Cross-Platform App Development Services for iOS & Android

One codebase, two platforms, zero compromise — we build high-quality cross-platform mobile apps using React Native and Flutter, delivering near-native performance on iOS and Android from a single shared codebase.

Build Once, Ship Everywhere

Cross-platform development has evolved dramatically. With React Native and Flutter, we deliver apps that feel native on both iOS and Android — cutting your development time and cost in half without sacrificing quality.

Not Sure Which Framework Fits Your Project?

This page covers cross-platform development broadly — both React Native and Flutter. If you already know which framework you want, our dedicated pages go deeper into each. If you're still deciding, keep reading — we'll help you figure out which one (or whether native) is the right call for your project.

React Native

Best if you already have a JavaScript/React team or an existing React web app to share code with. Huge ecosystem, mature tooling, and fast iteration.

Flutter

Best for teams wanting a single codebase with the most consistent, pixel-perfect UI across platforms and typically higher raw performance for animation-heavy apps.

See our React Native Development and Flutter Development pages if you already know which one you want — or get in touch and we'll help you decide.

Built for Excellence

Why Choose Cross-Platform with NIMU

We combine deep technical expertise with a focus on performance, security, and long-term reliability.

Cost Efficient

One codebase typically means significantly lower development and maintenance cost than building and maintaining two separate native apps.

Faster Time-to-Market

Ship to both iOS and Android simultaneously instead of running parallel teams.

Native-Like UI

React Native and Flutter render real native components u2014 not web views.

Cross-Platform App Development: Frequently Asked Questions

React Native is great if you have an existing JavaScript team or web app. Flutter delivers higher performance and richer animations. We recommend based on your specific context.
For most business apps — especially those without heavy device-level integration — cross-platform delivers a near-native experience. High-performance games, AR/VR, or apps needing deep OS-level integration may still benefit from native development, which we also offer.
Yes. We assess your existing codebase and migrate incrementally to minimise disruption.
React Native and Flutter both allow platform-specific code when needed — Bluetooth, NFC, Face ID, and other device APIs are all supported.
Cost depends on feature scope, integrations, and design complexity. We scope each project after understanding your requirements and give you a clear estimate before starting.
Yes. Both React Native and Flutter support responsive layouts for tablets, and Flutter in particular can extend the same codebase to web and desktop with minimal extra effort.
Not quite the same. React Native has mature OTA update tooling (e.g. CodePush) for pushing JS/content changes without an app-store review. Flutter's OTA options are more limited since it compiles to native code — most Flutter updates still go through standard app store review, though content and configuration can still be updated remotely.
When built well, React Native and Flutter apps use real native UI components and can feel indistinguishable from native apps to most users. The gap shows up mainly in highly custom, platform-specific interactions — which is exactly what we account for during platform strategy.
