Mobile App Development for your business.

When your team and clients need to access business systems from the field, from meetings, or from home - a mobile app makes it possible.

We build business mobile apps that extend your existing systems to iOS and Android - not consumer apps, but tools that drive productivity.

Sound familiar?

When a mobile solution could unlock real value for your business.

Field teams work offline

Sales reps, technicians or inspectors collect data on paper or in personal apps. Information reaches the office hours or days later.

Clients expect mobile access

Your customers want to check orders, make appointments or access documents from their phone - and your system doesn't support it.

Desktop-only systems limit productivity

Your business tools only work in the office. Team members can't access critical information when they need it most.

Consumer apps don't fit business needs

WhatsApp for client communication, Google Sheets for data - workarounds that create security and data management risks.

What does mobile app development mean in practice?

We build mobile applications that extend your business capabilities to iOS and Android - integrated with your backend systems.

Native and cross-platform options

React Native, Flutter, Swift, Kotlin - we choose the technology that best fits your requirements, timeline and budget.

Backend integration included

Your mobile app connects directly to your existing systems. Real-time data sync, no manual imports.

Offline-capable when needed

For field workers and environments with poor connectivity, we build apps that work offline and sync when connection is available.

App Store publication handled

We manage the entire App Store and Google Play publication process including compliance, screenshots and metadata.

How does mobile app development work?

Step 01

Requirements and UX design

We define the feature set, create user flows and design the mobile interface. You see and approve the design before development starts.

Step 02

Platform and tech selection

We recommend the best approach: native iOS/Android, cross-platform (React Native/Flutter) or PWA - based on your needs and budget.

Step 03

Iterative development

We build in sprints with regular TestFlight/beta builds so you can test on real devices throughout development.

Step 04

Backend integration

We connect the app to your business systems - API development, data sync and authentication.

Step 05

Testing and QA

Device testing, performance optimization, accessibility and security testing across iOS and Android.

Step 06

Publication and handover

We handle App Store and Google Play submission, train your team and provide post-launch support.

FAQ.

Cross-platform (React Native, Flutter) covers most business use cases at lower cost. Native development (Swift, Kotlin) makes sense for hardware-intensive apps or when you need the absolute best performance. We'll recommend the right approach for your project.

A focused app with core functionality typically starts from €20,000-35,000. Complex apps with backend integration, offline mode and multiple user roles can be more. We provide a detailed quote after the requirements phase.

An MVP (minimum viable product) typically takes 2-3 months. A full-featured app takes 3-6 months. We recommend launching with core features first, then iterating based on user feedback.

Yes. We manage the entire submission process for both App Store and Google Play, including compliance, screenshots, descriptions and the review process.

We provide ongoing support packages including OS update compatibility, bug fixes, performance monitoring and new feature development.
