Most vocabulary apps make you memorize lists. Vocaby turns it into a few quiet swipes a day — until words go from “I think I've seen that” to “I use that.”
Swipe to learn
Learn words the way you'd actually enjoy
No endless lists to grind through. Swipe right to keep a word worth learning, left to hide one you already know. Each card shows the word, its pronunciation, a plain-English definition, and an example you'll remember.
- Tap to hear every word and example out loud
- IPA pronunciation on every card
- Undo a swipe any time
Never forget a word
Spaced repetition that knows when you'll forget
Vocaby uses FSRS, a modern spaced-repetition algorithm. Rate a word Again, Hard, Good, or Easy and it schedules the next review for the exact moment you're about to forget — so you study what you need and skip what you don't.
- Reviews timed to the edge of forgetting
- Or switch to fast, on-demand review
- Watch your streak grow day by day

FAQ
Frequently asked questions
What is Vocaby?
Vocaby is a vocabulary-building app for iPhone. You swipe through real English words — each with its pronunciation, audio, a plain-English definition, and an example sentence — keeping the ones worth learning and hiding the rest. A spaced-repetition system then brings each kept word back right before you'd forget it.
How does Vocaby help me remember words?
Vocaby uses FSRS, a modern spaced-repetition algorithm. After you rate a word Again, Hard, Good, or Easy, FSRS predicts when you're about to forget it and schedules the next review for that exact moment. You study only what you're at risk of losing, so words move into long-term memory faster.
How many words does Vocaby have?
Vocaby includes more than 29,000 English words, each with IPA pronunciation, audio, definitions, and example sentences — over 167,000 examples in total. There's also a growing Korean set and support for seven languages, so you're never short of new words to learn.
Is Vocaby free?
Yes. Vocaby is free to download and start learning, with a daily set of new words, reviews, and the word-of-the-day widget. Vocaby Premium — an auto-renewing monthly or yearly subscription — unlocks the full word library, unlimited study, every topic deck, and custom card themes.
Is Vocaby good for SAT, TOEFL, GRE, or IELTS prep?
Yes. Vocaby has curated decks for exams like IELTS and TOEFL alongside academic and topic sets, so you can focus on the words a test actually rewards. Because reviews are spaced, you retain exam vocabulary through test day instead of cramming and forgetting.
Does Vocaby have audio and pronunciation?
Every word in Vocaby shows its IPA transcription and plays audio pronunciation with a tap, so you learn how a word sounds as well as what it means. Example sentences are spoken too, which helps you hear each word used naturally in context.
Can I add my own words to Vocaby?
Yes. Type any word and Vocaby auto-fills the definition, pronunciation, part of speech, and example sentences for you, so adding a word you ran into takes seconds. Your own words join the same spaced-repetition reviews as the rest of your collection.
What languages does Vocaby support?
Vocaby supports seven languages — English, Italian, Chinese, Spanish, French, Portuguese, and German — with a growing Korean set. You choose your language during onboarding and swipe through every word in it, complete with pronunciation, definitions, and examples.
