The Smoke Sense mobile app is designed to pilot a citizen science study about the impacts of wildfire smoke exposure on health. Citizen scientists can use the app to learn about wildland fires and smoke health risks in their area. They can report their health symptoms, and the range of actions they are able or willing to take to improve their health condition or lower their exposure. Users will earn badges each week they participate.

If successful, data gathered through Smoke Sense will help EPA researchers and communities determine how smoke impacts our health and productivity and gain important insights needed to develop health risk communication methods during smoke days.

The findings from the study will be peer-reviewed for scientific publication and published on the EPA website. Public health officials and air quality managers can use the results to develop strategies to protect public health from wildland fire smoke.

The pilot will be conducted during the 2017 wildland fire season until the end of October. At the end of the study, the Smoke Sense app will go offline temporarily for updates. Smoke Sense app user identities will be anonymous and non-identifiable.

My boyfriend works for the company that made this app on behalf of the EPA.
It has been an invaluable tool for monitoring our air quality during the Sonoma and Napa fires. It helped us determine where we should go to find cleaner air to help with asthma and pets. A big thank you to the EPA and to Sonoma Technology Inc!

Constantly crashes

Have been attempting to use his app for a few days and it takes nearly 2 minutes to load then crashes shortly after opening. I was really looking forward to using this tool as I have been dealing with severe smoke conditions from the Camp Fire and was hoping to utilize this app to find safe places to escape out of the smoke.

Can’t use it without being in research study?

I don’t know if it’s a good app or not because it wouldn’t allow me to access anything without giving my own personal information to become part of their research study. At last not as far as I could tell. Delete.
