App development costs: How much does app development cost?

Short answer: App development costs at a glance

If you are developing an app, these are realistic corridors for B2B projects in Germany:

• MVP base (Login, profile, 3-5 core functions, simple backend): 20.000-35.000 €
• Business app (multiple roles, push, analytics, integrations): 40.000-80.000 €
• Enterprise/Platform (multilingual, complex processes, payment, scaling): 90.000-150.000 €+

For a quick, rough estimate: App cost calculator.

The final price depends on functionality, platforms (iOS/Android/Web), integrations, design, security and operation. Below are the most important levers.

Price factors: Why app development costs vary

1. Functional scope - the strongest cost driver.
2. Platforms - iOS, Android, possibly web; Cross-platform saves.
3. Backend & API - Data Model, Auth, Roles, Admin.
4. Integrations - ERP, CRM, Payment, Maps, SSO.
5. UX/UI - Prototype, Design System, Accessibility.
6. Security & Compliance - GDPR, audit logs, pen tests.
7. QA - Unit/UI/E2E, device testing.
8. DevOps - CI/CD, monitoring, scaling.
9. Operation - Updates, support, further development.

Example calculations: From MVP to platform

MVP example (8-10 weeks)

• Flutter app (iOS/Android), login, profile, 3 core features
• Backend Micronaut or Spring Boot, PostgreSQL, simple admin view
• Basic analytics and crash reporting

Budget framework: 20.000-35.000 €

Business app example (12-16 weeks)

• Additional roles and permissions, push, offline capability Light
• 2-3 integrations (e.g. Payment, CRM, Maps)
• Advanced design system, automated testing, monitoring

Budget framework: 40.000-80.000 €

Platform Example Enterprise (16-24+ weeks)

• Multilingualism, complex workflows, multi-client capability
• Payment, subscriptions, reporting, data export, comprehensive security
• Kubernetes, horizontal scaling, extended test pyramid

Budget framework: 90.000-150.000 €+

Platform choice: cross-platform vs. native

Cross-platform (Flutter) reduces effort through a code base for iOS and Android. Nativ (Swift/Kotlin) is worthwhile for very hardware-related features or maximum platform conformity.

Backend, data and integrations

A clean backend (e.g. Micronaut/Spring Boot, PostgreSQL, OAuth2/Keycloak) is mandatory. Integrations are often expensive, but save operating costs later.

Design, prototyping and accessibility

Prototype and design system save iterations. WCAG accessibility increases usability and reduces support.

Quality assurance and testing strategy

Solid tests (Unit/UI/E2E) plus device matrix prevent regression errors and reduce maintenance costs.

Running costs and TCO

In addition to the initial development, you should Total Cost of Ownership schedule:

• Hosting/Cloud: 100-1,000 € / month (depending on load)
• Monitoring/Logging: 50-300 € / month
• Maintenance/Updates: 10-20% p. a. of the initial budget

Saving tips without loss of quality

• Focused MVP instead of full expansion.
• Cross platform with Flutter.
• Design System instead of individual screens.
• Standard integrations instead of special solutions.

Conclusion: Plan costs smartly, maximize value

App costs can be planned if the scope, platform choice and architecture are decided wisely. Anyone who starts with a focused MVP, establishes proper quality assurance and collects real user data early on reduces risk and increases ROI. We support you from budgeting to stable operations.
