Everything on the nail technician written exam, in one app. No ads, no subscription, no account — study offline. Every card, every answer and every lesson names the public source it was written from, so you can check any fact yourself. WHAT'S INSIDE 20 lessons — about three hours of reading, broken into short parts you can finish between clients. Each one explains why the rule is the rule, walks a scenario at the table, names the traps that cost points, and checks you before you move on. 440 practice questions with a real explanation on every one, drawn by domain in the same proportions as the published exam outline. Full-length timed mock exams — 100 questions in 90 minutes, marked at the 75% line — with your score broken down by domain so you know exactly what to study next. 690 flashcards on a spaced-repetition schedule. Cards you know come back later and later. Cards you miss come straight back. Label-the-diagram drills for the nail unit, the hand and the foot — tap the matrix, the lunula, the hyponychium, the carpals, the talus. A guide to the practical exam: the seven timed sections, what is graded in each, the kit list with a packing checklist, and the rules. A plain-language guide to getting licensed — which exam your state uses, the hour requirements, how to register, what test day looks like, and what happens if you fail. COVERS THE FULL OUTLINE Infection control and safety · anatomy and physiology of the nail, skin, hands and feet · nail and skin disorders (recognize, then decide) · chemistry of nail products · client consultation and set-up · tools, implements and supplies · the manicure and pedicure · massage · tips, wraps, acrylic, gels and dip · aftercare and clean-down. HOW IT WAS MADE Written from public sources — OSHA, CDC, EPA, FDA and NIOSH publications, state board rules, the published exam content outlines, and open reference works — with every item written against a named source and independently reviewed against it. Found a mistake? There is a report link under every explanation. Study aid for the nail technician licensing theory exam. Not a substitute for your school, a product's directions for use, your state's rules, or medical advice. Not affiliated with, endorsed by, or sponsored by the National-Interstate Council of State Boards of Cosmetology (NIC), any state board, or any testing vendor.
