Cross-Platform Development

One Codebase. Both Platforms. 60% Lower Cost.

Cross-platform apps in Flutter and React Native that feel native on iOS and Android โ€” from a single shared codebase that's half the price and half the timeline of building two native apps.

When Cross-Platform Goes Wrong

Cross-platform done badly gives you the worst of both worlds. Here's what to avoid.

Performance Jank

Poorly optimised cross-platform apps scroll at 30fps, feel laggy on transitions, and get 2-star reviews. Proper widget lifecycle management and render optimization fixes this completely.

Ignoring Platform Idioms

Using the same navigation pattern on both iOS and Android makes the app feel 'off' on both. Platform-aware components are essential for a native feel.

Bridge Bottleneck (React Native)

Heavy JavaScript-to-native bridge calls for animations or gestures cause noticeable lag. Using Reanimated 3 (runs on the native thread) eliminates this.

No Code Sharing Strategy

Ending up with more platform-specific code than shared code defeats the purpose. A feature-first folder structure and dependency injection enforces clean separation.

Security Not Adapted Per Platform

iOS Keychain and Android Keystore handle secure storage differently. A shared 'storage' abstraction that uses the right native API on each platform is non-negotiable.

OTA Update Misuse

Shipping native code changes via OTA (bypassing App Store review) violates Apple's guidelines and risks removal. Only JavaScript/Dart bundle updates are permitted OTA.

Flutter vs React Native โ€” How We Choose

There's no universally better framework. We help you pick based on your team, timeline, and product requirements โ€” then build with the chosen framework to its full potential.

Flutter for pixel-perfect custom UI, animations, and multi-platform (iOS/Android/Web/Desktop)
React Native for TypeScript teams sharing logic with a web app
Both deliver 60fps scrolling and native gesture handling when built correctly
Both support OTA code updates for JavaScript/Dart bundle changes
Flutter's Impeller rendering engine eliminates shader compilation jank
React Native's New Architecture (JSI) eliminates the bridge bottleneck

Cross-Platform Capabilities

60fps Animations

Framer Motion (RN) and custom painters (Flutter) for smooth, native-feeling transitions that don't stutter on mid-range devices.

Biometric Auth

Face ID, Touch ID, and Android Biometric API โ€” abstracted through a platform-aware authentication service.

Offline-First Storage

SQLite/Hive (Flutter) or MMKV/WatermelonDB (React Native) for offline data with background sync when connectivity returns.

OTA Updates

EAS Update (React Native) and Shorebird (Flutter) for instant JavaScript/Dart bundle updates without App Store review.

Push Notifications

FCM for Android, APNs for iOS โ€” handled through a unified notification service with rich media, action buttons, and scheduling.

Native Module Bridge

Custom platform channels (Flutter) and native modules (React Native) for any hardware capability not yet supported by the framework.

Deep Linking

Universal Links (iOS) and App Links (Android) wired to in-app routing โ€” essential for social sharing, marketing campaigns, and referral flows.

In-App Purchases

Apple StoreKit 2 and Google Play Billing abstracted via RevenueCat โ€” subscriptions, consumables, and entitlement management.

Logistics Tracking App โ€” iOS + Android in 10 Weeks with Flutter

A logistics company needed a driver-facing app and a customer-facing tracking app, both for iOS and Android. Building natively would have taken 8+ months. Flutter delivered all four apps โ€” two audiences, two platforms โ€” in 10 weeks.

Challenge

Driver app (iOS + Android) + customer tracking app (iOS + Android) = 4 native builds. Timeline: 10 weeks. Budget: โ‚น50L.

Solution

Flutter with separate app flavors for driver vs customer. Shared data layer (location tracking, order state) with distinct UI and navigation.

Outcome

Delivered both apps from a single Flutter codebase within 10 weeks. Significant cost saving vs building two separate native apps. Driver and customer apps both live with real-time location, ETA, and delivery photo confirmation.
