Mobilions builds Flutter apps that run on iOS and Android from a single Dart codebase. Part of our wider mobile app development practice, with near-native performance, one team, and a build that costs less than two separate native apps.
Share a few details and our team will reach out to you within 24 hours.
From a single Dart codebase to apps on iOS, Android, web and desktop, one team handles design, code, backend and store launch.
One Dart codebase that ships to both the App Store and Google Play. The same feature is built once instead of twice, which is why Flutter cuts mobile build time and cost by 40 to 60 per cent against separate native apps.
Flutter compiles Dart ahead of time to native machine code and draws every pixel itself, so animation-heavy and graphics-rich apps, from fitness trackers like the TrainAERO AI fitness app to dashboards, run at a steady 60 to 120 FPS without the workarounds other frameworks need.
A Flutter 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.
On-device and cloud AI built in. TensorFlow Lite for fast, private on-device machine learning, plus LLM features through a secure backend where they add real value.
Flutter is not only for phones. The same codebase can extend to web and desktop, so an internal tool, a companion app or e-commerce development can reach more screens without a second build.
Flutter, Dart and the stores all change. The same engineers keep your app current across both platforms at once, which is far cheaper than maintaining two native codebases.
Two native teams cost twice as much and drift apart over time. For most business apps, one Flutter codebase delivers the same quality on both platforms for far less, and that is why Flutter now leads the cross-platform market.
Building separate iOS and Android apps means every feature is built, tested and maintained twice. Flutter builds it once and ships to both, cutting build and maintenance costs by 40 to 60 per cent without trading away quality on either platform.
Flutter compiles to native machine code and draws its own pixels with Impeller, so it holds 60 to 120 FPS even on animation-heavy screens. For the vast majority of business apps, users cannot tell it from native, and it leads the market for a reason.
We will say so when Flutter is not the right fit, for example, an app built entirely around deep, platform-specific hardware features. Most products do not need that, but we would rather recommend native iOS, Android or React Native app development than sell you the wrong tool.
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 confirm Flutter is the right fit, map the features and the backend, and plan the path to both stores. The plan comes with reasoning you can challenge.
Interface designs that look right on both iOS and Android are turned into an interactive prototype. You see and feel the app before a line of Dart is written.
AI scaffolds Flutter widgets from approved designs. Engineers own the architecture, state management, the Impeller-rendered UI and the backend, as they did for the recu fashion marketplace. A working build for both platforms lands every two weeks.
Tested on real iPhones and Android phones together, the way we shipped the PixiKwik beauty marketplace. 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, as we did for the TrendzFans live streaming app. 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, not because they look good on a list.
From AI architecture to cloud deployment — design, engineering and infrastructure handled by one team. No coordination overhead, no gaps in quality.

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 Flutter development, timelines, costs and how Mobilions works with clients.
A Flutter app in the Netherlands typically costs between EUR 15,000 and EUR 80,000 in 2026, depending on complexity. A simple app or MVP costs 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, Flutter usually costs 40 to 60 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.
Yes, Flutter is typically 40 to 60 per cent cheaper than separate native builds. With native, every feature is built, tested and maintained twice, once for iOS and once for Android. Flutter builds it once from a single Dart codebase and ships to both stores, so you save on build time, QA and ongoing maintenance, without giving up quality on either platform.
Both are excellent in 2026, and the right choice depends on your team and app. Flutter, with Dart and the Impeller engine, has a slight edge for animation-heavy and graphics-rich apps and now leads the cross-platform market at around 46 per cent share. React Native fits teams that already know JavaScript and need to hire quickly. We recommend the honest fit for your product rather than a default.
Most Flutter apps take two to five months to build, depending on complexity. A focused MVP can ship in six to ten weeks, while a larger app with backend and integrations takes longer. Because it is one codebase for both platforms, Flutter is usually faster to a dual launch than native. We work in two-week sprints with a working build you can try on a real device.
For the vast majority of apps, yes. Flutter compiles Dart ahead of time to native machine code and renders with its own Impeller engine, holding a steady 60 to 120 FPS even on animation-heavy screens. Users cannot tell a well-built Flutter app from a native. Only a small set of apps built entirely around deep platform-specific hardware features genuinely need native.
Yes, Flutter supports both on-device and cloud AI in 2026. We use TensorFlow Lite for on-device machine learning, which is fast, private and works offline, and connect to LLMs through a secure backend for generative and natural-language features. AI is built in where it adds real value, not bolted on as a gimmick.
Both. The same Mobilions team builds the Flutter 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.
