iOS users expect the best. We build iPhone and iPad apps that meet those expectations — with sleek design, fluid animations and performance worthy of Apple.
Building an iPhone App That Stands Out
Native quality for the platform where users are most loyal.
iOS users are the most engaged and highest-spending app users in the world. They expect quality, speed and a design that seamlessly fits the Apple ecosystem. An iPhone app that meets these standards gets opened more often, recommended more frequently and used more for purchases.
We build native iOS applications with Swift and SwiftUI — the technologies Apple itself recommends. That means the best performance, the smoothest animations and full access to all iPhone and iPad capabilities. From Face ID and Apple Pay to HealthKit and Core Location — your app can do everything the Apple platform offers.
Whether it is a consumer app, a business tool or a customer portal — we deliver an iOS app that matches your ambition and the quality your users expect.
- Native development with Swift and SwiftUI
- Full integration with the Apple ecosystem
- Fluid animations and premium user experience
- Support for Apple Pay, Face ID and Touch ID
- Publication in the Apple App Store including optimisation
What Sets a Great iOS Application Apart
The elements that make your iPhone app stand out from the competition.
An excellent iOS app follows Apple's guidelines without being boring. Human Interface Guidelines form the basis for an intuitive user experience, but within those boundaries there is room for a unique identity. We make sure your app looks and feels like a first-class Apple product while your brand remains clearly recognisable.
Performance is just as important as design on iOS. Apple users do not tolerate slow apps or long loading times. We optimise every app for speed, efficient memory usage and minimal battery drain. An app that runs smoothly on both the latest iPhone and older models increases your reach and satisfaction.
In addition, reliability is essential. iOS users expect an app to always work, even offline. We build robust applications with smart caching, background synchronisation and error handling that prevents problems before users notice them.
- Design according to Apple Human Interface Guidelines
- Optimised for all iPhone and iPad models
- Smart offline functionality and data synchronisation
- Minimal battery drain through efficient memory usage
- Support for Dark Mode and dynamic type

Frequently Asked Questions About iPhone App Development
Answers to the questions we receive most often.
How long does it take to develop an iPhone app?
A standard iPhone app is delivered within 8 to 12 weeks. More complex applications with extensive backend systems or multilingual support take 14 to 20 weeks. The exact timeline depends on the number of features and integrations.
What does it cost to have an iPhone app developed?
An iPhone app starts from €12,000. This includes design, native development, backend connections and App Store publication. We always provide a custom quote after a no-obligation conversation.
Why native development and not cross-platform?
Native development with Swift offers the best performance, smoothest animations and full access to iPhone functionality. If your app also needs to run on Android, we sometimes recommend Flutter. We help you make the best choice based on your goals and budget.
Will my app also work on iPad?
Yes. We build iOS apps that automatically scale on iPad. If desired, we can add iPad-specific features such as Split View, Slide Over and a custom interface for the larger screen.
Will my app be published in the Apple App Store?
Yes. We handle full publication in the Apple App Store. Including App Store optimisation, screenshots, descriptions, privacy policy and all technical requirements Apple demands.
Can my iPhone app be connected to my existing systems?
Absolutely. We build connections with your CRM, ERP, databases and other business systems through API integrations. Whether it is Exact, Twinfield, Salesforce or a custom system — we ensure seamless integration.
