No. The app works without sign-up or login. Just open it and tap Start to begin practicing. Your progress and streaks are tied to an anonymous identifier stored on your device.
DoseRightRN is free to use and supported by ads. You get a set number of practice rounds each day at no cost (plus extra rounds for watching a short ad) in Tablet Dosage, IV Flow Rate, IV Drip Rate, and Unit Conversion. The optional DoseRight Pro subscription adds unlimited rounds, the Pediatric and Reconstitution categories, and removes ads.
On iPhone, the subscription is billed through your Apple ID, so it's managed in iOS Settings, not in the app:
On Android, it's billed through Google Play:
Canceling stops future renewals; you keep access until the end of the current billing period. Refund requests are handled by Google Play or, on iPhone, by Apple at reportaproblem.apple.com.
Make sure you're signed in with the same Apple ID or Google account used for the purchase, then use the Restore Purchases option in the app. If ads persist, email us with the date of purchase and we'll sort it out.
Manage the App Tracking Transparency permission anytime in iOS Settings → Privacy & Security → Tracking. You'll still see ads if you decline — they'll just be non-personalized.
No. DoseRightRN is a study and practice tool for nursing students and 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.
