A great tool!

A GREAT pocket reference I've used daily for years but just now getting around to writing a review.

Previously free calculators now require subscription

I have used this app for years. However, the ascvd risk calculator, which use to be free, now requires a premium account. This calculator is free in so many other apps. Will delete this app and use an alternative. I understand an app needs to make money, but provide an option with ads versus abruptly cutting off busy providers in the midst of their clinic without a heads up.
