App development for businesses - from simple to complex
As App agency We develop applications for start-ups, medium-sized businesses, public institutions, and companies with complex requirements. Whether it's a digital product catalog, customer portal, sales tool, logistics app, or internal dashboard - we implement custom apps that fit precisely to the industry, business model, and system landscape. We not only focus on technology and design, but also on a well-thought-out app architecture that can grow flexibly.
Typical applications:
01 Apps for internal processes (e.g. field service, warehouse logistics, training)
02 Mobile commerce applications (for stronger online sales)
03 Service Apps (for customer retention & after-sales)
04 B2B Portals & Dashboards (for partners and suppliers)
05 App-based platforms (for communities, events, or learning)
Our goal: Developing apps that create real added value
Holistic thinking. Efficiently implemented.
App development is not a standalone discipline for us, but part of a comprehensive Digital strategyWe accompany our customers from defining goals through conception and design to technical implementation and marketing. We rely on interdisciplinary teams, agile methods, and close coordination with our customers. The result: digital products with substance.

Managing Partner Technology
Our services in the field of app development:
1. Analysis & Strategy
We start with a deep understanding of target audiences, business models, and market conditions. From this, we develop a sustainable strategy - the foundation for every successful app.
2. Concept & Design
We design intuitive interfaces and create compelling user experiences. From wireframes to UX/UI Design up to clickable prototypes.
3. Technical Implementation
Whether native app, cross-platform, or Progressive Web AppWe develop high-performance, secure, and scalable applications - individually tailored to requirements and infrastructure.
4. Backend & Interfaces
Our apps are not isolated solutions. We develop powerful backends and ensure seamless integration into existing systems.
5. Launch & Further Development
After the Go-Live, we support our customers in the long term: with hosting, monitoring, support, and the targeted further development of the app.
What matters in app development:
Clear goal definition and use cases
Target group-oriented User Experience Design

For which platforms are we developing?
Native iOS Apps
Native Android Apps
Cross-platform with Flutter or React Native
Progressive Web Apps (PWA)
Native app or PWA? The right solution for the right use case.
When developing an app, one quickly faces the question: Native app or Progressive Web App (PWA)? Both technologies have clear strengths - and the right path depends on the use case, budget, and goals. Here is an overview of the differences:
The advantages of a native app
High demands on performance and speed
Need for device features (e.g. camera, GPS, Bluetooth)
App Store presence & monetization through in-app purchases
Strong Personalization & Offline Functionality
Long-term software projects with a wide range of features
The advantages of a Progressive Web App (PWA)
Quickly implementable app projects with a small budget
Platform-independent use on all devices.
Simple distribution via URL instead of App Store download
Web-based applications with responsive design
Projects that are intended to evolve gradually.
FAQ - Questions about App Development
What is meant by app development?
App development refers to the entire process of planning, designing, technical implementation, and publishing a mobile application for iOS, Android, or as a platform-independent PWA (Progressive Web App). Depending on the project goal, the Software development development can be done natively, hybrid, or web-based. App development covers all phases - from idea generation and the UX/UI Design from backend programming to testing and the go-live in the App Store.
What types of apps are there?
Basically, three types of apps are distinguished:
Native Apps They are specifically developed for iOS or Android and offer maximum performance as well as access to all device functions.
Cross-platform apps For example, with Flutter or React Native, apps run on multiple operating systems with a shared codebase.
Progressive Web Apps (PWA) Web applications that behave like traditional apps - but run directly in the browser without the need for download.
The choice depends on budget, target audience, functionality, and strategy.
How long does it take to develop a professional app?
The development time varies greatly depending on the complexity, scope of functions, and desired platform.
MVPs (Minimum Viable Products) Can be realized in approximately 3-4 months.
Complex Applications Projects with multiple modules, integrations, and user roles usually require 6-12 months or more.
At W3, we rely on agile project methods that allow for early usable interim results - with maximum flexibility for further developments.
How much does an app cost?
The costs of app development depend on many factors: design effort, number of platforms (iOS, Android, Web), backend complexity, desired features, and interfaces.
As an experienced app agency, we create a transparent, realistically calculated offer after analyzing the requirements - including a schedule, resources, and scalability. This results in app projects with substance - without surprises.
What are the advantages of an app for companies?
A custom-developed app not only strengthens the digital brand presence, but...
... offers new distribution channels
... optimizes internal processes
... improves customer loyalty
... enables direct user communication via push.
... generates data-based insights about user behavior.
In short: A well-thought-out app is a powerful lever for digital transformation and business success - not only for corporations, but also for small and medium-sized enterprises.
How does the collaboration with W3 work in the development of apps?
Holistic, agile, and collaborative. We begin with an intensive discovery phase where goals, use cases, target audiences, and requirements are clarified.
Then follows conception, design, and technical implementation - in clear stages, with a dedicated project management and regular coordination. Even after the Go-Live, we continue to support our customers - with maintenance, further development, and marketing.
Will the App Store release also be taken care of?
Yes - we accompany our customers through the entire App Store process upon request.
Creation of store assets (screenshots, description, keywords, etc.)
Optimization for App Store & Google Play (ASO - App Store Optimization)
Submission, Testing, Review Communication
This ensures that the app is successfully and professionally positioned.
What happens after the launch?
After the Go-Live comes the next release. We take over hosting, monitoring, maintenance, and targeted further development - based on user feedback and market changes. Upon request, we also analyze the app's KPIs and develop strategies for reach, engagement, and monetization.
