An App That Delivers Value For Your Business
More than a mobile screen — an application that moves your organisation forward.
Mobile applications are an indispensable part of the daily lives of your customers and employees. Whether it is a shopping app, a business tool or a customer portal — a well-built app delivers immediate value. It lowers barriers, accelerates processes and strengthens the relationship with your target audience.
We build mobile applications that are not only functional but also pleasant to use. Every app is strategically designed with the user at the centre. Intuitive navigation, fast loading times and reliable offline functionality ensure that your app is used daily — not just after the download.
From consumer apps to complex business applications: we deliver custom solutions that fit your organisation. We choose the technology that best matches your requirements: native Android, native iOS or cross-platform with Flutter.
- Native and cross-platform development for every platform
- Intuitive user design focused on daily use
- Reliable offline functionality and synchronisation
- Push notifications and real-time updates
- Publication in App Store and Google Play Store

Learn moreWhy Invest In a Mobile Application
An app offers opportunities that a website alone cannot deliver.
A mobile application offers unique benefits that a website cannot match. Push notifications give you direct access to your users. Offline functionality ensures your app is always available, even without an internet connection. And integration with camera, GPS, biometric data and other device features opens up possibilities that web-based solutions do not have.
For businesses, an app means a stronger channel to customers. Consumers spend increasing amounts of time in apps rather than browsers. A well-maintained app increases customer engagement, lowers the barrier for repeat purchases and offers a more personal experience than any other interface.
In addition, an internal app increases the efficiency of your employees. Processes that previously ran via email, phone or paper are streamlined into a single application. Fewer errors, faster handling and more overview for everyone.
- Push notifications for direct communication with users
- Offline availability for continuity without internet
- Integration with camera, GPS and device sensors
- Stronger customer engagement and higher retention
- More efficient internal processes for employees
How We Build a Mobile Application
A proven process from strategy to publication — no surprises.
01
Introduction & Analysis
We discuss your objectives, target audience and desired features. We analyse your market and determine the best technical approach.
02
Project Plan
We translate the analysis into a concrete plan with features, timeline and clear deliverables. You know exactly what to expect.
03
UX Design & Prototyping
We design the user flows and visual design. You see and feel how the app works before we write a single line of code.
04
Development
Our development team builds the app using modern technologies. Every feature is tested for reliability and performance.
05
Backend & Integrations
We build the server-side infrastructure and connect your existing systems such as CRM, ERP or databases. API integrations are set up correctly.
06
Testing & Quality Assurance
We test the app thoroughly on different devices, operating systems and network conditions. Bugs are identified and resolved.
07
Publication & Launch
We handle publication in both the Apple App Store and Google Play Store. Including App Store optimisation and all required assets.

Frequently Asked Questions About App Development
Answers to the questions we receive most often.
How long does it take to develop an app?
A standard app is delivered within 8 to 12 weeks. More complex applications with extensive backend systems or multilingual support take 14 to 20 weeks. The exact timeline depends on the number of features and integrations.
What does it cost to have an app developed?
Costs vary depending on complexity. A standard app starts from €10,000. More complex applications with backend systems and integrations start from €25,000. We always provide a custom quote after a no-obligation conversation.
Do I have to choose between Android and iOS?
That depends on your target audience and budget. With Flutter, we can build one app that runs on both Android and iOS, saving costs. If you need specific native functionality, we recommend native development. We help you make the best choice.
What is the difference between native and cross-platform?
Native apps (Android with Kotlin, iOS with Swift) offer the best performance and full access to device functionality. Cross-platform apps (Flutter) run on both operating systems with a single codebase, saving development time and costs. We advise you on the best approach for your situation.
Will my app be published in the App Store and Play Store?
Yes. We handle full publication in both the Apple App Store and Google Play Store. Including App Store optimisation, screenshots, descriptions and all technical requirements.
Can my app be connected to my existing systems?
Absolutely. We build connections with your CRM, ERP, databases and other business systems through API integrations. Whether it is Exact, Twinfield, Salesforce or a custom system — we ensure seamless integration.
