Modern technology & cross-platform know-how
The iOS operating system is widely used in the B2B environment. Anyone who wants to have an iPhone app programmed or have an iPad app programmed can reach sophisticated target groups with high willingness to pay, provided the app is built on stable and future-proof technology.
Cayas Software GmbH has been developing custom iOS apps for a wide variety of industries for over twelve years. We combine a well-thought-out user experience (UX) with efficient implementation in .NET MAUI. With this Microsoft technology, much of the code can be developed once and used for multiple platforms.
From planning and app design for iOS to the completion and follow-up support of your project, we are your reliable partner.
Our experts plan and develop the implementation of your app for iPhones, iPads, and MacBooks, or as a web application.
We plan, design, and develop iOS apps entirely according to your needs. You decide in what form our iOS app agency and iPad app agency support you.
In iOS development, we rely on native interfaces and APIs for the highest quality in every step of the process.
Develop Great Apps Yourself
Increase the satisfaction of your target audience with a user-friendly iOS app.
Two Paths to Your iOS App
At Cayas, you decide how you want to have your iOS app developed: as a complete service by our development team, or as targeted reinforcement for your existing project team.
All-Around Service from Your iOS App Agency
One option is for our development team to take over the entire project. We plan, design, and program your iOS app and continue to support it after the go-live.
Expert as a Service
A second option is to support an existing project team until the go-live, without any further follow-up support. In both cases, we attach great importance to working in a customer-oriented and high-quality manner.
Whichever form of cooperation you choose, our experts will drive the realization of your ideas with passion.
Learn More About Flexible Collaboration
Over time, we have specialized in two main areas of app development. On the one hand, we develop in-house apps to increase process efficiency, and on the other hand, we create customer loyalty apps that digitally expand existing products. Whether you want to develop an iPhone app or have an iPad app built depends on the use scenario for your employees or customers.
Of course, our experts are also the right contacts for other types of iOS apps and develop custom solutions with dedication and foresight. Whether you want to modernize your iOS apps, build out an existing iPhone application, or add new features, we support you with the same level of competence.
Discuss iOS App Development for FreeCross-Platform Projects with .NET MAUI
We rely on .NET MAUI (the successor to Xamarin) when you want to have an iPhone app programmed and an iPad app programmed at the same time. This produces cross-platform solutions from a shared codebase. We design the user interfaces of the apps in XAML, which allows us to work very efficiently and save around 30 percent in development time and costs.

FAQ
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:
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.
Our services at a glance:
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 develop software, build new iPhone apps, or modernize existing iOS solutions, our expertise offers strong advantages:
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:
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.
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.
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.
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. For a detailed overview of cost drivers, realistic price ranges, and savings potential, see our page on app development costs.
