Hello, Smoke Sense Citizen Scientists! Starting on December 8, 2024, the Smoke Sense app will be unavailable for use. Smoke Sense: 4.0 Level UP is under development and will have new and exciting features to help you track and prepare for wildfire smoke. Read more about Smoke Sense Level Up and check for updates on the EPA website. We look forward to seeing you soon! 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.

Hopefully it will contribute to research and also cause Puget Sound Clean Air agency to increase their Enforcement of wood-burning pollution ### 1/5 — Worthless *2024-09-09* Sorry to say this app is basically worthless. Does not reflect the air quality it’s linked to. For example, today the air is extremely bad, low visibility, getting worse by the hour. Purple Air rates it 168 which seems right. Smoke Sense lists it 61. Pathetic. ### 1/5 — Sorry example of an app *2024-07-28* Has hardly ever worked for me. Sometimes it's not displaying anything past the splash screen then it's asking for a lot. And I mean a lot. Of preferences. ### 1/5 — Useless *2023-08-08* Downloaded this app to test it out as it is in guidance for air quality during wildfires. Was hopeful I could push it out to my community during a close wildfire affecting air quality. Was extremely disappointed to find out that it doesn’t work. We have air quality alerts for our area and this app does not pick up on it. Either fix the app or get rid of it because it’s not achieving its goal of providing help to those that need it. ### 1/5 — Crashes constantly *2023-02-19* Map feature no longer works. Crashes whenever you try to look at the map. ### 2/5 — Maps load now but future smoke overlay is missing *2022-08-26, version 3.3.1* This was one of the most helpful features. The apple and android maps now load but there is no option to choose future smoke dispersion. The smoke plumes in now view is limited because that view does not forecast movement or show if it is at ground level. Please fix ASAP. ### 2/5 — Great idea but… *2022-07-26* tabs at bottom are basically unreadable simply because the text/icons are gray on a medium blue background. Contrast, please? Black on blue maybe? Also loading basically anything takes many... long... seconds. Call me spoiled but no other app i use does that so much. ### 1/5 — Why is the server crashing? *2022-07-06, version 3.0.1* Been crashed >2 weeks. We’re in the middle of fire season and need it to see smoke areas Otherwise when it’s working rely on this app ### 5/5 — Bug fixed *2020-09-19* A previous reviewer reported crashes after loading. Works fine for me! ### 1/5 — Does not work. *2020-09-16* Upon opening the app I am asked to consent to a study that is supposed to be voluntary but you don't get an option to opt out. I agreed and filled out the survey. Then the app crashes. Try opening again and it continues to crash. Same thing over and over. Don't download the app. Waste of time. ## Frequently asked questions about EPA Smoke Sense ### What does the Smoke Sense app do?
