As a mobile app development agency, we build high-quality apps for iOS and Android. Our team in Rotterdam works with clients across the Netherlands, from startups to enterprise organisations.
Technologies we use
Our process
A mobile application is the perfect extension of your service or product. As a development agency we guide the entire journey: from technical advice and architecture to development, testing and publication in the app stores.
We build native apps (Swift, Kotlin) and cross-platform apps with Google Flutter. Along the way we apply modern techniques such as push notifications, offline-first architecture and augmented reality.
Want to know what the journey from idea to app store looks like? On our having an app built page we explain the full process step by step.
More about Flutter app development →No surprises, just results. Here is what happens when you contact us.
Let's grab a coffee. Tell us about your idea and we'll explore the possibilities with you straight away.
We translate your idea into a technical plan: which technology fits, what the architecture looks like and what it costs.
Our designers build a clickable prototype. You see the app before a single line of code is written.
We build in short sprints and keep you updated weekly. You see progress, no surprises.
Publication in the App Store and Google Play. After going live we remain available for maintenance and further development.
Android
With a market share of 60% in the Netherlands, Android is the most widely used mobile operating system. Our team develops Android apps in Kotlin and Flutter that perform well on both smartphones and tablets.
We handle a smooth publication to the Google Play Store and advise on App Store Optimisation so your app is discoverable by the right audience.

Get in touch →iOS
For iPhone and iPad apps we work with Swift and Flutter. Our iOS developers have extensive experience with Apple guidelines and ensure a smooth review and publication in the App Store.
We also help set up your App Store Connect environment, including screenshots, descriptions and App Store Optimisation, so your app is easy to find.

FAQ
We build mobile apps with Flutter, Swift and Kotlin. Flutter is our default choice for projects that need both iOS and Android: one codebase, two platforms, with native performance. For projects where deep integration with platform-specific APIs is essential, we choose native Swift (iOS) or Kotlin (Android).
Alongside the app itself, we also build the backend and APIs, typically in Node.js or NestJS on Google Cloud. The choice of technology always depends on your specific requirements, the type of app, the desired functionality and the timeline. We always explain why we recommend a particular technology during the intake meeting.
The cost depends on the complexity, the chosen platform and the number of features. A simple app starts from €10,000. A platform with multiple user roles, a backend and integrations with external systems can quickly reach €30,000 to €60,000 or more.
We work on a fixed day rate and produce a detailed quote per phase, so you always know what you are getting and what it costs. After an intake meeting we give you a realistic estimate based on your specific requirements.
A simple app is typically built in 6 to 10 weeks. A more complex platform with multiple user roles, integrations and extensive design takes 3 to 6 months. The preparation phase, from intake meeting to approved quote, takes 2 to 4 weeks.
We work in two-week sprints. After each sprint you receive a working version to test and provide feedback on. That prevents discovering at the end of the project that something works differently than expected.
Yes. With Flutter we build iOS and Android apps from a single codebase. That saves considerably on costs and timeline compared to two separate native apps. Performance is comparable to native apps: Flutter compiles to native code and does not use a webview.
We publish the app in both the Apple App Store and Google Play Store and guide the entire review process. If you want a purely native app, we build that in Swift for iOS or Kotlin for Android.
Yes. We have extensive experience integrating with systems such as AFAS, Exact, SAP, Salesforce and custom APIs. We also build the backend and APIs ourselves, so you have one point of contact for the entire technical picture.
During the intake meeting we assess which integrations are needed, which APIs are available and whether there are limitations on the side of the existing systems.
After launch we provide monitoring and can handle maintenance. Each quarter we issue an advisory report on recommended maintenance work: framework updates, dependency upgrades, security patches and performance improvements. You decide which to commission. There is no mandatory maintenance contract.
Keep in mind that deferring updates builds technical debt. The source code is entirely yours: you can also continue with another party if you prefer.
