The words you look up don't stick — because you never see them again. AutoVocab puts them on your lock screen, spaced through your day, so you keep meeting your own words until they stay. WORDS COME TO YOU Add a word once and AutoVocab schedules it into your day. Every notification is a tiny lesson — word, meaning, example — read in the two seconds you already spend glancing at your phone. Home Screen widgets keep your current words in sight. No session to start, no app to open. YOUR WORDS, NOT A COURSE No canned word-of-the-day list. Type a word and the definition, phonetic spelling, example and CEFR level fill in from the built-in dictionary. Keep every meaning a word has, each with its own part of speech and level. Already have a list? Import it from CSV in one step. IT KNOWS WHEN YOU'LL FORGET Spaced repetition (SM-2) brings each word back right before it fades, and every word shows its memory strength — so you can see what's about to slip before it does. EIGHT GAMES THAT HUNT YOUR WEAKEST WORDS Quick Quiz, Reverse Quiz, Flashcards, Scramble, Fill the Blank, Match Pairs, Speed Round — and Smart Mix, a round built from the words you're closest to forgetting. Earn XP, level up, keep a streak, collect 24 badges. Or drill one stubborn word until it gives in. HEAR EVERY WORD Clear text-to-speech pronunciation, spoken in the word's own language with the best voice on your device. WORKS OFFLINE. STAYS PRIVATE. Your vocabulary lives on your phone — no account, no server, and your words never leave your device. Optional iCloud backup keeps them safe across your own devices. The only network request is the dictionary lookup you ask for. PERFECT FOR • Exam prep — import GRE, SAT, TOEFL or IELTS word lists via CSV • Language learners collecting words from real life • Readers and word lovers who look words up and want them to stick HOW IT WORKS 1.
