App development: test your idea in weeks
You have an app idea but don't know whether it will work? We build your mobile app, web app or desktop application as an MVP (Minimum Viable Product) first, in 4 to 8 weeks, test it with real users and then develop it into a production-ready version. With an experienced team from Austria that develops with the help of AI, saving you time and money.
- 80+ projects
- 5.0 on Google
- EU & GDPR first
- Initial consultation directly with the Managing Director – free & non-binding
Where are you with your app idea right now?
Whether the idea is still sketched on a napkin or the concept is already finished, we meet you where you are and get your app to real users in weeks.
How much does it cost to have an app developed?
An honest answer: it depends on the scope. Four things determine the effort: the feature set, the platforms (iOS, Android, web), the integrations with existing systems and the standards for design and user experience.
That is why we don't quote a flat price, but give you a transparent cost range before every step. The first stage is deliberately small: an MVP with the features real users need. You invest step by step and decide after each step whether to continue.
How we keep costs down
- MVP scope instead of the full build
Together we cut everything that isn't needed for the first test. What users really want comes in the next stage.
- One codebase for iOS, Android and web
With React Native and modern web technologies, the app is built once and runs on all platforms instead of being developed three times.
- AI-assisted development
Our wunderbots take over routine work in code, tests and documentation. More for the same budget, faster to market.
- Factor in funding
Many app and digitalisation projects qualify for grants, in Austria for example through KMU.DIGITAL, the Austrian funding programme for SMEs. We run an initial funding check with you.
From app idea to finished app
No black-box project and no months without results. Every step has a clear outcome, and you decide after each step whether to continue.

Expansion, launch & operation
We develop the app into a production-ready version, publish it on the App Store, Google Play or the web and, if you wish, remain your technology partner for maintenance and further development.
AI writes code. We build software.
Thanks to wunderOS and our wunderFactory.
AI has opened up programming to everyone: anyone can put a prototype together today. Whether it turns into software that holds up in day-to-day operation is decided afterwards – in architecture, security, testing and maintenance over the years. That is exactly where prompting and real expertise part ways.
That is why we built our own operating system: wunderOS runs our company from sales to development. At its heart is the wunderFactory, where our AI agents, the wunderBots, build to the architecture rules, standards and tests from 20 years of software development – led by experienced software architects.
The result is software built noticeably faster and more affordably – in the quality you hire us for. We are AI experts and use that to get the best out of your project.
What you get out of it:
- More software for the same budget
The wunderBots handle the routine work. You pay for architecture, decisions and results – not for legwork.
- Live in weeks, not months
From the workshop to the first usable version, with changes after that in days. You see early on what works.
- Quality is built in, not bolted on
Tests, reviews and security checks run automatically in the wunderFactory with every change – not just when there is time.
- Architects, not prompters
The AI executes, we decide: data model, interfaces, operations. That way your software stays maintainable and extensible five years from now.
Bottom line: Bespoke software on terms that make sense for SMEs too – built with AI, with software architects accountable for it.
AI-generated.
Thank you very much!
I will get back to you as soon as possible!

Frequently asked questions about app development
Your question isn't listed? We will answer it directly with the Managing Director in the free initial consultation.
How much does it cost to have an app developed?
It depends on the feature set, the platforms (iOS, Android, web), the integrations and the design standards, which is why wunderwerk doesn't quote a flat price. You receive a transparent cost range before every step and start with a deliberately small MVP, so you safeguard your investment step by step. You can get an initial estimate for your project via the cost calculation or in the free initial consultation.
What is an MVP (Minimum Viable Product)?
An MVP is the first version of an app with only the features real users need to experience its core benefit. Instead of spending months building everything, you test with a manageable budget whether users adopt the product, and only then invest in expanding it. wunderwerk develops MVPs as mobile apps, web apps or desktop applications, usually in 4 to 8 weeks.
I have an app idea. How do I make it happen?
Ideally in three steps: sharpen the idea and target group, build a clickable prototype and test it on the market with an MVP. wunderwerk supports you from the very first conversation: in the initial consultation we give the idea an honest review, within a few days a clickable prototype takes shape, and within 4 to 8 weeks an MVP for your first users. You need neither technical knowledge nor a finished concept.
How long does it take to have an app developed?
At wunderwerk, a clickable prototype is usually ready within a few days, and an MVP with the core features after 4 to 8 weeks. The production-ready version with all features, integrations and store publication takes three to six months, depending on scope. You see progress every week and receive test versions continuously.
Native app, web app or both? iOS and Android?
For most projects, wunderwerk recommends one React Native codebase for iOS and Android, complemented by a web app if users also need the application on their computer. It feels native but costs considerably less than two separate apps. A pure web app is enough if you need neither a store presence nor deep device features. We clarify which option suits your target group in the initial consultation.
Can you build AI features into the app?
Yes. wunderwerk builds language models, image and document recognition into apps from the start, for example chat with your own data, automatic analysis of photos and receipts, or text suggestions. The models run GDPR-compliant with hosting in the EU, or on-premise if you prefer. Find out more on our AI consulting for businesses page.
We already have a prototype built with Lovable, Cursor or a freelancer. Can you take it over?
Yes, after a paid technical analysis. wunderwerk reviews the code, architecture, security and rights to the source code and shows whether the prototype can be developed into a production-ready app or whether a rebuild is more economical. We see a quickly built prototype as a legitimate first step, not a mistake.
Who owns the app's source code?
You do. wunderwerk develops with open, widely used technologies such as TypeScript, React, React Native and Next.js and documents the software clearly. You get access to the code and the store accounts are in your name, so you stay independent of individual developers and of us.
How does publication on the App Store and Google Play work?
wunderwerk takes care of the submission, the store listings with texts and screenshots, the review communication with Apple and Google, and updates. We set up the developer accounts in your name. With TestFlight and internal test groups, you get a version on your phone every week while the app is still in development.
Is there funding for app development?
Yes, many app and digitalisation projects qualify for grants, depending on country, region, company size and project. In Austria, for example, KMU.DIGITAL funds consulting and implementation. wunderwerk runs an initial funding check with you and shows which options are available for your project.
Do you continue to support the app after launch?
Yes. wunderwerk supports you from the idea to ongoing operation, with hosting in the EU, monitoring, maintenance, updates for new iOS and Android versions and further development with new features. We have been looking after many of our clients for more than ten years.
