Mobilions builds native Android apps in Kotlin and Jetpack Compose that run smoothly across the huge range of Android devices. Part of our wider mobile app development practice, Google Play is ready and backed by the same team that builds your backend.
Share a few details and our team will reach out to you within 24 hours.
From a first Android app to a polished experience across phones, tablets and foldables, one team handles design, code, backend and Google Play launch.
Native apps in Kotlin with Jetpack Compose, built for modern Android and tuned to run well across the enormous range of devices your users actually own, not just the latest flagship.
The capabilities native Android reaches that a wrapper cannot: biometrics, payments, background services, widgets and deep hardware access, wired in properly for the devices your audience uses.
An Android app is only as good as the server behind it. The same team builds the backend, so data sync, authentication and real-time features work reliably from day one.
On-device and cloud AI built into the app: smart features, natural language and vision, using Android's ML tooling alongside LLMs where they add real value.
Getting onto Google Play cleanly and staying compliant with its policies. We handle the submission, the data-safety form and the listing, so launch is not a guessing game.
Google ships a major Android release every year, and the device range keeps growing. The same engineers keep your app current, compatible and improving across that spread.
Android runs on thousands of devices, from budget phones to foldables, across many OS versions. An app that looks fine on one phone can break on another. Building for that spread is what separates a real Android app from a demo.
Android spans Samsung, Xiaomi, Google Pixel, OnePlus and hundreds more, each with different screens, hardware and OS versions. We test across that range and support older Android releases, so your app works for real users, not just on the developer's device.
Kotlin and Jetpack Compose give full access to Android, biometrics, background services, widgets, and deep hardware. A wrapper fakes these badly. If your product needs any real Android capability, native is the honest route to a smooth result.
Most app problems live at the seam between the app and its server. Because the same team builds both, authentication, data sync and real-time features just work, and there is no vendor to blame when they do not.
Five phases, with a tangible output at each one. Working builds on real devices every two weeks.
You describe the app and its users. Our engineers map the features, the device range to support, the backend behind it and the path to Google Play. The plan comes with reasoning you can challenge.
Interface designs that follow Material Design 3 and adapt across screen sizes are turned into an interactive prototype. You see and feel the app before a line of Kotlin is written.
AI scaffolds Kotlin and Jetpack Compose screens from approved designs. Engineers own the architecture, the device handling and the backend, as they did for the Ludusio coaching marketplace. A working build lands every two weeks for you to install.
Tested on real phones, tablets and foldables across Android versions. Performance, security and accessibility checks, plus a pass against Google Play policies before submission.
We submit, handle the review and publish, as we did for the Banoun shopping app. Crash monitoring and analytics are live from launch, and the same team handles updates and the yearly Android upgrade.
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 on real Android projects.
From AI architecture to cloud deployment — design, engineering and infrastructure handled by one team. No coordination overhead, no gaps in quality.
Start Your ProjectReal feedback from real clients. Here is what businesses say about working with Mobilions on their mobile and web products.
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 Android app development, timelines, costs and how Mobilions works with clients.
An Android app in the Netherlands typically costs between EUR 20,000 and EUR 150,000 in 2026, depending on complexity. A simple app or MVP sits at the lower end, around EUR 20,000 to EUR 40,000, while a feature-rich or enterprise app reaches the upper end and beyond. Android can carry extra testing costs because of the huge device range it must support. Before any code is written, we hand you a fixed proposal with the scope and price in plain language.
Build native Android when the app needs deep hardware access, top performance or platform-specific features, and consider cross-platform when budget and a fast Android-plus-iOS launch matter more. Native Kotlin is the right call for Bluetooth-heavy, sensor-driven or performance-critical apps. For simpler apps that must hit both stores on one budget, Flutter or React Native can cut costs by 30 to 40 per cent. We recommend the honest fit for your product, not a default.
Android runs on thousands of different devices, while iOS runs on a small, controlled set. Android phones, tablets and foldables from Samsung, Xiaomi, Google Pixel and others have different screens, hardware and OS versions, so an app must be tested across that spread and support older Android releases. That wider testing is real work, and it is why a well-built Android app is engineered for fragmentation from the start.
We build native Android apps in Kotlin with Jetpack Compose, Google's current standard, using Java only where an existing codebase requires it. We follow Material Design 3, build in Android Studio, and add Android capabilities like ML Kit, CameraX and biometric APIs as the product needs. The backend is built by the same team in Node.js or Python.
Most Android apps take three to six months to build, depending on complexity. A focused MVP can ship in eight to twelve weeks, while a larger app with backend, payments and device integrations takes longer. We work in two-week sprints, and each one puts a working build on a real device that you can install and try.
Yes, Google Play submission and policy compliance are something we handle as standard. We build against Google Play policies from the start, complete the data safety section, declare permissions correctly, and manage the testing tracks and the listing. You are not left guessing why an app got rejected.
Both. The same Mobilions team builds the Android app and the backend it talks to, so authentication, data sync and real-time features work reliably from day one. There is no separate vendor to blame when the app and the server disagree.
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.
