Perry vs Spirkz

Perry is an offline AP exam coach that runs entirely on your phone. No account, no cloud sync, no ads, no tracking — your practice history and any AI tutor chats stay in local storage on your device. WHAT'S INCLUDED, PER SUBJECT • A diagnostic to see where you stand, and a free unit to try the app risk-free • Quick, domain, and adaptive practice drills across every unit • Full-length mock exams with timed MCQ and FRQ sections, a break, and composite scoring • Graphs and data tables in science, statistics, calculus, and economics questions • Free-response (FRQ) practice with rubric-based self-scoring • Spaced review that resurfaces what you're about to forget, powered by FSRS (a modern spaced-repetition scheduler) • Confidence-first practice — rate how sure you are before the answer is revealed, so overconfidence shows up in your stats instead of on exam day • An honest readiness estimate shown as a range, with how much practice it's based on • Local backup and restore, so your progress can move with you to a new device 25 AP SUBJECTS AP Biology, Chemistry, Physics 1, Physics C: Mechanics, Calculus AB, Calculus BC, Statistics, US History, World History, European History, US Government, Comparative Government, English Language, English Literature, Psychology, Microeconomics, Macroeconomics, Environmental Science, Computer Science A, Computer Science Principles, Human Geography, Spanish Language, French Language, Art History, and Music Theory.

Try up to three subjects at no cost, complete one full-length mock exam per subject for free, and back up your progress at no charge. PERRY, AN ON-DEVICE AI TUTOR Full Access adds Perry, a tutor model that runs on your device (an optional download, roughly 2.7 GB over Wi-Fi). Ask Perry why an answer is wrong or get coaching on free-response strategy — the conversation never leaves your phone, because there's no server to send it to. FULL ACCESS A single one-time purchase, Full Access, unlocks every subject's full question bank, unlimited mock exams, Perry, and AI-assisted FRQ scoring. No subscription, no recurring charge. Schools and groups issued an access code can enter it in Settings instead of purchasing. HONEST ABOUT WHAT IT IS Perry is a study tool. Its FRQ feedback — whether self-scored against the rubric or AI-assisted — is an estimate meant to guide your practice, not a substitute for your teacher's grading or the real exam.
