02

UI Design

We create wireframes, interactive prototypes and final design — validated with real users.

03

Development

We develop screen by screen, with weekly builds you can test on your own phone.

04

App Store

We prepare assets, optimize listing and launch on App Store and Google Play.

Frequently asked questions

How much does a mobile app cost?

Cost ranges from 5,000 to 40,000+ EUR depending on complexity, number of screens, integrations and platform. After initial analysis, we provide a detailed estimate. Payments in milestone installments.

How long does mobile app development take?

Simple apps take 6-10 weeks, complex ones 12-20 weeks. First results (functional prototype on phone) visible in first 2-3 weeks.

Native or cross-platform app?

Depends on the project. Cross-platform (React Native, Flutter) reduces costs by 30-40% and covers both platforms. Native (Swift/Kotlin) offers maximum performance for apps with specific hardware requirements (camera, sensors, AR).

Do you handle App Store launch?

Yes, we handle the entire process: screenshot preparation, ASO-optimized descriptions, Apple and Google developer account setup, submission and review management. Including subsequent updates.

Can I see progress in real-time?

Yes, you receive weekly builds you can install directly on your phone (via TestFlight for iOS or direct link for Android). Plus live demo at each sprint.

What happens after launch?

You get a 30-day warranty (free bugfixes). After, you can choose a monthly maintenance plan including crash monitoring, bugfixes, OS compatibility updates and new features.

Does the app work offline?

Yes, we can implement offline functionality with automatic sync when connection returns. Ideal for field apps, deliveries or areas with weak signal.

What technologies do you use for mobile?

React Native and Flutter for cross-platform, Swift for native iOS, Kotlin for native Android. Backend: Node.js, Laravel, Firebase. We choose the right technology based on requirements.

Why do you need a mobile app?

Over 70% of online traffic comes from mobile devices. A dedicated mobile app offers clear advantages over a responsive website: push notifications for retention, offline data access, superior native performance and device hardware integration (camera, GPS, sensors). Companies with mobile apps report an average 150% increase in user engagement and significant improvement in customer loyalty.

We build mobile apps using modern technologies like React Native, Flutter, Swift and Kotlin. Every project starts with a discovery phase where we analyze the target audience, define user journeys and prioritize features for an MVP that quickly validates the business idea.

Native vs Cross-Platform App: Which Is the Right Choice?

A native app (Swift for iOS, Kotlin for Android) offers maximum performance and full access to all APIs and hardware capabilities. It's the ideal choice for apps with complex graphic requirements (games, AR/VR), sensor-intensive apps or when absolute performance is critical.

A cross-platform app (React Native or Flutter) is the optimal solution for most business projects: one codebase for both platforms, 30-40% reduced costs, shorter development time and simplified maintenance. Our cross-platform development services include: UI/UX design adapted to each platform, REST and GraphQL API integration, push notifications, biometric authentication, in-app payments, offline mode and full App Store and Google Play launch.
