App development in Vienna
Updated: 2026-11
Vienna is home to international organisations, service companies and a growing tech scene. We build web apps and PWAs for them that are accessible from the start, as the Austrian Accessibility Act has required for many consumer services since June 2025, with EU hosting and work in English or German.
Your region: Vienna
Vienna combines international organisations, financial and insurance companies and many service businesses that serve consumers. Since 28 June 2025 the Austrian Accessibility Act, the national implementation of the European Accessibility Act, has applied to many consumer-facing digital services such as online shops and banking services.
Accessibility built in from the beginning costs far less than a retrofit. We design keyboard operation, contrast, screen reader support and clear error messages into every app. We work remotely from Zug, with invoicing in euros possible.
How we deliver
Accessible by design
WCAG 2.1 AA criteria are part of the acceptance tests for every screen, not a separate audit after launch.
Plain language
Labels, instructions and error messages are written so that all users understand them, which also reduces support requests.
One codebase
The same application serves desktop and mobile users, so accessibility work is done once and applies everywhere.
Why Innopulse
- —Accessibility as a quality floor in every build.
- —EU hosting in Frankfurt.
- —Remote from Zug, invoicing in euros possible.

Accessibility for apps and online shops
Since 28 June 2025, Germany’s BFSG, Austria’s BaFG and the European Accessibility Act have required accessibility for many consumer services, including online shops and apps used to conclude contracts. We test your app or shop against WCAG, fix the issues in the code and draft the required accessibility information.
PWA development: an installable web app instead of a store app
We build Progressive Web Apps on Next.js and Supabase: one codebase for phone and desktop, installable to the home screen, with defined offline behaviour, web push and data held in Zurich or Frankfurt. Scope is set during scoping, after which a fixed price applies.
Developing a customer portal
A customer portal answers your customers’ most common questions before they call: where is my order, where is my invoice, how do I upload a document? We build portals as web apps with strict separation of customer data, ERP or CRM integration and hosting in Switzerland or the EU.

App development in Frankfurt
Frankfurt’s banks, asset managers and fintechs need client portals and internal tools that pass security review and fit DORA’s requirements for ICT providers. We build web apps and PWAs in English with strict tenant separation, EU hosting and the documentation your third-party risk team expects.
App development in Zurich
For international companies in Zurich we build web apps and progressive web apps in English: customer portals, internal tools and mobile-first applications that install from a link. Where a native store app is genuinely required, we say so up front and take on requirements, concept and project leadership instead of overselling.
App development in Zug
Zug is our home. For trading firms, holding companies and technology businesses here we build client portals and internal apps as web apps and PWAs: secure document exchange, approvals, onboarding and dashboards. Hosting in Switzerland, work in English or German, and meetings in person without travel.
AI consulting in Zurich
For companies in Zurich we combine practical AI with governance: assistants that answer from your own documents with citations, AI integrated into CRM, ticketing or Microsoft 365, and an inventory and risk classification that stand up to FINMA guidance and the EU AI Act. Swiss hosting is available where data requires it.

FAQ
Does the Austrian Accessibility Act apply to our app?
It applies to certain consumer products and services, including e-commerce, unless you are a microenterprise. We check applicability for your specific service.
Is accessibility expensive?
Built in from the start it adds little effort. Retrofitting an existing app is considerably more expensive.
Can you audit an existing app for accessibility?
Yes. We test against WCAG 2.1 AA and deliver a prioritised list of fixes.
