Mobilions builds cross-platform apps that run on iOS and Android from one codebase. Part of our wider mobile app development practice, we pick Flutter or React Native to fit your product, then ship to both stores for far less than two native builds.
Share a few details and our team will reach out to you within 24 hours.
One codebase, both app stores, and the right framework chosen for your product. Design, code, backend and launch handled by one team.
One codebase that ships to both the App Store and Google Play. We build the same feature once instead of twice, which is why cross-platform cuts mobile build cost by 30 to 40 per cent and launch time by up to half against separate native apps.
The framework decision shapes cost, hiring and performance, so we make it with you up front. Flutter app development for pixel-perfect UI and animation, React Native for teams already in JavaScript, and an honest steer toward native when that is genuinely the better call.
A cross-platform app needs a solid server behind it. The same team builds the backend, so authentication, data sync and real-time features work reliably across both platforms from day one.
Cross-platform is the fastest honest route to both stores on one budget, which makes it ideal for MVPs. We ship a working app on a framework that can grow with you, so version two is an extension, not a rewrite.
Smart features built in: on-device inference where it fits, and LLM and generative features through a secure backend, working the same way across iOS and Android.
Frameworks and stores move quickly. The same engineers keep your app current across both platforms at once, which is far cheaper than maintaining two separate native codebases.
Building separate native apps for iOS and Android means paying for everything twice. For the majority of business apps, one cross-platform codebase delivers the same result for far less, which is why Flutter and React Native now power over 80 per cent of cross-platform apps.
Two native apps mean every feature is built, tested and maintained twice. A cross-platform codebase builds it once and ships to both, cutting build cost by 30 to 40 per cent and launch time by up to half, without trading away quality for most products.
We are not tied to one tool. Flutter wins on pixel-perfect UI and animation, React Native wins for teams already in JavaScript, and we choose based on your product and team rather than habit. The reasoning is always shared with you.
We will say so when cross-platform is not the right fit, for example an app built entirely around heavy, platform-specific hardware. Most products do not need that, but we would rather point you to native iOS or Android than sell you the wrong approach.
Five phases, with a tangible output at each one. Working builds on both iOS and Android every two weeks.
You describe the app and its users. Our engineers recommend Flutter or React Native, or native where it genuinely fits, map the features and backend, and plan the path to both stores. The decision comes with reasoning you can challenge.
Interface designs that look right on both iOS and Android, turned into an interactive prototype. You see and feel the app before a line of production code is written.
AI scaffolds components from approved designs in your chosen framework. Engineers own the architecture, the shared logic, the native modules and the backend. A working build for both platforms lands every two weeks.
Tested on real iPhones and Android phones together. Performance, security and accessibility checks, plus a pass against both App Store and Google Play guidelines before submission.
We submit to the App Store and Google Play, handle both reviews and publish. Crash monitoring and analytics are live from launch, and the same team handles updates across both platforms at once.
From AI architecture to cloud deployment, design, engineering and infrastructure are handled by one team. No coordination overhead, and no gaps in quality.
Start Your ProjectA few products that show what one accountable team can ship, built to be genuinely used.
AI-powered fitness coaching app that personalises every workout based on performance data, injury history and recovery signals. Built with Flutter for iOS and Android with adaptive programming, breathwork sessions and multi-mode training timers.
An app that helps parents find kids clothes in seconds. Live stock across every screen on iOS (Swift) and Android (Kotlin), backed by a Laravel admin panel the store team runs without engineers.
Turns the weekly chore argument into a game. Parents set tasks and rewards, kids pick a hero, finish chores and earn cookies they spend in an in-app shop. Built on React Native with Swift, Kotlin and a Laravel backend.
A Flutter-based mobile marketplace where fashion finds a second life. Buyers discover curated listings on a visual feed and message sellers directly; sellers photograph, price and publish items in under two minutes. One app, two sides of the same closet.
Production tools chosen by engineers who use them daily. The framework selection depends on the product.

It was a wonderful experience working with Tushar, Ankit, and their team. They built a great mobile app for me and truly brought my vision to life. What stood out was not just their technical skill but their attitude: always positive, solution-oriented, and incredibly patient. They went above and beyond at every step, finding creative workarounds and staying committed even when things got challenging. Extremely professional and trustworthy. I would absolutely hire them again.
Common questions about cross-platform development, framework selection, timelines and costs.
A cross-platform app in the Netherlands typically costs between EUR 15,000 and EUR 80,000 in 2026, depending on complexity. A simple app or MVP sits around EUR 15,000 to EUR 30,000, while a feature-rich product reaches the upper end. Because one codebase serves both iOS and Android, cross-platform usually costs 30 to 40 per cent less than building two separate native apps. Before any code is written, we hand you a fixed proposal with the scope and price in plain language.
Cross-platform app development means writing one codebase that runs on both iOS and Android, instead of building two separate native apps. The two leading frameworks in 2026 are Flutter and React Native, which together power over 80 per cent of cross-platform apps. The approach cuts cost and launch time sharply, because the same code ships to both stores.
Both are excellent, and the right choice depends on your product and team. Flutter, built on Dart, leads on pixel-perfect UI and animation and holds the larger market share at around 46 per cent. React Native, built on JavaScript, suits teams already working in React and has a vast ecosystem. We recommend the honest fit for your situation rather than a default, and we build both.
Cross-platform typically costs 30 to 40 per cent less than building two separate native apps, and can cut launch time by up to half. Instead of building, testing and maintaining the same feature twice, once in Swift for iOS and once in Kotlin for Android, you build it once and ship to both stores. The saving continues after launch, because updates go to both platforms at the same time.
For the vast majority of apps, yes. Flutter compiles to native code and renders with its own engine, while React Native's New Architecture has closed the old performance gap. Both hold smooth performance for typical business apps, MVPs and content-rich products. Only apps built entirely around heavy, platform-specific hardware genuinely need to go fully native.
Choose cross-platform when budget, speed and a simultaneous iOS-plus-Android launch matter, which is true for most startups, MVPs and business apps in 2026. Choose native when the app is built around deep platform-specific features or needs absolute peak performance. We assess your product honestly and tell you which fits, rather than pushing one answer.
Both. The same Mobilions team builds the cross-platform app and the backend it talks to, whether that is Firebase or a custom Node.js or Python server. Authentication, data sync and real-time features work reliably across iOS and Android from day one, with no separate vendor to blame.
Yes, the Netherlands and the wider EU are home turf for us. Our European base is in Amstelveen, near Amsterdam, so Dutch and EU clients get a local point of contact, apps built to GDPR and AVG standards by default, and invoicing in euros. We also support Dutch payment expectations like iDEAL where relevant.
