这不是一款“多做题”的学习 App， 而是一套真正判断你是否学会的智能学习系统。 在这里，AI 不只是出题，而是先理解知识、拆解考点，再根据你的记忆状态动态安排练习与复习。 每一个知识点，都会被拆成清晰、可掌握的最小考点； 每一道题，都会服务于“真正记住”，而不是刷完就忘。 你不需要自己规划复习，也不需要反复猜“我到底学没学会”。 系统会结合你的答题表现与科学的记忆曲线，自动判断哪些内容已经稳定进入长期记忆，哪些还需要巩固。 当一个知识点被标记为“已掌握”， 意味着它已经经过多次间隔验证，而不是一次侥幸答对。 你看到的，不是题量，而是进度； 你追求的，不是速度，而是完成。

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.
