React Native Mobile App Development
Cross-platform mobile applications for iOS and Android with a single React Native codebase. Native performance, AI features, biometric authentication, in-app payments, offline-first sync.
About this service
We use React Native to deliver applications that look and feel native on iOS and Android, but are built once. We reduce development time by 40-60% compared to pure native and lower maintenance costs, with no performance compromises — because we use native modules where JavaScript isn't enough.
We integrate the entire mobile ecosystem: smart push notifications via Firebase Cloud Messaging, biometric authentication (Face ID, Touch ID), in-app payments (App Store, Google Play, Stripe), geolocation, camera, offline sync with Realm or WatermelonDB. Plus native AI features: conversational assistants, visual recognition, real-time translation.

Frequently asked questions
React Native or native (Swift/Kotlin)?
For 90% of applications, React Native offers native performance at 40-60% lower cost. Pure native is only worth it for extreme cases: graphically intensive games, advanced AR/VR or access to new OS APIs not yet available in RN.
How long does mobile app development take?
MVP with essential features: 8-12 weeks. Complete app with complex integrations (payments, AI, offline sync): 4-6 months. We work in 2-week sprints with regular Testflight/Internal Track builds.
Will the app be published in App Store and Google Play?
Yes. We handle the entire publishing process: developer account, screenshots, ASO (App Store Optimization), descriptions in multiple languages, submission, review responses. Typically the first build is live within 1-2 weeks of completion.
How do you manage app updates?
We use Expo OTA Updates or CodePush for instant JavaScript updates (without App Store review). For new features that require native code, we release major versions through App Store/Play Store. Sentry for crash monitoring, AppsFlyer for analytics.
