Cross-Platform

Cross-Platform App Development (Flutter / React Native)

One codebase. Two platforms. Zero compromise. We build cross-platform mobile apps with Flutter and React Native that look and feel native on both Android and iOS.

Cross-Platform App Development illustration

Building separate native apps for Android and iOS used to mean double the budget, double the timeline, and double the maintenance headache. Cross-platform frameworks have changed the game entirely. At Fillicore Technologies in Salem, we leverage Flutter and React Native to deliver production-grade mobile applications that share up to 90% of their codebase across platforms — without sacrificing the native feel users expect.

For startups and growing businesses across Tamil Nadu, cross-platform development is the smartest path to market. You get native-quality apps on both platforms, faster iteration cycles, and a single team maintaining one codebase instead of two.

Flutter vs React Native

Both are excellent. The right choice depends on your team, timeline, and technical requirements.

Flutter (Dart)

Google's UI toolkit with its own rendering engine (Skia). Pixel-perfect control over every element, stunning animations at 60fps, and a rich widget library. Ideal for custom UI-heavy apps and startups wanting a unique visual identity.

React Native (JavaScript)

Meta's framework using actual native components. Leverages the massive JavaScript ecosystem, allows code sharing with React web apps, and has a mature community. Perfect for teams with existing JS/React expertise.

Hot Reload & Rapid Iteration

Both frameworks support hot reload — see code changes reflected instantly without losing app state. This dramatically speeds up development and allows real-time UI experimentation during sprint cycles.

Why Cross-Platform Is a Smart Investment

Reduce costs, accelerate delivery, and maintain a single codebase — without compromising quality.

A

Single Codebase, Dual Deployment

Write your business logic once and deploy to both Android and iOS. Up to 90% code sharing means fewer bugs, consistent behavior, and a unified development workflow that saves Salem businesses significant development costs.

B

Native Performance

Modern cross-platform frameworks compile to native ARM code. Flutter's Skia engine and React Native's new architecture (Fabric + TurboModules) deliver performance that's virtually indistinguishable from native apps for most business use cases.

C

Platform-Specific UI When Needed

Cross-platform doesn't mean identical. We implement platform-adaptive widgets that respect iOS Human Interface Guidelines and Material Design conventions, ensuring your app feels native on each platform while sharing core logic.

Cross-Platform Capabilities

Full native access with the efficiency of shared code.

Shared Business Logic

Authentication, API calls, state management, and data models written once and shared across platforms with clean architecture patterns.

Web & Desktop Targets

Flutter supports web, macOS, Windows, and Linux from the same codebase. React Native extends to web via React Native Web — true multi-platform reach.

CI/CD & OTA Updates

Automated build pipelines with Codemagic or Fastlane. Over-the-air updates (CodePush for RN) let you push fixes without app store review cycles.

Cross-Platform Development Process

Efficient, iterative, and transparent from day one.

1

Framework Selection

Evaluate Flutter vs React Native based on your project needs and team skills.

2

Architecture Design

Clean architecture with shared logic layer and platform-specific UI adapters.

3

Sprint Development

Two-week sprints with hot reload demos and continuous integration builds.

4

Device Testing

Testing across 20+ real devices covering Android and iOS fragmentation.

5

Dual Store Launch

Simultaneous Google Play and App Store submission with ASO optimization.

Frequently Asked Questions

Flutter or React Native — which should I choose?

Flutter excels in custom UI and animation-heavy apps with its own rendering engine. React Native is ideal if your team knows JavaScript and you need deep integration with existing web codebases. We recommend Flutter for greenfield projects and React Native for teams with strong JS expertise.

Can cross-platform apps access device features like camera and GPS?

Absolutely. Both Flutter and React Native provide full access to native device features including camera, GPS, Bluetooth, biometrics, push notifications, and file system through platform channels and native modules.

What's the cost difference compared to native development?

Cross-platform development typically costs 30–40% less than building separate native apps for Android and iOS, since you maintain a single codebase. Development time is also reduced by 40–50%, accelerating your time to market.
