Pass the California nail technician exam — first try. California rewrote this exam on April 1, 2026. Safety and Infection Control went from 38% to 50% of the paper, and Skin Care is an entirely new category. Material written before then drills the wrong half of the test. Every question and lesson in this app is weighted to the new outline. BUILT TO THE REAL PAPER • 60 scored questions, 90 minutes, 75% to pass — the mock exam matches it exactly • The same weighting the Board publishes: Safety 50%, Nail Care 22%, Client Consultation and Nail Analysis 18%, Skin Care 10% • The real paper also carries 5 unscored trial questions. The app tells you what to expect. 1,973 QUESTIONS, EVERY ONE EXPLAINED • 1,070 questions in English, 903 in Tiếng Việt • No bare right-or-wrong. Each answer explains why it is right, why the tempting one is wrong, and which state rule decides it • Wrong answers are built from the misconceptions the exam actually traps — not filler TWO LANGUAGES, WRITTEN SEPARATELY • The Vietnamese track is authored for this exam, not machine-translated • It keeps the English term beside each Vietnamese one, because the exam is sat in English • Progress on each track is kept separately 84 LESSONS THAT ACTUALLY STICK • Short readings you can finish between clients, each followed by review questions • Covers pathogens, decontamination levels, implement handling, product safety, nail and skin conditions, and client consultation ASK AI, ON ANY LESSON OR QUESTION • Stuck on a lesson or a wrong answer? Ask, and get it explained in plain language • It answers for CALIFORNIA — where the national textbooks differ, it follows the state • It will tell you when a rule does not exist rather than invent one: California sets no implement soak time, and the tutor says so instead of making a number up • Ask in Vietnamese and it answers in Vietnamese PRACTICE HOWEVER YOU LIKE • Full timed mock exam • Practice by blueprint area • Random sets of 10 to 100 • Every question you got wrong, in one place ABOUT THE SUBSCRIPTION Nails Exam offers auto-renewing subscriptions that unlock every lesson and practice test.

Verdict

The call

Nails Exam and DMVVN both sit at 4.7 stars, but that hides the real split: 100% of DMVVN's written reviews are positive against 60% of Nails Exam's. DMVVN also leads on in-app purchases (none vs 4) and iOS requirement (9.0 vs 15.1). Nails Exam's advantage is ratings volume (492 vs 6). On price, rating, update cadence and ads there is nothing between them.
