Most vocabulary apps make you memorize lists. Vocaby lets you build a bigger vocabulary the way you'd actually enjoy: a few swipes a day. Swipe through real words. Each one comes with its pronunciation, a plain-English definition, and an example sentence you'll actually remember. Tap to hear it out loud. Keep the words worth learning, hide the ones you already know. The words you keep come back later, right around the time you'd start to forget them, until they're yours for good. That's the whole idea: words go from "I think I've seen that" to "I use that." What you get: 29,000+ English words, plus a growing Korean set, each with IPA, audio, definitions, and examples. A review system (FSRS) that brings a word back just before you'd forget it, so you study what you need and skip what you don't. Curated decks by topic, so you're not staring at a blank search bar wondering where to start. A word of the day, and a home-screen widget that teaches you something new every time you glance at your phone. Your own words, added in seconds. Type a word and Vocaby fills in the definition, pronunciation, and examples for you. Controls that fit your pace: how many new words a day, how hard you push your memory, and when to get reminded. A warm, paper-like design that's easy to read first thing in the morning or last thing at night. Vocaby is free to start. Premium unlocks the full library and unlimited study. One swipe, then the next. That's how the list gets shorter and your vocabulary gets bigger. Vocaby Premium is an auto-renewing subscription, offered monthly or yearly. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel anytime in your App Store account settings.
