Mobile App Development

We build mobile apps that users actually keep, not delete after two days. One codebase, native experience on iOS and Android, real revenue generation, and a stronger brand in your users' pockets.

What We Offer

01

Cross-Platform Excellence

One codebase, every platform. With React Native and Flutter, we build apps that run flawlessly on both iOS and Android -- at a fraction of the development time and cost. Cross-platform app development can reduce costs by up to 40% compared to native development, while users get the same premium experience on both platforms. One team, one codebase, double the market coverage.

02

Native Performance

When maximum speed and platform-specific polish are non-negotiable, we build with Swift and Kotlin. Graphics-heavy features, sensor integration, or hardware-level access? We handle it natively. Native iOS development (Swift, SwiftUI) and native Android development (Kotlin, Jetpack Compose) deliver the best performance, platform-specific animations, and immediate access to the latest operating system features.

03

Offline-First Architecture

Your app works at full capacity without an internet connection. Data is stored locally and syncs automatically when the network returns -- users never lose a thing. The offline-first approach is especially critical for field workers, logistics applications, and retail POS systems where internet connectivity isn't always guaranteed. We use Realm, SQLite, and WatermelonDB technologies to ensure reliable local data storage.

04

Smart Push Notifications

We don't spam -- we strategize. Personalized, behavior-based push notifications that boost retention and re-engage users who've gone quiet. Our smart push notification system considers user timezone, past interactions, and preferences so the right message arrives at the right time. A well-designed push strategy can increase user return rates by up to 30%.

05

App Store Optimization (ASO)

The best app is worthless if nobody finds it. Our ASO expertise ensures your app ranks at the top of search results in both the App Store and Google Play. App Store Optimization includes keyword research, listing copy optimization, screenshot and preview video creation, and review and rating management. ASO is the most cost-effective form of mobile app marketing.

06

Analytics-Driven Iteration

Data over gut feelings. We track user behavior, identify drop-off points, and continuously refine the experience based on real-world analytics. Using Firebase Analytics, Mixpanel, and custom analytics solutions, we gain precise insights into how users interact with your app, where they get stuck, and which features are most popular. The data-driven approach ensures every development decision is backed by measurable results.

07

UI/UX That Users Love

First impressions are everything. We design interfaces that are intuitive, beautiful, and unmistakably your brand. The goal: 5-star reviews and organic word-of-mouth. Our mobile app UI/UX design process includes wireframes, interactive prototypes, and user testing to ensure the app feels natural from the very first interaction. We deliver pixel-perfect designs created in Figma that follow both Apple and Google design guidelines.

08

Scalable Backend Integration

Robust server-side infrastructure that handles the load from thousands to millions of users. Real-time sync, secure APIs, and reliable data storage -- serious power behind your app. For backend development, we use Firebase, Supabase, or custom Node.js/Go server solutions. Real-time data synchronization happens via WebSocket and GraphQL subscription technologies, ensuring your app always works with up-to-date data.

Frequently Asked Questions

How much does mobile app development cost?

Mobile app development costs depend on the feature complexity and chosen technology. A simpler app typically costs between EUR 3,000-10,000, while a complex app with custom features ranges from EUR 10,000-30,000+. Cross-platform development (React Native, Flutter) can be up to 40% cheaper than building two separate native apps for iOS and Android. Pricing factors include backend infrastructure complexity, third-party integrations, and UI/UX design detail. We provide a free consultation where we discuss your project in detail and deliver an accurate quote.

Should I build for iOS or Android first?

Platform choice depends on your target audience and market strategy. In most European markets, Android holds over 60% market share, while globally, iOS users tend to generate higher revenue through purchases and subscriptions. For most clients, we recommend cross-platform development with React Native or Flutter, because you can reach users on both platforms from a single codebase. If you prefer to start with one platform, we suggest an MVP (Minimum Viable Product) approach on the platform your target audience prefers, then expanding to the other.

What is cross-platform development and is it worth it?

Cross-platform app development means building an app from a single codebase that runs on both iOS and Android. React Native (developed by Meta) and Flutter (developed by Google) are the two most popular cross-platform frameworks. The biggest advantage is cost efficiency: one team develops one codebase, resulting in 40-50% less development time and cost compared to two separate native apps. Performance today is nearly on par with native apps, and global companies like Airbnb, Facebook, and Google use these frameworks. Unless deep platform-specific integration is required, cross-platform development is almost always worth it.

How long does mobile app development take?

An MVP (Minimum Viable Product) mobile app typically takes 2-3 months to develop, while a fully-featured application takes 4-8 months. Development time depends on the app's complexity, number of custom features (payment integration, real-time chat, map integration), backend infrastructure scale, and UI/UX design detail. We work with agile methodology in 2-week sprints, so you get a usable prototype early in development and can track progress continuously.

How does my app get into the App Store and Google Play?

Getting your app into the stores is a multi-step process that we manage end-to-end. For the App Store (iOS), you need an Apple Developer account (annual fee ~$99); for Google Play, a one-time $25 registration fee is required. Both stores review apps before release -- Apple typically takes 1-3 business days, while Google Play is faster, often approving within hours. We handle store listing optimization (ASO), screenshot creation, privacy policy preparation, and store-specific requirement compliance.

Does my app need a backend?

Most modern mobile apps require some form of backend infrastructure for user data storage, authentication, notification management, and business logic execution. For simpler apps, we use Firebase or Supabase BaaS (Backend as a Service) solutions that are quick to deploy and cost-effective. For complex apps, we build custom backends with Node.js, Go, or Python technologies using RESTful or GraphQL APIs. We always design backend architecture to auto-scale as your user base grows.
