Overview
Building an app for the Korean market means integrating with Kakao SDK, Naver Login, Korean push notification services, and Korea-specific app store requirements. SOPHIA's development team has deep expertise in the Korean mobile ecosystem.
We develop iOS and Android native apps (Swift/Kotlin), Flutter and React Native cross-platform apps, and specialized mobile solutions including game apps (Unity/Unreal) and medical EMR apps. Our bilingual team handles App Store and Google Play submission, including DUNS number registration for corporate developer accounts.

Frequently Asked Questions
Can you integrate KakaoTalk features into my app?
Yes, we integrate Kakao SDK including KakaoTalk login, share, and messaging APIs. We also integrate Naver Login and other Korean social platforms.
Do you handle App Store submission for Korea?
Yes, we manage the entire submission process for both Apple App Store and Google Play, including Korean localization and DUNS number registration.
What's the difference between native and cross-platform?
Native apps (Swift/Kotlin) offer the best performance for each platform. Cross-platform (Flutter/React Native) uses a single codebase for both iOS and Android, reducing cost and development time.
