Native apps that
users love to use.
We design and develop native iOS apps in Swift for iPhone and iPad: from concept to App Store launch, with premium UX, flawless performance and scalable architecture built to grow with your business.
Why most iOS apps
fail
UX Not Designed for iOS
Apps that look like packaged web views, ignore Apple's Human Interface Guidelines and fail to leverage native patterns. iOS users have sky-high expectations: if the experience isn't fluid, they uninstall.
Poor Performance and Stability
Crashes, lag, excessive battery drain and slow load times. Without optimised architecture, rigorous testing and proper memory management, the app becomes unusable.
No Post-Launch Strategy
Publishing the app is just the beginning. Without ASO, analytics, push notification strategy, A/B testing and an update roadmap, the app dies within the first 90 days among millions of competitors.
Technologies, frameworks
and iOS expertise
Swift & SwiftUI
100% native development in Swift with SwiftUI for modern, reactive interfaces. MVVM architecture, Combine for reactive programming and Swift Concurrency for high-performance async operations.
iOS UI/UX Design
Pixel-perfect design aligned with Apple's Human Interface Guidelines: native gestures, smooth 60fps animations, Dynamic Type, Dark Mode and adaptive layouts for every device.
Backend & API
Scalable backend architecture with REST API and GraphQL, secure authentication (OAuth 2.0, Sign in with Apple), cloud database and real-time sync for an always up-to-date user experience.
Apple Core Features
Push Notifications (APNs), In-App Purchase, HealthKit, ARKit, CoreML, MapKit, Core Data and CloudKit: we leverage the full Apple ecosystem for native capabilities impossible on the web.
Testing & QA
Unit tests, UI tests, integration tests and performance tests with XCTest. Beta testing via TestFlight, crash reporting with Firebase Crashlytics and performance monitoring with Instruments.
App Store & ASO
App Store submission with listing optimisation (ASO), professional screenshots, App Preview video, review guidelines management and a launch strategy to maximise downloads.
Architecture built
to scale
Every app we build starts from a solid foundation: modular codebase, dependency injection, a separate networking layer and the MVVM pattern for long-term testability and maintainability.
The result: apps that update easily, integrate new APIs without rewriting everything and maintain excellent performance even at millions of users.
Discover our approach Launch is just
the beginning
We monitor downloads, DAU, retention, crash rate and revenue in real time. Every metric drives decisions: which feature to build next, where to optimise onboarding and how to reduce churn.
Continuous ASO, screenshot A/B testing, review management and an update roadmap based on real usage data.

Testing & Launch
Rigorous QA across all target devices, beta testing with TestFlight, performance optimisation and App Store submission with ASO and a go-live strategy.
Grow & Iterate
Analytics monitoring, review management, A/B testing, push notification strategy and an evolution roadmap grounded in real usage data and user feedback.
Questions about
iOS app development?
Why develop natively instead of cross-platform?
Native development in Swift delivers superior performance, full access to all Apple APIs (HealthKit, ARKit, CoreML, Widgets), UX perfectly aligned with iOS user expectations and immediate compatibility with new iOS versions. Hybrid apps trade performance and user experience for lower upfront development costs, but typically cost more in the long run due to maintenance overhead.
How much does it cost to develop an iOS app?
An MVP with 3–5 core screens, authentication and a backend API starts from €15,000–25,000. More complex apps with advanced features (payments, real-time sync, AR, third-party integrations) range from €30,000 to €80,000+. Cost depends on feature complexity, design requirements and backend integrations.
How long does it take to build an iOS app?
An MVP takes 8–12 weeks (2–3 weeks design, 6–8 weeks development, 1–2 weeks testing). Complex apps require 4–6 months. We work in agile sprints with incremental builds on TestFlight, so you can test and provide feedback throughout the entire development process.
Do you handle App Store submission?
Yes, end to end. We manage developer account setup, asset preparation (screenshots, App Preview, ASO-optimised description), submission and the Apple review process. Our first-attempt approval rate is 94%, thanks to our hands-on experience with the App Review Guidelines.
What happens after the app launches?
We offer maintenance and growth plans: crash and performance monitoring, updates for new iOS versions and devices, continuous ASO, review management and incremental feature development driven by analytics. Launch is the beginning, not the end of the project.
Can you also build the Android version?
Yes. We can develop a separate native Android app in Kotlin, or evaluate a Flutter/React Native approach together if budget is a constraint and native performance is not critical. We always recommend launching on one platform first, validating product-market fit, then expanding.
