So easy to use!

I am not what might be called an “Intuitive” when it comes to data organizing apps. But CDC made me feel like maybe I’m finally growing some chops! The app could easily have a separate portal named “Cleanup Duplicate Contact for Dummies” to appeal to a senior crowd, of which I am part. I highly recommend.
