단어장 첫 페이지만 새까맣죠? 어차피 까먹을 단어, 이제 '노동'이 아닌 '학습'을 하세요. 영어 고수들이 공통적으로 말하는 비밀, '어원'으로 단어를 이해하면 억지로 외울 필요가 없습니다. 솔직히 그동안의 단어 암기, 비효율의 끝판왕이었죠? 밑 빠진 독에 물 붓는 듯한 공부에 지친 당신을 위해, 가장 과학적인 어원 학습 솔루션을 만들었습니다. • 하나의 어원으로, 단어의 지도를 그리다 하나의 어원(spect=보다)만 제대로 이해하면, respect, inspect 같은 단어들이 포도송이처럼 함께 엮여 이해됩니다. 따로 외우지 않아도 머릿속에 체계적인 단어 지도가 그려집니다. • 뇌를 속이는 얕은 암기는 이제 그만! 무작정 외운 단어는 금방 사라지지만, 원리를 이해한 단어는 절대 당신을 배신하지 않습니다. '이래서 이 뜻이구나!' 무릎을 탁 치는 진짜 이해의 순간을 경험하세요. • 불필요한 '시간 낭비'를 없애는 집중 학습 아는 단어를 복습하는 '시간 낭비'는 이제 그만. 시스템이 당신의 취약점을 정확히 파악해, 헷갈리는 단어와 어근만 집중적으로 공략하게 해줍니다. 약점에만 집중하기에 가장 빠른 실력 향상이 가능합니다. • 지루할 틈 없는, 입체적인 테스트 시스템 단순한 단어-뜻 매칭을 넘어, 스펠링 퀴즈와 문맥 속 쓰임을 익히는 예문 완성 퀴즈까지. 다채로운 테스트를 통해 배운 단어를 완벽한 당신의 것으로 만드세요. • 뇌과학 기반의, 절대 잊지 않는 복습 설계 열심히 외운 단어도 시간이 지나면 희미해지는 것은 당연합니다. 저희는 뇌의 망각 곡선 이론에 따라, 당신이 단어를 잊어버리기 직전의 '최적의 타이밍'에 복습을 유도합니다. 내가 외운 단어가 장기 기억으로 자동 전환되는 과학적인 시스템을 경험하세요. 더 이상 비효율적인 단어 암기에 스트레스받지 마세요. 가장 압도적으로 효율적인 단어 학습법, 지금 바로 시작해보세요. 이용 약관: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ 개인정보처리방침: https://www.hanbangedu.co.kr/%EB%BF%8C%EB%A6%AC%EA%B9%8A%EC%9D%80-%ED%86%A0%EC%9D%B5%EB%8B%A8%EC%96%B4

ChatGPT gives you answers and you forget them an hour later. Tutorials are fun until you can't recall a thing. CodeStudy makes you make the answer — and remember it. CodeStudy is an AI coding tutor that teaches with the Socratic method. Instead of dumping code on you, it asks the right questions until you figure it out yourself. The "aha" moment is yours, not the AI's. That's why it sticks. Pick your track: • Swift / iOS — for app developers • Spring / Kotlin — for backend developers Both tracks ship with 50 hand-crafted concepts and the same Socratic dialogue engine. Switch tracks anytime in Settings. — How it works — You pick one concept (Optionals, SwiftUI State, Kotlin null safety, JPA transactions…) and have a real conversation with the tutor. It probes your understanding, gives analogies, asks you to predict what code does. When you've actually got it, it marks the concept "Mastered" — and only then. No multiple-choice. No copy-paste. No "great job!" filler. Just genuine back-and-forth until the idea clicks. — What's in each track — Swift / iOS (50 concepts) Variables, Optionals, Closures, Protocols, Generics, async/await, SwiftUI state, Concurrency, Macros, and more. Spring / Kotlin (50 concepts) val/var, null safety, data classes, Coroutines, Spring Boot DI, JPA, transactions, REST design, large-scale system patterns, and more. — Features — • 100+ concepts across two tracks (50 per track) • Daily learning rhythm with streaks • Streak Shield — skip a day, your streak survives • Track-scoped study history — revisit any mastered concept and replay your conversations • Mastery tracking that actually means something (not "you saw it once") • Localized for Korean and English • Anonymous by default — no account, no email, just learn • Open privacy practices — see PRIVACY.md in our repo — Who is it for? — iOS developers learning Swift seriously. Backend developers working with Spring/Kotlin. Bootcamp graduates filling conceptual gaps. Self-taught coders who keep getting stuck on the same things. Anyone tired of tutorials they forget by next week. — What's not in CodeStudy — No trackers. No analytics SDKs. No ads. No upselling. Just the tutor. — Built by — A solo developer who got frustrated with how today's coding tools optimize for the wrong thing (giving answers fast). CodeStudy optimizes for what actually matters: long-term retention. Try it. Pick a track. Master your first concept in 5 minutes. The dialogue is the lesson.

Verdict
The clearest difference is in-app purchases: CodeStudy at none against 뿌리깊은 토익단어(어원으로 새기는 영단어)'s 3. CodeStudy also leads on update cadence (every 6 days vs every 3 weeks). 뿌리깊은 토익단어(어원으로 새기는 영단어)'s advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.0). On price and ads there is nothing between them.
