One codebase. Two stores. Native performance on both platforms.
React Native with Expo lets us build production iOS and Android apps from a single codebase — without sacrificing the native performance and UX that your users expect. We build mobile apps that ship to both stores in 12–16 weeks, fixed scope, fixed price.
You need a mobile app for iOS and Android. You want native performance without paying for two separate development tracks.
Mobile app development has two dominant failure modes. The first is over-scope: the client wants every web app feature in the mobile app, which triples the timeline and produces a bloated first version that's slow and hard to navigate. The second is under-scope: the "mobile app" is a web view wrapper — technically on the stores but not actually a native experience.
React Native with Expo is the right production choice for most mobile applications because it eliminates the cost of maintaining separate iOS and Android codebases without sacrificing native performance. React Native renders native UI components (UIKit on iOS, Jetpack Compose on Android) — not web views. The visual output is indistinguishable from a native app for standard UI patterns.
The scope discipline for mobile MVP is more important than for web because App Store review takes time (1–3 days per submission) and fixing a critical bug after launch requires a new version submission. Getting the scope right before development starts means the App Store submission is clean.
A production React Native app live on the App Store and Google Play, with push notifications, native auth, and the core feature set that makes mobile the right home for your product.
Native authentication
Clerk's React Native SDK handles social login (Google, Apple — App Store requires Apple Sign-In for apps with social login), email/password, and biometric authentication via the device's FaceID/TouchID. Sessions are stored securely using React Native Keychain.
Push notifications
Expo Push Notification service handles cross-platform delivery. Notification types, scheduling, and segmented delivery are implemented based on the app's specific notification requirements. Deep links from notifications open the relevant in-app screen.
Offline support
For apps used in low-connectivity environments, critical data is cached locally with React Query or SWR. Write operations are queued locally and synced when connectivity is restored.
App Store and Play Store submission
Production builds via EAS Build (Expo Application Services), certificate management, App Store screenshots and metadata, and submission to both stores. The delivery includes live apps on both stores.
Over-the-air updates
Expo Updates for pushing JavaScript bundle updates without App Store review — critical for fast iteration on non-native code changes after launch. Built on React Native, Expo, TypeScript, Clerk, and your backend API.
One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Mobile apps have a defined MVP scope: the features that justify the App Store presence and provide enough value that users install and return. Fixed scope, fixed price applied to that scope — with both App Store submissions included.
Related engagements.
Questions, answered.
Most production apps require a backend for data persistence, auth, and business logic. If you have an existing backend API, the mobile app is a client that calls it. If you don't have a backend, the backend build is scoped as part of the project — typically a REST API or Convex backend.
App Store rejection for guideline violations is handled within the project scope. We review the App Store guidelines relevant to the app's category before submission to minimise rejection risk. If a rejection occurs, the response and resubmission is included.
We use the New Architecture (Fabric renderer, JSI bridge) via Expo SDK 50+ for new projects. The New Architecture provides better performance and is the direction of React Native's future development.
A production mobile app with native auth, push notifications, and core feature set on both stores typically runs $45k–$80k. Offline sync, real-time features, and hardware integration add to the scope. Fixed-price.
