Mobile application development

Mobile development covers every type of mobile device: smartphones, tablets, and other mobile platforms. We do not choose mobile technologies based on hype, but on what works best for your project, your users, and your budget.

By 2026, cross-platform solutions have matured to a level where they are an excellent choice for most projects. We offer native iOS (Swift), native Android (Kotlin), and cross-platform (Flutter) development. If your goal is rapid market entry on both platforms, Flutter is often the best option. If maximum performance and a platform-specific experience are required, native development may be the better route. There are also special cases. For example, if we build an internal application where the devices are provided by the company (typically Android), native platform tools may be the ideal solution. We help you decide.

What kind of mobile app development can we support?

• Custom B2B or B2C applications – fully tailored to your requirements
• Workflow-supporting back-office mobile applications – digitalising internal processes
• Retail POS, self-service, and ordering applications – improving operational efficiency
• Logistics and fleet management applications – vehicle tracking and field team support
• On-site workforce applications – managing tasks and operations on location
• Fintech applications – investments, personal finance, mobile banking
• E-commerce applications – mobile shops, marketplaces, loyalty apps

Users spend 4–5 hours per day on their phones. A dedicated mobile application allows you to reach them where they spend most of their time.

Why it makes sense to build a mobile app:

• Faster and more convenient usage: Native apps are faster than browser-based websites. Fewer clicks and a smoother checkout process make a significant difference. Mobile users expect speed and intuitive interfaces, which is why UX/UI design plays a key role.
• Push notifications: A direct channel to your customers. Promotions, abandoned cart reminders, or personalised offers reach users instantly without relying on email or social media.
• Digital loyalty cards: The loyalty card is always in the customer’s pocket. Points can be collected automatically, discounts are accessible with one tap, and customer engagement increases.
• Reaching new audiences: A mobile application strengthens both online and offline presence. It reaches customers who prefer browsing and shopping within apps rather than on websites.
• Omnichannel sales: Customers can switch seamlessly between channels. They might browse in the app and purchase in the store, or the other way around. A consistent experience across channels.

The application can start with limited functionality (for example a loyalty app) and later expand with full shop features as downloads and engagement grow.

We choose technologies based on project requirements and user needs rather than trends.

Cross-platform:

• Dart – the programming language behind Flutter
• Flutter – Google’s open-source UI framework for building natively compiled applications from a single codebase

Tools and libraries include Bloc, Riverpod, Dio, Retrofit, Hive, GoRouter, Stripe, Firebase Cloud Messaging, Geolocator, Crashlytics, and Flutter DevTools.

iOS development: Swift, UIKit, SwiftUI, Storyboards, XCode, CocoaPods, RxSwift

Android development: Kotlin, Android Studio, Android SDK, Jetpack Compose, Material Design

Backend and integrations: Firebase, Supabase, REST APIs, GraphQL, push notification systems, and payment integrations. If required, we develop fully custom backend and admin systems. Lightweight backend-as-a-service solutions such as Firebase or Supabase are also used when appropriate. If an existing system already has an API, we integrate with it.

❓ What is a mobile application?
A mobile application is not the same as a mobile-optimised website. Mobile apps are built for Android or iOS and offer features such as push notifications, camera access, GPS, offline functionality, and native performance.

⚖️ How much does it cost to build a mobile app?
Costs typically range from a few million to tens of millions of forints depending on specification, complexity, platform choice, and integrations. After analysing the specification, we provide an accurate estimate.

⚙️ iOS or Android – which platform should you choose?
The answer depends on your target audience. Android users are more numerous, while iOS users statistically spend more on in-app purchases. If you want to launch on both platforms, Flutter provides a cost-efficient cross-platform solution.

⚡ How long does mobile app development take?
Developing a custom mobile application usually takes 3–5 months. The exact timeline depends on complexity, integrations, number of platforms, and the level of specification detail.

⚠️ What are push notifications and why are they important?
Push notifications allow you to reach users in real time with promotions, order updates, reminders, or personalised offers. They improve engagement and support targeted marketing.

➕ Why build a loyalty app?
A digital loyalty card is always available on the customer’s phone. It enables personalised offers, birthday rewards, and special promotions. Loyalty apps are often the first step in building a broader e-commerce ecosystem.

 ✅ Which mobile technology should you choose?
The right technology depends on the project requirements. Native development typically uses Swift for iOS and Kotlin for Android. Flutter is a strong cross-platform alternative that reduces development time and cost.

⚓ Who owns the mobile application after development?
After delivery, the copyright and source code are transferred to the client. Ownership of the application belongs to you.
