What does it cost to build an app in Germany?

If you ask five agencies what an app costs, you will get five different numbers, and most of them will not tell you why. The honest answer is that cost comes down to a handful of concrete decisions: how many screens the app needs, whether it talks to a backend, how many platforms it runs on, and how polished it needs to be before launch. Once you know where your idea sits on those questions, the price range gets a lot clearer.

The three tiers of app cost

Most apps fall into one of three rough categories. These are ranges, not quotes, but they hold up across the German market in 2026.

• Simple MVP (8,000 to 25,000 euros). A single core feature, one platform or a simple cross-platform build, no complex backend. Think a booking form, a content app, or a focused utility. This is the right starting point if you want to test an idea before investing more.
• Full-featured app (25,000 to 80,000 euros). Multiple screens, user accounts, a real backend, push notifications, and both iOS and Android from day one. Most startup apps and serious side projects land here.
• Complex product (80,000 euros and up). Payments, real-time features, admin dashboards, integrations with other systems, or strict compliance requirements. This tier is common for fintech, healthtech, and marketplace apps.

What actually drives the price

Two apps that look similar on the surface can cost very different amounts. The real cost drivers are usually invisible until someone points them out:

• Backend complexity. An app that only displays content is far cheaper than one that manages user data, transactions, or real-time updates between users.
• Design from scratch versus a design system. Custom illustrations and animations look great but add weeks. A clean, well-structured design system gets you to launch faster without looking generic.
• Platform count. Building for iOS and Android together with a shared codebase, like React Native, costs far less than building two separate native apps, unless the product genuinely needs native-only features.
• Integrations. Payment providers, calendar sync, third-party APIs, or existing company systems each add development and testing time.
• Compliance. GDPR is a baseline requirement for any app handling EU user data, not an extra. Apps in regulated spaces such as finance or health carry additional review and documentation work.

Freelancer, agency, or in-house team?

A freelancer is usually the cheapest option per hour, but you take on the project management yourself, and a single person is a single point of failure if they get sick or move on. An in-house team is the most expensive and slowest option to set up, and only makes sense once you have enough ongoing work to keep them busy year-round. A small studio sits in between: you get a team with established working habits, without the overhead of hiring and managing people directly. For most founders building a first app, this is the option that balances cost, speed, and reliability best.

The cost nobody budgets for: maintenance

Development is a one-time cost. Maintenance is not. iOS and Android both ship major updates every year, third-party libraries need updating, and app stores periodically change their rules. A well-built app, with clean code and sensible architecture, might need a few hours a month to stay healthy. A rushed one can need a rebuild within two years. When comparing quotes, ask not just what launch costs, but what year two looks like.

How to get an accurate number for your idea

Any number you read online, including the ranges above, is a starting point for a conversation, not a quote. The fastest way to get a real estimate is to describe what the app needs to do in plain language and let someone experienced ask the right follow-up questions. That conversation usually takes less than an hour and costs nothing.
