iOS App Development That Adapts to Your Business

Developing an iOS app is an exciting process that usually takes three to five months. Smaller projects can be completed faster, while larger ones may require more time. The development process includes the following phases:

• Planning (1–2 weeks): We refine your idea and develop a clear concept with all the requirements for design, performance, functionality, and quality.
• Design & Prototyping (3–4 weeks): Based on an initial prototype that visualizes the look and feel of the application, you can experience your iOS app early on. This phase allows for individual adjustments.
• Technical iOS Development (6–12 weeks): The functions and app design for iOS come together in the development environment. Your app takes shape and gets closer to the desired final product.
• Quality Assurance (3 to 6 weeks): After app programming, careful iOS mobile app testing follows to ensure everything works smoothly later.
• App Publication: Finally, we accompany the go-live in the App Store (store release). Your app is ready for users.

We develop iOS apps for all common Apple devices, including iPhone, iPad, Apple Watch, MacBooks, and Apple TV. Thanks to our technological approach, we can ensure that your application runs stably on all devices that Apple regularly supports. We also develop web applications.

Yes, absolutely. Our designers and developers work according to Apple's iOS App Design Guidelines. These guidelines define how apps should be designed and operated, from navigation and buttons to gestures, typography, and spacing.

You can trust that your app will fit seamlessly into the Apple ecosystem, be intuitive to use, and be easily approved by Apple for the App Store.

We offer comprehensive support during the development process, especially in cross-platform app development for Android and iOS, for high-quality and cost-effective solutions.

We guide you through every phase of iOS development, from the idea to the finished app in the App Store. As your full-service partner, we ensure that design, technology, and quality work together optimally and that your project progresses reliably. Our services range from developing warehouse logistics apps to integrating with existing teams to overcome bottlenecks, to project management and consulting.

With our full service for iOS apps, you get a solution that not only convinces technically but also delights your target audience and you as the client.

In iOS app development, we rely on the latest technologies and combine them with many years of experience. Classic programming languages like Swift and Objective-C are as much a part of our repertoire as C# iOS apps, which we develop using .NET MAUI (formerly Xamarin).

This Microsoft technology allows us to program apps for both iOS and Android simultaneously, without having to write separate code for each operating system. This saves development time, reduces costs, and ensures that your app runs smoothly on all devices.

For companies that want to have an iOS app programmed, our expertise offers strong advantages:

• Flexibility: We develop both native solutions and cross-platform apps.
• Efficiency: With Visual Studio or a professional iOS development environment (Xcode), we program apps that work optimally on iPhone, iPad, and more (iOS, iPadOS, macOS, tvOS, watchOS apps).
• Quality: Thanks to iOS mobile app testing and the official iOS App Design Guidelines, we ensure that your app is technically stable and meets the typical iOS app UI design for a compelling user experience.

Whether it's app design for iPhone, the integration of map solutions like OpenStreetMap iOS, or complex business applications, we develop custom solutions for your target audience.

To ensure your app works reliably, we use a structured iOS mobile app testing process. This means we test your application on different devices, operating system versions, and under real-world conditions for factors such as:

• Performance
• Usability
• Security
• Interfaces

Errors or weaknesses are thus detected and eliminated early – before your app goes to the App Store.

iOS app development offers businesses clear advantages over a classic website, especially if you want to reach your customers regularly and directly.

• Optimized App Design for iOS: We develop apps that are tailored to the iPhone and iPad for a smooth, intuitive user experience.
• Access to Device Functions: With an app, your target audience can access device functions like the camera, GPS, push notifications, microphone, or even map services like OpenStreetMap iOS or Google Maps Xamarin iOS. This is only possible to a limited extent in a browser.
• Individual User Experiences: Through personalization, content can be tailored specifically to the needs of the users.
• Faster Access: iOS apps launch directly from the home screen, without going through the browser.
• Higher Performance: Apps are usually more stable, faster, and offer better handling than websites.
• New Business Opportunities: You can tap into additional revenue potential through in-app purchases, subscriptions, or advertising.

With custom app programming for iOS, you get a tool that is technically powerful and builds long-term loyalty with your target audience.

Yes, absolutely. Many companies face the challenge of bringing older iOS apps up to date technically and visually. We handle both the modernization of existing apps and the integration of new functions.

In doing so, we pay attention to current security standards, performance, and a modern design. This way, your app remains future-proof and attractive in the long term.

At Cayas, you will receive a transparent offer without hidden costs. Our goal is for you to have planning security from the very beginning – both in terms of budget and time.

The cost depends heavily on the scope of functions, the desired interfaces, the design, and the planned further development. A simple app is cheaper than a complex business solution with many features.

We have developed a variety of cross-platform apps that cover different industries and use cases:

• Warehouse logistics apps: Optimize internal processes and increase efficiency.
• Driver apps: Support delivery services with safe and precise navigation (including with OpenStreetMap iOS or Google Maps integration via Xamarin iOS).
• Voice command integration: Control functions via voice input for more user-friendliness.
• Field service apps: For order management, reporting and mobile process support.
• Customer portals & service apps: Digital interfaces to customers, orders or support.
• Maintenance and technician apps: For smart process control directly on site.
• Marketing and product apps: For strong customer loyalty and brands to experience.

Thanks to our experience in app development for iOS, we combine modern app design for iPhones with technical excellence in app programming. In doing so, we adhere to the iOS App Design Guidelines and rely on a proven iOS development environment with testing and quality assurance.

Yes. We always implement cross-platform projects such as app development for iOS and Android efficiently. Our customers benefit from shorter development times and a high reusability of code.

With modern frameworks such as .NET MAUI, we can develop applications in such a way that they run on iOS and Android equally. This means: only one common program code for an app that works smoothly on both platforms.

Cross-platform apps for iOS and Android save time, money and ensure that you reach your target group regardless of the device.
