Codebases, documentation, and architectures are built for clarity, handover, and long-term evolution — not dependency on vendors.
React Native app development cost is quoted per project and depends on features, native module needs, integrations, and backend complexity. We tailor the scope to your budget — from MVPs to multi-country platforms. Share requirements on a short call and we'll send a written estimate within 48 hours, free, with no obligation.
Most RN apps ship from kickoff to store launch in 8 to 16 weeks. Expo MVPs across iOS and Android: 6–10 weeks; mid-scope apps with custom native modules: 12–14 weeks; enterprise platforms with brownfield native integration: 16–20 weeks.
It depends. React Native wins for JavaScript / TypeScript-first teams, tight native UI adherence, and code sharing with React web. Flutter wins on rendering performance, pixel consistency, and single-codebase breadth across embedded and desktop. We benchmark both before recommending.
Expo is the right default in 2026 — EAS Build, Expo Router, and Expo Updates cover 90% of apps and you can eject to bare workflow later. We start bare only when you already have deep native code or strict binary-size constraints.
The New Architecture is React Native's rewrite of the bridge — Fabric (new renderer), TurboModules (synchronous native calls), and Hermes (JS engine) — delivering faster startup, lower memory, and better concurrency. Every new app we ship runs on it.
Yes. We write Swift and Kotlin TurboModules and Nitro Modules when the JavaScript layer isn't enough — BLE, camera, ML Kit, payment SDKs, and custom hardware. Typed bridges so the RN side stays safe.
Yes. We upgrade React Native apps from 0.60-era up to the current release — with Fabric, Hermes, React 18, and TypeScript migration. A two-week paid audit precedes the fix plan.
Default is Zustand plus TanStack Query — server state separated from client state. Redux Toolkit for larger teams with established Redux patterns. MobX when the client's codebase already uses it.
Yes. RN apps are first-class citizens on both stores. We handle Privacy Manifests, App Tracking Transparency, Data Safety declarations, and Play Integrity / App Attest. First-submission approval rate above 95%.
Yes — within Apple and Google's guidelines for JS-only changes. We use Expo Updates or App Center CodePush with staged rollout, channel routing, and automatic rollback on crash spikes.
OpenAI / Anthropic / Gemini via streaming SSE, typed clients, and guardrails; on-device via react-native-executorch and TensorFlow Lite; native-module bridges to Gemini Nano and Apple Intelligence. Hybrid inference is our default.
You do. Full IP assignment on invoice — RN source, native modules, CI/CD, design tokens, and every plugin built for your project.
