Voca-Voca turns your everyday reading into a personal vocabulary builder. Highlight any word in Safari, Apple News, or Books, tap Share, and it's saved instantly โ€” with the exact sentence you found it in and the source you found it at. Then proven spaced repetition (flashcard, spelling, and mix modes) brings each word back right before you'd forget it, so the words you meet while reading become words you own for life. Built for avid readers, professionals, and SAT, GRE, and LSAT prep. Never hit a dead end: when a word is too new, too niche, or too slangy for the dictionary, Voca-Voca's AI defines it from the very sentence you found it in. FIND YOUR STARTER WORDS New to the app? A one-minute placement quiz gauges your level, asks what you do and read, and builds a personalized starter set โ€” from Business & Finance to Law & Policy to SAT/GRE prep โ€” so your first practice session starts the moment you open the app. CORE LOOP โ€ข Save words from anywhere. Use the system share sheet from Safari, news apps, books, or any text on iOS. โ€ข Every saved word keeps the sentence where you found it โ€” so the word stays attached to a memory, not floating in a list. โ€ข Spaced repetition schedules each card at the precise interval where you're most likely to forget. Less studying, better retention. โ€ข Spelling mode trains you to write words, not just recognize them. THE COLLECTION โ€ข Search across thousands of words instantly. โ€ข Group by source โ€” see what you collected from each site. โ€ข Sort into folders. โ€ข Track your mastery as words move from "Learning" to "Mastered." CROSS-DEVICE โ€ข Sign in with Apple or Google. โ€ข Words you save on iPhone appear in our Chrome extension on desktop โ€” and back. You read on your laptop, you practice on the train. PREMIUM Free forever, with a generous starter cap. Premium unlocks: โ€ข Unlimited word collection (the free tier caps at 100). โ€ข Premium AI voices in four English accents โ€” American, British, Australian, Indian โ€” for crisp, natural pronunciation. โ€ข Full folder control โ€” choose the default folder for new words and delete folders together with their words. PRIVACY Your words and your data are yours. We never sell anything. Our analytics measure what features people use in aggregate โ€” never the words you save, never the URLs you read. Our privacy policy is plain English at voca-voca.app/privacy-policy.html. Terms of Use: https://voca-voca.app/terms-of-service Privacy Policy: https://voca-voca.app/privacy-policy.html Made by a small team that thinks vocabulary is too important to leave to memorization apps.
