I have had this app on my phone for a long time and never taken the time to explore it. So much of this information I look for online in different places — now I realize it's all been in one place!

VERIFIED APP REVIEW
It gives graphs of CDC data for flu, RSV, and COVID for your area, heat and storm alerts, air pollution too. I use it almost daily. Also if I go on a trip I can look at flu or COVID levels where I'm going. It's the best app ever.

VERIFIED APP REVIEW
Easy to use and allows me to monitor local outbreaks within my county! I was skeptical about having to pay something or see ads but I didn't need to pay anything.
