React Native apps with proven native-class performance on iOS and Android. App Store and Play Store release support included.
React Native lets you ship native-performance iOS and Android apps from a single codebase. It powers apps with millions of users across every industry. At Kritm we have deep practice with Hermes JS engine, the New Architecture (Fabric / TurboModules), native module integration, OTA updates (Expo EAS / CodePush) and App Store / Play Console release pipelines. When we ship a mobile product end-to-end with you, offline-first behavior and push notification plumbing are wired in by default.
From MVPs to enterprise-grade apps.
Native-feeling apps designed from scratch. Navigation, state management, API integration and store release all included.
Migrate older RN versions to the New Architecture, fix library compatibility, harden performance.
Swift/Kotlin bridges for Bluetooth, camera, maps or any device API the JS layer can't reach.
FCM/APNS push, Amplitude / Firebase analytics, universal link setup — end-to-end configuration.
Tools we use in production.
Incremental approach from MVP to production.
Target users, core flows and platform priority. App Store guidelines are accounted for from day one.
UI/UX following iOS and Android native patterns. Interactive prototype in Figma.
Two-week sprints, internal TestFlight and Play Console builds. Testable app at the end of each sprint.
E2E tests with Detox / Maestro, real device farm, accessibility audit.
App Store Review prep, Play Console release tracks, OTA update pipeline and crash monitoring.
Mobile MVP from $10,000, production-grade React Native app from $18,000.
Top questions about React Native.
Modern React Native (Hermes + New Architecture) matches native performance for most app categories. We only recommend native for very GPU-heavy or AR/VR scenarios.
Yes — typical code share in our projects is 85-95%. We use React Native's Platform APIs for platform-specific behavior, and share the rest.
Yes. We start with a 1-2 week feasibility analysis and a cost comparison against existing features. We then propose either incremental brownfield migration or a full rewrite.
Yes. Certificates, store listing, review prep and release roll-out are all on us. We use your developer accounts if you have them, or help you set them up.
With Expo EAS Update or CodePush we can push JS bundle updates straight to live users without a store review. Ideal for bug fixes and small improvements.
Often shipped alongside React Native projects.
