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 β 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: β’ Swift / iOS β for app developers β’ Spring / Kotlin β for backend developers Both tracks ship with 50 hand-crafted concepts and the same Socratic dialogue engine. Switch tracks anytime in Settings. β How it works β You pick one concept (Optionals, SwiftUI State, Kotlin null safety, JPA transactionsβ¦) 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" β and only then. No multiple-choice. No copy-paste. No "great job!" filler. Just genuine back-and-forth until the idea clicks. β What's in each track β 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. β Features β β’ 100+ concepts across two tracks (50 per track) β’ Daily learning rhythm with streaks β’ Streak Shield β skip a day, your streak survives β’ Track-scoped study history β revisit any mastered concept and replay your conversations β’ Mastery tracking that actually means something (not "you saw it once") β’ Localized for Korean and English β’ Anonymous by default β no account, no email, just learn β’ Open privacy practices β see PRIVACY.md in our repo β Who is it for? β 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. β What's not in CodeStudy β No trackers. No analytics SDKs. No ads. No upselling. Just the tutor. β Built by β 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 update cadence: CodeStudy at every 6 days against Sunce's every 6 weeks. Sunce's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.
