Pass your phlebotomy or medical assistant certification.

One app. Seven certifications. One-time purchase, no subscription.

ScrubCert is an iPhone study app for the certification exams that allied health students actually sit. Each one has its own page here, with the format, the domains and their weights, the passing score and what it takes to renew:

The seven exams

NHA CPTCertified Phlebotomy Technician (CPT)ASCP PBTPhlebotomy Technician, PBT(ASCP)NHA CCMACertified Clinical Medical Assistant (CCMA)CMA (AAMA)Certified Medical Assistant, CMA (AAMA)AMT RMARegistered Medical Assistant (RMA)NHA CMAACertified Medical Administrative Assistant (CMAA)NCCT NCMANational Certified Medical Assistant (NCMA)

The CMA (AAMA) outline changes in July 2027. If you are sitting that exam, read what moves and what to study before you pick a study plan.

Built the way the exam is built

Every practice test carries the same number of scored questions as the real exam, the same time limit, and the same number of questions per domain that the certifying body publishes in its current test plan. When a certifying body publishes a new outline with a start date, the app carries both and lets you choose the one you are sitting.

Every explanation names its source

Explanations say why the correct answer is correct and why each of the others is not — and they rest on public authorities you can open yourself: the CDC, OSHA, the CLIA regulations, the FDA, the Centers for Medicare & Medicaid Services, the National Institutes of Health and its National Library of Medicine, and the World Health Organization. No textbook is reproduced, and no real exam question is reproduced.

Read how we write the questions and which sources we use and which we refuse.

Free, with no account and no purchase

The complete guide to each of the seven exams: format, timing, domain weights, scoring, what to bring, and what it takes to renew the credential afterwards.
Worked calculation problems and calculators: dosage, weight-based dosing, unit conversions, body mass index, ECG heart rate, blood volume.
The glossary and the pocket reference tables, each entry with its source.
Three practice questions from every domain, with full explanations.
Five new questions every day, and a ten-question diagnostic you can repeat every week.

What is free stays free. Nothing is taken away after a trial period, because there is no trial period.

English and Spanish

The interface, the exam guides and every question with its explanation are available in both languages. Inside any question you can flip that one question between English and Spanish with a single tap — the easiest way to learn the English term you will meet on exam day.

No subscription. No ads. No account. No internet needed.

Buy one certification, buy the CCMA + CPT pair, or buy all seven — each one a single payment that never renews. Everything you do stays on your iPhone: nothing is collected, and nothing is sent anywhere.
