Don't just memorize words. Collect them. WoziGrow turns language learning into a visual game. Designed specifically for beginners, every word you learn unlocks a unique, hand-drawn sticker—from a smiling strawberry to a grumpy cat. Why WoziGrow? Most flashcard apps are just text. WoziGrow uses Visual Association to help you learn faster. 1. See the word: A card appears with a cute sticker. 2. Swipe to learn: Swipe Right if you know it, Left if you don't. 3. Build your collection: Mastered words fill your sticker album. Watching your vocabulary grow is oddly satisfying. Key Features: * Visual Flashcards: No boring text lists. Colorful illustrations for every word. * Smart Memory (SRS): We use the Leitner spaced repetition system. Words you struggle with appear more often until they stick. * Beginner Focused: No complex grammar or conjugation. Just the essential nouns you need to survive travel: apple, train, ticket, water. * Home Screen Widgets: Keep your "Always Visible" vocabulary growing even when the app is closed. 17+ Languages Included: Unlock stickers in: * Chinese (Simplified & Traditional) * Japanese (日本語) & Korean (한국어) * Spanish (Español) & French (Français) * German (Deutsch) & Italian (Italiano) * Thai (ไทย), Vietnamese (Tiếng Việt) & Indonesian * Russian (Русский), Polish (Polski) & Turkish * Hindi (हिन्दी) & Portuguese (Português) UNLOCK ALL THEMES (IN-APP PURCHASE) WoziGrow is free to download and use with the Animals theme.
