I'm a pharmacy student, and I built RxAce because I wanted a study app that gets straight to the point — no subscriptions, no accounts, no ads. Pay once, study anywhere, even offline. WHAT'S INSIDE • NAPLEX-STYLE PRACTICE — 60 original exam-style questions across the five areas students struggle with most: Calculations, Pharmacotherapy, Biostatistics & Literature Evaluation, Compounding, and Medication Safety & Counseling. Every question includes a full worked explanation, because the explanation is where the learning happens. • 225 DRUG FLASHCARDS — the brand names, generics, drug classes, and indications you actually see in practice and on the exam. Tap to flip, filter by drug class, and let the built-in mastery system resurface the ones you miss. • QUICK QUIZZES — 10-question rounds: brand→generic, generic→brand, drug→class, and sig codes. Instant feedback on every answer. • SIG CODE REFERENCE — 69 pharmacy abbreviations (frequencies, routes, dosage forms, measures) in a searchable list. Great for interns and technicians too. • PROGRESS TRACKING — accuracy by category, drugs mastered, a 7-day study chart, and a daily streak to keep you honest. Everything runs on your phone. No sign-up, no data collection, no internet required. One price, all of it, forever. Made by a pharmacy student, for pharmacy students. Good luck — you've got this.
