This is amazing...........Free, from the NYTimes.....enter the counties, and/or states, where you want to keep up with covid data. Then bookmark the site, and all your places will show up whenever you want.
It's free, but if you do get a pop up at the bottom just close that, it's not requiring a subscription, just suggesting one, lol
