App development in Austria for iOS and Android
We build custom apps for iOS and Android: customer apps, internal tools and digital products including the backend, for companies, associations and media across Austria. Our app development team in Linz and Vienna stays with you from concept and UX design to release and maintenance. The ÖFB App reaches millions of views per month, our projects add up to 34.6 million app downloads, and we have successfully completed 40+ projects.
No matter what stage of the project you're in: we deliver results and big moments on the small screen.

What our mobile app development covers
Good apps happen where technology and design meet. That's why product design, iOS, Android and backend work in the same team.
Native apps for iPhone and Android
With Swift and SwiftUI, we build iOS apps that fit seamlessly into the Apple ecosystem, from iPhone and iPad to Apple Watch and Apple TV. With Kotlin and Jetpack Compose, we build Android apps for smartphones, tablets and wearables. Our CTO Philipp Jahoda is the author of the open-source library MPAndroidChart, which has more than 38,000 stars on GitHub.
Web apps, when the browser is enough
Not every application needs to be in the App Store. We build portals, admin interfaces and desktop tools as a web app with Next.js.
App plus backend and admin area
In the ÖFB App, high-performance interfaces deliver results, tables and live tickers in real time, even on match days with heavy load. Just Jobs connects an app and a web portal, from the digital staff request to the confirmed working hours. Hosting runs in the EU or on-premise.
AI features in apps
For us, AI is part of shipped products. The AI Coach in Rotax TRAX gives drivers prioritized tips like "Brake later" after every stint. The 100 Push-Ups app counts reps with machine learning from camera and sensor data. Around the app, we build AI agents that take work off support and admin, such as the support agent for Just Jobs.
Video and streaming in the app
ÖFB TV is the central streaming platform of Austrian football and a core part of the ÖFB App. Since its launch in August 2025, it has logged over 1 million streaming minutes per month. Highlights are cut and subtitled with AI minutes after the final whistle. Learn more about our video and streaming platforms.
Native, cross-platform or web app?
The most important technical decision happens before the first line of code. We build native apps and use Flutter or React Native when a shared approach fits your product. This overview is our starting point in the discovery:
Native app (SwiftUI, Jetpack Compose)
Fits when: Video, live data, camera, sensors or connected devices are at the core
Strengths: Full performance, new OS features from day one
Trade-offs: Two codebases, more effort in development and maintenance
Our recommendation: Consumer apps with large reach and products with hardware, like the ÖFB App or Rotax TRAX
Cross-platform (Flutter, React Native)
Fits when: Both platforms need largely the same features, such as forms, lists, content
Strengths: One codebase, features ship on iOS and Android at the same time
Trade-offs: Device-level features often need extra native code, dependency on the framework
Our recommendation: Business apps and internal tools with a clearly defined scope
Web app (Next.js)
Fits when: The application is mainly used on desktop or without installation
Strengths: One codebase for all devices, updates without store review
Trade-offs: Limited access to device features, push and offline only partly available, no App Store listing
Our recommendation: Portals and admin areas, often alongside the app
Often the answer is a combination: a native app for users, a web app for the team behind it. We decide based on requirements, not preference.
What an app project with us looks like
It starts with a free, non-binding intro call. You don't need a finished specification for it. After that, one fixed team stays with you from the first sketch through to operations.
- Discovery at a fixed price: We clarify goals, user needs, interfaces and priorities and make the technology decision. Result: a solid plan for scope, time and budget before any code is written.
- Design: User flows, screens and design system, based on user interviews where useful, as for the ÖFB App. More on UI/UX design for apps.
- Development in sprints: iOS, Android and backend are built in parallel. After every sprint you see the progress and set the priorities for the next one. Billing runs as a monthly team retainer with costs known in advance.
- Launch: We submit the app to Apple and Google, see it through review and monitor the launch. We migrate existing platforms too, for ÖFB TV with zero downtime.
- Operations and evolution: The same people take care of maintenance, OS updates and new features.
ÖFB App: the digital home of Austrian football
For the ÖFB, we rebuilt the app from scratch, from concept to relaunch. News, live results, tables, videos and livestreams can be tailored to favorite clubs, competitions and players. The app logs several million views per month and more than a hundred thousand active users. See the ÖFB App project
"Ahoi Kapptn! understood the complexity of Austrian football and its operations 100% from the very first hearing."
Simon-Peter Charamza, Head of Digital Development, ÖFB
LAOLA1 App: sports news based on your interests
For LAOLA1, we were responsible for the app concept and the complete technical implementation. Fans choose their sports, teams and competitions, and live data from LAOLA1 and Sportradar arrives in real time. See the LAOLA1 App project
Rotax TRAX Kart Coach: telemetry drivers can work with
For BRP-Rotax, TRAX combines app and device with an AI Coach and a Driver Score. Six years on the market, more than 50,000 km driven by the community, 40 challenges. See the Rotax TRAX project
100 Push-Ups: fitness app with motion detection
For Foxyfitness, Florian Gschwandtner's company: a native app with motion detection and a scalable backend. More than 100,000 active users, over 20 million push-ups tracked, a 4.8 app rating. See the 100 Push-Ups project
"Ahoi Kapptn! thinks ahead, delivers top-level quality, and is the partner that turns good ideas into brilliant products!"
Florian Gschwandtner, Co-Founder, Runtastic, Tractive & Foxyfitness
Mei Marie: native app for Linde
A native iOS and Android app for Linde, from concept to release in both stores. See the Mei Marie project
Just Jobs: platform for flexible work
App and web platform for hospitality, promotion and event staff, built for Gastro Fighters. See the Just Jobs project
"Ahoi Kapptn! guided us through the entire development process. From the idea, through development to implementation."
Benedetto Wagner, CEO & Managing Director, Gastro Fighters
How much does app development cost?
The concept/discovery phase typically costs €7,000–14,000 [PREIS BESTÄTIGEN]. A business app for iOS and Android with a backend typically costs €50,000–150,000 [PREIS BESTÄTIGEN]. Where your project lands depends on features, platforms, interfaces and operations. Our guide to app development costs in Austria explains how the costs add up.
Our locations: Linz and Vienna

FAQ on app development in Austria
It depends on the scope of the first version and the interfaces. The discovery typically takes 2–4 weeks [ZAHL BESTÄTIGEN], and a business app for iOS and Android with a backend typically takes [ZAHL BESTÄTIGEN] months to its first release. You get a reliable timeline at the end of the discovery.
Typically €7,000–14,000 [PREIS BESTÄTIGEN] for the discovery at a fixed price and €50,000–150,000 [PREIS BESTÄTIGEN] for a business app for iOS and Android with a backend. Development is billed as a monthly team retainer with costs known in advance.
Native apps get the most out of the device, for example with video, live data or hardware. Flutter or React Native save effort when both platforms need the same features. We build both and decide with you in the discovery.
[FAKT BESTÄTIGEN: Once paid in full, you receive the exclusive usage rights to the source code developed specifically for you and access to the repository.] We recommend publishing the app under your own developer accounts with Apple and Google. Open-source libraries remain under their own licenses.
The same people who built it. New iOS and Android versions arrive every year, interfaces change, and users ask for new features. We agree on the scope of maintenance and further development together. That's how the ÖFB App later gained Player of the Match voting and a poll tool.
Apple and Google review every new app and every update. Questions often come up over missing privacy information, a login without test access, or in-app payments. We prepare the store listing and test access, submit the app and handle reviewer questions. Plan a few days of buffer for the first release.
Since June 28, 2025, Austria's Accessibility Act (Barrierefreiheitsgesetz, BaFG), the national implementation of the European Accessibility Act, has applied. It covers certain consumer products and services, such as e-commerce, banking services and passenger transport, including their apps. Microenterprises providing services are exempt. We check in the discovery whether your app is affected; this doesn't replace a legal review. Good contrast, scalable text and VoiceOver and TalkBack support help everyone anyway.
