The name of that site is Politico. Don’t you know there’s no politics allowed in this thread? Now you’ve ruined it for everybody.I found this site extremely informative. It keeps track of not only the number of cases in every state, but the number of tests that are being done. Seems to be pretty accurate based on Iowa's numbers.
