We architect, develop, and deploy production-grade cross-platform iOS & Android mobile applications. Powered by React Native and Expo SDK, delivering 60 FPS performance, offline reliability, and fast startup velocity.
Every mobile product we craft incorporates rock-solid state management, offline durability, clean architecture, and silky smooth native user interactions.
Single clean TypeScript codebase powering both iOS and Android. Full support for native gestures, Dynamic Island, widgets, and platform-specific capabilities without maintaining two engineering teams.
Sub-millisecond data reads and writes using MMKV, SQLite, and WatermelonDB. Apps function 100% reliably in offline environments, synchronizing effortlessly with background cloud workers.
Production-grade integration of Apple In-App Purchases, Google Play Billing, Stripe mobile elements, localized mobile wallets (e.g. M-Pesa), Google Maps GPS, Camera, and Biometrics.
Complete submission handling for Apple App Store and Google Play Store. Privacy manifests, App Review compliance, TestFlight staging, and automated Over-The-Air (OTA) updates.
Beyond standard app development, we focus on high-difficulty technical problem spaces where generic agencies struggle.
For logistics, field operations & medical workflows
We design resilient local-first data layers with WatermelonDB and SQLite that keep apps functioning at full speed without internet, executing conflict-free merges upon reconnect.

Transparent sprint execution from day 1, with answers to common technical and platform questions.
State machine definitions, local persistence schema, and API contracts before coding.
Within 10 days, an interactive physical device build running core user flows.
Stress-testing memory leaks, network edge cases, and locked 60 FPS performance.
App Store & Play Store approval with EAS CI/CD for instant live Over-The-Air updates.
React Native delivers a native-compiled iOS and Android application from a single unified TypeScript codebase, reducing ongoing maintenance and development costs by 50%. With the modern Hermes engine and React Native New Architecture (Fabric/TurboModules), performance is locked at 60 FPS with direct native thread execution.
Yes, 100%. We handle developer account setup, provisioning profiles, privacy manifests, TestFlight staging, and guide your app through Apple's strict Human Interface Guidelines and App Review compliance until live approval.
For early-stage startups and funded ventures, we typically deliver an initial functional TestFlight prototype within 10 to 14 days. A complete production-ready mobile MVP with backend APIs, authentication, and core business workflows is delivered in 4 to 6 weeks.
We architect applications with local-first databases like MMKV, SQLite, or WatermelonDB. All user interactions read and write instantly to local storage without spinners or network wait times, syncing with cloud backends in the background when connectivity is restored.
Yes. We frequently conduct codebase audits, eliminate memory leaks, upgrade legacy React Native setups to the latest Expo SDK and New Architecture, and optimize slow re-rendering components to achieve silky-smooth 60 FPS interactions.
From new mobile MVPs to 60 FPS codebase refactors, RafayLabs is ready to engineer your product with startup velocity and enterprise reliability.
