assess baseline knowledge and preferences among participants, followed by the implementation of an asthma self-management app. Data were analysed using descriptive statistics and thematic analysis. Participants showed significant improvement in understanding asthma management (85%) and reported better adherence to prescribed medications (60% increase) after app use, with notable improvements in nighttime symptom control (32% reduction). The digital health platform successfully enhanced women's knowledge about asthma and improved their ability to manage symptoms effectively. Further research should explore scalability of the intervention across different urban Senegalese communities and evaluate long-term sustainability. Asthma, Digital Health Platforms, Behaviour Change Strategies, Urban Senegal Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
