The Contrast

Why standard approaches fall short.

The Common Struggle

The Mobile Development Dilemma

Building separate native apps in Swift and Kotlin doubles development costs, fragments your engineering team, and delays time-to-market. Conversely, low-quality hybrid wrappers feel sluggish and alien to mobile users.

The Kangaroo Advantage

Native Quality With Unified Engineering

We engineer cross-platform mobile apps using React Native and Flutter that share up to 90% of business logic while delivering 60 FPS native performance, platform-specific UI conventions, and full hardware access.

FAQ

Frequently asked questions about mobile app development.

Should we build with React Native or Flutter?+

Both are world-class frameworks. We typically recommend React Native if you have an existing web ecosystem, and Flutter if your app requires heavy custom UI animations and graphics. We help you choose the best fit during discovery.

Will you publish the app to the App Store and Google Play?+

Yes. We manage the full submission process including app bundle signing, privacy policy compliance, screenshot generation, and resolving Apple/Google reviewer inquiries.

Can the app function offline?+

Yes. We build offline-first architectures that store data securely on the device and automatically sync changes to the cloud when connectivity returns.

How do you handle ongoing app updates and OS releases?+

We provide maintenance packages that ensure your app remains compatible with every new iOS and Android version, alongside over-the-air (OTA) updates for rapid bug fixes.
