240+ realistic NCLEX-style med math problems with instant grading and a step-by-step solution for every answer — so the math is second nature before it matters most. Free on iPhone and Android.
DoseRightRN is a mobile app that helps nursing students practice dosage calculations. Each round is 10 clinical-style problems; you solve on a built-in keypad, get graded instantly, and see the formula and every step of the worked solution.
It is made for students in ADN, BSN, accelerated BSN, and LPN/LVN programs who need to pass a dosage calculation or med math exam, and for anyone preparing for the NCLEX-RN or NCLEX-PN. Instead of a general question bank, it drills one skill until it is automatic.
New to the math? Read our free dosage calculation formulas guide with worked examples.
Focused practice that mirrors the exam and the clinical floor — no fluff, no distractions.
Clinical scenarios modeled on the NCLEX and real practice — tablets, oral liquids, IV pump and gravity rates, unit conversions, pediatric mg/kg, and reconstitution.
Every answer is graded the moment you submit, with the correct solution shown right away so you learn from mistakes immediately.
See the formula, the substitution, and each step of the math — so you understand the why, not just the answer.
Proper rounding to the tenths and hundredths place — practice the exact way you'll calculate and chart in clinical.
No sign-up, no login, no Wi-Fi needed. Open the app and practice on the bus, between clinicals, or anywhere with weak signal — with a daily streak to keep you going.
A 30-day activity heatmap and per-category accuracy show exactly where you're strong and what to drill next.
Jump straight into the type of problem you need, or hit Start Mixed Drill to sharpen everything at once.
Get it right or wrong, you always see the full worked solution — formula, substitution, and the final administration.
Consistency is the key to clinical precision. Your journey view keeps you motivated with streaks and a clear accuracy score.
ADN, BSN, accelerated BSN, and LPN/LVN students facing a dosage calculation exam, med math competency test, or pharmacology course.
Fast, focused reps on the calculation questions that show up on the NCLEX, to pair with your main question bank.
A quick refresher before med pass in clinicals, and for new grads and nurses returning to practice who want their med math sharp again.
No account, no setup. Open the app and go.
Choose tablet dosage, IV rates, pediatric dosing — or run a mixed drill for a full workout.
Work the problem with the built-in keypad and check your answer with one tap.
Review the step-by-step breakdown, build your streak, and watch your accuracy climb.

DoseRightRN is a dosage calculation practice app for nursing students, available free on iPhone and Android. It drills the med math tested in nursing school and on the NCLEX — tablet and liquid dosing, IV flow rates, IV drip rates, unit conversions, pediatric weight-based dosing, and reconstitution — with 240+ realistic problems, instant grading, and a step-by-step worked solution for every question.
DoseRightRN is built for exactly this. Unlike broad NCLEX question banks, it focuses only on dosage calculation, so you get unlimited short reps of the problem types that cause the most dosage-exam failures, with the formula and every step shown after each answer. It is free to start on iPhone and Android, needs no account, and works offline.
Six categories: Tablet & oral liquid dosing (Desired / Have × Vehicle), IV flow rate (mL/hr for infusion pumps), IV drip rate (gtts/min by gravity with 10, 15, 20, or 60 gtts/mL tubing), unit conversion (mg/mcg/g, mL/L, lb/kg), pediatric weight-based dosing (mg/kg, including divided daily doses), and reconstitution (powder concentration and volume to draw up).
Yes. Problems are written as clinical scenarios in the style of NCLEX-RN, NCLEX-PN, and nursing-program dosage calculation (med math) competency exams, and answers are graded with standard nursing rounding conventions. It is a focused drill tool, so many students pair it with their course textbook or a full NCLEX question bank.
Yes. The free version includes daily practice rounds in Tablet Dosage, IV Flow Rate, IV Drip Rate, and Unit Conversion, plus step-by-step breakdowns, streaks, and accuracy tracking, supported by ads. You can earn extra rounds by watching a short ad. The optional DoseRight Pro subscription unlocks unlimited rounds, the Pediatric and Reconstitution categories, and removes ads. Current pricing is shown in the app.
Yes. DoseRightRN is available on the Apple App Store for iPhone and on Google Play for Android.
Yes. Practice questions, grading, and breakdowns run on your device, so you can study without an internet connection — on a commute, between clinicals, or in a hospital with weak signal.
No. There is no sign-up or login. Open the app and tap Start. Progress and streaks are saved on your device with an anonymous identifier.
Standard nursing conventions: tablets and mL volumes to the tenths place, infusion pump rates to a whole mL/hr, gravity drip rates to whole gtts/min (you can't give part of a drop), and pediatric weight-based doses to the hundredths place.
On iPhone: Settings → your name → Subscriptions → DoseRight Pro. On Android: Google Play → profile icon → Payments & subscriptions → Subscriptions → DoseRight Pro. Canceling stops future renewals; you keep Pro until the end of the current billing period.
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.
