For watching the Coronavirus, Flu season, or even just to know where people's allergies are flaring up, use the app Sickweather.
The app is an illness crowdsourcing community that gathers information from users all over the world, giving each location a sick score.
Features on the app show users the contagion level and top trending illnesses in your city or travel destinations.
When you or a member of your family is sick, record illness symptoms and temperatures within the app to be used for your own records as well as to contribute to the sick score of your city.
Users can also set up location based notifications with Sickzone Alerts and create groups for local schools, public places, even your place of work.
According to Abby, the app could become more useful as more people in communities begin to use it.
