Frequently asked

Do I need an account to use DoseRightRN?

No. The app works with no sign-up or login. Just open it and tap Start. Your progress and streaks are saved on your device with an anonymous identifier.

Is DoseRightRN good for NCLEX prep?

Yes. The problems are modeled on NCLEX-style dosage calculations and clinical scenarios, with the same rounding conventions you'll use on the exam and on the floor.

How does the free version work?

DoseRightRN is free and supported by ads, with a set number of practice rounds each day. The optional Ad-Free subscription ($2.99/month) removes ads for uninterrupted study.

How do I cancel the Ad-Free subscription?

It's billed through your Apple ID, so manage it in iOS Settings → your name → Subscriptions → DoseRightRN Ad-Free. Canceling stops future renewals; you keep ad-free access until the end of the billing period.

Is this a substitute for clinical judgment?

No. DoseRightRN is a study and practice tool. It is not intended for use in patient care or to make real clinical dosing decisions. Always follow your institution's protocols and verify with a licensed professional.
