We use React Native, Flutter, Swift, and Kotlin with Firebase, Supabase, and custom backends for scalable mobile architectures. Our mobile solutions cover push notifications, offline-first functionality, biometric authentication, in-app purchases, real-time synchronization, and app store optimization (ASO) to maximize visibility and downloads.
