Cross-platform mobile apps

React Native app development for modern products, customer apps and internal tools.

Q: When is React Native a good choice for my mobile app?

React Native is a good fit when you need to support both iOS and Android, want to reuse React/TypeScript skills and your app does not rely heavily on platform-specific UI or very low-level device features. It works well for SaaS companion apps, customer portals, internal tools and many marketplace and booking flows.

Q: How does React Native compare with Flutter or fully native development?

React Native, Flutter and native each have trade-offs. React Native is strong when you already use React/TypeScript and want closer alignment with your web stack. Flutter offers a very consistent UI layer and strong performance in many cases. Fully native Android/iOS is best when you need deep platform integrations or highly polished platform-specific UI. During discovery we help you decide which option fits your product and team best.

Q: Can you take over an existing React Native app built by another team?

Yes. We often join React Native projects that already exist. We start with a code and dependency review, check how navigation, state management and API integration are handled, then stabilise any critical issues before planning new features, upgrades or refactors.

Q: Which backend technologies do you usually pair with React Native?

Most React Native apps we build talk to backends implemented in Laravel, NestJS, Node.js or similar stacks, using REST or GraphQL APIs. We can integrate with your existing backend if it is stable and well documented, or design and implement a new API layer if needed.

Q: Will my React Native app feel “native” to users?

If React Native is implemented well and follows platform guidelines, the app can feel very close to native for typical business and product use cases. We pay attention to navigation patterns, gestures, typography and performance per platform, and we add platform-specific tweaks where needed instead of forcing a one-size-fits-all UI.

Q: How do you handle performance and offline behaviour in React Native apps?

We focus on efficient API usage, caching, pagination and UI patterns that keep screens responsive. For offline scenarios we design clear rules for when data is cached locally, how sync works and how conflicts are handled. We also monitor app performance and crashes in production so we can address bottlenecks early.

Q: Can React Native access native features like camera, location and push notifications?

Yes. React Native can use many device features via stable open-source libraries or custom native modules. We regularly implement push notifications, deep links, camera and media access, file handling, maps and other SDKs, and when necessary we bridge directly to native Android or iOS code for more specialised behaviour.

Q: How long does it take to build a React Native app MVP?

A focused React Native MVP with well-defined flows can often be delivered in 8–14 weeks after discovery and design, depending on design depth, number of screens, roles and integrations. Larger products with complex workflows or multiple modules will take longer and are usually delivered in phases.

Q: Do you help with App Store and Google Play submissions for React Native apps?

Yes. We prepare builds for iOS and Android, help configure your Apple Developer and Google Play accounts, set up test tracks and manage release builds. We also assist with app metadata, screenshots and release notes so you have a repeatable publishing process.

QalbIT uses React Native when you want one shared codebase for iOS and Android without sacrificing too much on UX or performance. We design mobile experiences that work smoothly across platforms and integrate cleanly with your APIs, auth and analytics.

React Native development overview

React Native development for cross-platform mobile products

React Native can be a strong fit when you want to launch on both iOS and Android with a shared codebase, while staying close to the React ecosystem you already use on the web.

When React Native with QalbIT makes sense

You want to support both iOS and Android without maintaining two completely separate native apps.
Your team already uses React/TypeScript on the web and wants to reuse skills and patterns on mobile.
You are building a SaaS, marketplace or operations app where consistent UX across platforms matters more than deep platform-specific UI.
You need a partner who understands both React and mobile platform constraints – performance, offline behaviour and store guidelines.

Outcomes we typically target with React Native work

A single, maintainable codebase for iOS and Android that your team can understand.
Good enough performance and UX on real-world devices and networks.
Clean integration with your backend, auth, payments and internal systems.
A pragmatic roadmap for when to use shared components vs platform-specific customisations.

If certain features clearly need native implementation (for example heavy graphics or specialised hardware), we can mix React Native with native modules or, where required, propose native Android/iOS for those parts.

What we build with React Native

React Native capabilities across product and internal apps

We use React Native mainly for product-grade apps that benefit from cross-platform reach – not just simple prototypes.

Product and SaaS companion apps

SaaS & platforms

Mobile companion apps for your SaaS or web platforms – account management, dashboards, notifications and key workflows on the go.

Customer-facing mobile apps

Customer apps

Booking, ordering, marketplace or portal apps that run on both iOS and Android with a shared React Native codebase.

Internal and field tools

Internal tools

React Native apps for sales, operations or support teams that need access to core workflows, even while travelling.

Modernisation of hybrid/legacy apps

Modernisation

Replacing older hybrid or webview-based mobile apps with a cleaner React Native architecture backed by stable APIs.
