React Native Apps Shipped to Both Stores
Cross-platform iOS and Android apps built with Expo — one codebase, two stores, production-grade from day one.
Most mobile apps get built twice — once for iOS, once for Android — burning time and budget. With React Native and Expo, I build both from a single codebase without sacrificing native feel or App Store compliance. MassageGo is a live example: a full on-demand service app with real-time booking, push notifications, and Apple Sign-In, shipped through the App Store review process and actively used in production.

Built for organic growth from day one
Single Codebase, Both Platforms
One React Native codebase targets iOS and Android simultaneously. Shared business logic, navigation, and UI components — platform-specific adaptations only where the stores or native APIs actually require them.
Expo EAS Build & Submit Pipeline
Cloud builds via Expo Application Services — no Mac required for Android, no local Xcode dependency for team members. OTA (over-the-air) updates push JS changes to users instantly without an App Store review cycle.
App Store & Play Store Submission
Full submission pipeline including provisioning profiles, code signing, App Store Connect setup, privacy manifest compliance, and handling review feedback. I've shipped through Apple's review process and resolved real rejection cases.
Push Notifications & Real-Time Updates
Expo Push Notification service wired to your backend events. Real-time data sync via Supabase Realtime — booking status changes, messages, and alerts reach the user's device without polling.
Offline Support & Local Storage
Critical flows (drafts, queued actions, cached data) work without a network connection using AsyncStorage or SQLite. Changes sync automatically when connectivity returns.
Auth & Deep Links
Apple Sign-In, Google Sign-In, and email/password auth with Supabase Auth. Universal links and deep links for notification tap-throughs and shared URLs. Payment flows handled on the web layer where needed — keeping apps clear of Apple's IAP restrictions.
Live example
See it in production
On-demand massage booking app for iOS. Built with Expo SDK 54 and React Native, featuring Apple Sign-In, real-time booking notifications, and a provider dashboard. Submitted and approved through App Store review including privacy manifest compliance and account deletion requirements.
How it works
From discovery to indexed
- 01
Scoping — 1 week
Define screens, navigation flows, offline requirements, and third-party integrations (auth, payments, notifications). I map the App Store compliance requirements for your specific app category before a line of code is written.
- 02
Architecture — 1 week
Expo config, EAS build profiles, navigation structure (expo-router), and data layer design. Auth, real-time, and offline sync patterns agreed up front so they don't need to be retrofitted later.
- 03
Build — 4–8 weeks
Full app build: all screens, navigation, auth, API integration, and push notifications. You get TestFlight builds throughout for real-device testing, with daily progress updates.
- 04
Submission & Launch — 1–2 weeks
App Store Connect setup, privacy manifest, screenshots, and metadata. I handle the submission, monitor review status, and resolve any rejection feedback — through to an approved listing on the App Store.
FAQ
Common questions
- Why React Native and Expo instead of Swift or Kotlin?
- For most product apps, a single React Native codebase ships faster and costs less than two native apps — and Expo's tooling (OTA updates, cloud builds, EAS Submit) removes the most painful parts of the mobile dev cycle. Native Swift or Kotlin makes sense when you need deep hardware integration or extreme performance; for booking flows, marketplaces, and service apps, React Native is the better call.
- Can you handle Apple's App Store review process?
- Yes — I've been through it, including a real rejection cycle. Common rejections I've resolved: App Tracking Transparency compliance, Apple Sign-In button requirements, and account deletion flows. I set up the privacy manifest, handle the provisioning and code signing, and stay hands-on until the app is approved.
- Do you build Android too, or just iOS?
- The codebase targets both by default. If you want iOS first and Android later, I structure the project from day one so the Android build requires minimal extra work. EAS Build handles the Android APK/AAB pipeline in the same way it handles iOS.
- How do OTA updates work?
- Expo's EAS Update lets me push JavaScript and asset changes to users' devices without going through App Store review. This covers UI tweaks, bug fixes, and content changes. Updates that touch native code (new permissions, new native modules) still require a full build and store submission.
- What does a React Native app project cost?
- A focused app (auth, core feature set, push notifications) typically falls in the $8,000–$15,000 range for iOS. Full cross-platform (iOS + Android) with a complex booking or marketplace flow is priced higher. Get in touch with your feature list and I'll give you an honest estimate.
