Does this sound familiar?

Two codebases, double the cost

Maintaining separate iOS and Android apps doubles your development time, maintenance effort, and costs, without adding any value for your users.

Too slow to market

Your competitors ship features in weeks while your development cycle takes months? Time-to-market determines who wins market share.

Users are dropping off

Slow load times, inconsistent UX, or no offline support? Users expect native performance, regardless of the platform they're on.

How we solve it

Our approach in detail

Cross-platform with Flutter

FlutterDartMaterial DesignCupertino

We rely on Google Flutter as our primary app development framework, and for good reason: a single codebase for iOS, Android, web, and desktop, with native performance across the board.

Flutter compiles directly to native ARM code, not a WebView. That means 60fps animations, fast startup times, and a look and feel that feels right at home on every platform.

For you, this translates to up to 40% lower development costs and significantly faster feature releases, because every update only needs to be built once.

Native development: when it counts

SwiftKotliniOSAndroidWatchOS

Sometimes native is the right call. When maximum hardware access is required, Bluetooth Low Energy, NFC, ARKit, HealthKit, or specialized sensors, we develop natively in Swift (iOS) and Kotlin (Android).

Our experience spans fitness tracker integrations, IoT mesh networks, industrial Bluetooth controls, and wearable apps for Apple Watch. We know when Flutter is enough and when native is the better choice.

From MVP to enterprise app

CI/CDTestFlightFirebaseApp StorePlay Store

Whether you're validating an idea or scaling an existing app, we support the full lifecycle:

MVP in 6–8 weeks: We build a working prototype that lets you gather real user feedback, before you commit to a full investment.

Scale-up: Automated CI/CD pipelines, monitoring, A/B testing, and performance optimization for apps with thousands of active users.

Enterprise: Role-based access control, SSO integration, compliance features, and dedicated support agreements.

Your app in 5 steps

Discovery

1–2 Weeks

We analyze your requirements, target audience, and market. Deliverable: specification, wireframes, and technology recommendation.

UX & Design

2–3 Weeks

Our design team creates user flows, wireframes, and a clickable prototype in Figma. Deliverable: agreed UI/UX design, ready for development.

Development

6–12 Weeks

Agile 2-week sprints with regular demos. You always have full visibility into progress. Deliverable: a working app with all features.

Testing & QA

2 Weeks

Automated tests, manual QA, and beta testing with real users via TestFlight/Firebase. Deliverable: a stable, performant app free of critical bugs.

Launch & Support

Ongoing

App Store submission, monitoring, and analytics setup. After launch: maintenance, updates, and continued development. Deliverable: your app, live and in good hands.

Frequently Asked Questions

How much does app development cost?+

Costs depend on scope, complexity, and platform. A simple MVP starts at around €15,000–25,000. A full cross-platform app with backend typically falls between €30,000–80,000. Enterprise apps with complex integrations can exceed that. After a free initial consultation, we provide a transparent quote broken down by phase and effort. No hidden costs.

How long does it take to develop an app?+

We can deliver an MVP (Minimum Viable Product) in 6–8 weeks. A complete app including design, development, and testing typically takes 3–5 months. The exact timeline depends on feature complexity, backend requirements, and feedback cycles. In our kickoff workshop, we define a realistic schedule with clear milestones together.

Flutter or native, which is better for my project?+

Flutter is an excellent fit for 90% of app projects: business apps, e-commerce, social, fitness, dashboards. You save 30–40% in development costs while still getting native performance. We recommend native development when: intensive hardware access is required (AR, BLE mesh, specialized sensors), maximum performance is critical (gaming, video processing), or one platform clearly dominates. Our honest take: we advise technology-agnostically. If native is the better fit, we'll tell you, even though Flutter is our primary tool.

Can you take over or modernize an existing app?+

Yes. We start with a code audit to assess architecture, code quality, and technical debt. Based on that, we recommend either a gradual modernization or, where economically sensible, a rebuild with migration of existing data and features.

How does the collaboration work?+

Transparently and agile. You get a dedicated point of contact, access to our project management tool, and a demo of the current state every two weeks. We work in sprints: you prioritize, we build, you give feedback. No black box, you always know what we're working on and where the budget stands.

Do you offer maintenance and support after launch?+

Absolutely. We offer flexible support models: from a monthly retainer (updates, monitoring, bug fixes) to ongoing development with fixed sprint capacity. 90% of our clients work with us long-term, some for over 6 years.
