Purchases and subscriptions

Do I have to pay to use the app?

Yes. RD Exam Prep: Dietitian CDR is a paid app with no free tier. After the onboarding questions you choose a plan: Monthly ($9.99/month), Yearly ($49.99/year with a 3-day free trial), or Lifetime Access ($99.99 one time). All three unlock everything.

How does the 3-day free trial work?

The trial is on the yearly plan. You get three days of full access at no charge. If you do not cancel at least 24 hours before the third day ends, it converts into a paid year at $49.99. Cancel any time from your Apple Account settings, or from Settings → Manage Subscription in the app.

I paid but the app still shows the paywall.

Tap Restore Purchases - it is on the paywall itself and also in the Settings tab. Make sure you are signed in with the same Apple Account you bought with. If it still does not unlock, check your internet connection (restoring needs to reach the App Store once) and email us.

How do I cancel?

Open the app, go to the Settings tab, tap Manage Subscription. Or on your device: Settings app → your name → Subscriptions → RD Exam Prep: Dietitian CDR → Cancel Subscription. Cancelling stops future renewals; the period you already paid for runs to its end.

How do I get a refund?

Apple handles all billing and all refunds for App Store purchases; we cannot issue one directly. Request it at reportaproblem.apple.com.

Can I use my purchase on my iPad too?

Yes. Sign in on the iPad with the same Apple Account and tap Restore Purchases. Lifetime Access and subscriptions both carry over.

Using the app

Does it work offline?

Yes. The entire question bank is bundled inside the app. Once it is installed you can study anywhere. The network is only used to talk to the App Store about your purchase, or if you tap an outside source link.

How is the readiness score calculated?

It blends how much of the bank you have covered with how accurately you are answering, weighted by how much each domain counts on a national-format mock. It is a study signal, not a prediction of your actual exam score.

Is the mock exam like the real licensing exam?

It offers up to 110 questions with a time limit you can match to your study focus (about 4 hours for Licensed/Certified Residential, up to 6 for Certified General), and domain weighting modeled on commonly cited AQB-aligned content outlines. Exact question counts, timing, and passing score are set by your state and its testing vendor — always confirm those with your CDR.

How does spaced repetition work here?

Every flashcard gets graded Missed It, Hard, or Easy. Missed cards come back in about 10 minutes; cards you nail get pushed further and further out. The Review tab always shows what's due.

Can I reset my progress?

Settings tab → Reset all progress. It clears your answers, streak, bookmarks, flashcard progress and mock history. It cannot be undone.

I think an answer is wrong.

Email us the question and why. We take accuracy seriously and will review it for the next content update.

About the content

Every question and explanation is original and written by our team. Exam-format facts (question counts, timing, testing vendors) are informed by publicly available information from The Dietetics Foundation and the Dietetics Subcommittee. CDR concepts are tested only in original, paraphrased language — no CDR text is reproduced anywhere in this app. This app is an educational study aid, not dietetics or legal advice, and is not a substitute for your state's required coursework.
