Asthma self-management app

Project Description

For people living with asthma, managing their condition can be a constant struggle. In fact, of the 1.7 million people with asthma in Ontario, fewer than half have it under control. To help asthma patients better manage their condition, the Ontario Lung Association has developed breathe – a mobile app that helps people with asthma track their symptoms, triggers and medication usage, and provides them with an Action Plan generated by their doctor to help them stay in control of their asthma symptoms.

By integrating asthma data repositories with personal health records and the breathe application, breathe is a novel mobile health app that can provide the opportunity for people with asthma to engage in their individualized treatment plans in hopes of leading to better asthma control.

Through consumer engagement, recognizing key elements of asthma and chronic disease self-management with clinical experts, as well as leveraging current mobile technology, it was envisioned that breathe would enable a person with asthma access to personal health information ‘on-the-go’ empowering them to self-manage anywhere, anytime. Furthermore, integrating with asthma clinics forms a collaborative environment between the individual, caregivers, and providers.

With the information that we gained during the preliminary interviews, I worked with another human factors specialist to create both conceptual diagrams and wireframes for the responsive app. We tested out our paper prototypes to gain feedback from our users. We re-iterated and tested out medium and high fidelity prototypes that were built on Axure to help provide guidance to our final product.


breathe underwent a randomized clinical trial with 400 patients in Ontario from 2012 to 2014. The app was published in the Association for the Advancement of Medical Instrumentation journal in December 2012.
