RD Exam Prep: Dietitian CDR is a paid app with no free tier. A subscription or the lifetime unlock is required to use it. All prices are in US dollars and may vary by storefront.
Every question, explanation, and Exam Info summary is original and written by our team, informed by publicly published, non-copyrighted information about exam structure from The Dietetics Foundation and the Dietetics Subcommittee. This app tests CDR concepts only, in original language — it does not reproduce any CDR text. This app is an educational study aid. It is not dietetics, legal, or professional advice, and it does not substitute for your state's official pre-licensing coursework.
