FAQ

Questions & Answers

Xamarin enables the development of native apps for different platforms using the same programming language and tools. Another advantage is that a large part of the app logic, such as server communication and business rules, can be reused across platforms. Apps created with Xamarin offer near-native performance and are more efficient than hybrid or web apps. Xamarin also provides access to native APIs and functions, which is particularly advantageous for complex apps.

With .NET MAUI, you can develop apps that run on different platforms. It supports the creation of native user interfaces for each platform and offers a consistent user experience. Changes can be made during the app's runtime, which reduces development time. .NET MAUI is tightly integrated with Visual Studio, creating an efficient development environment.

The following points highlight the efficiency and flexibility that Xamarin and .NET MAUI offer for developing modern applications

  • Cross-platform development
  • Uniform programming language
  • Native user experience
  • Code reuse

We offer comprehensive support during the development process, particularly in the area of cross-platform app development for Android and iOS. We offer services such as the development of warehouse logistics apps, integration into existing teams to overcome bottlenecks, project management, and consulting.

Cayas Software positions itself as a full-service partner and values high-quality and cost-effective solutions.

Yes, we can convert existing Xamarin apps to .NET MAUI. To do this, we update projects to SDK-style projects and dependencies to .NET 8. For further insight, you can find an article on our blog page about the 7 steps for migrating from Xamarin Forms to .NET MAUI.

App development times can vary. A basic app could be ready in just 3 weeks, an app with multiple features could take 6 months, and a highly customized app could even take over a year to develop.

Cayas Software GmbH has developed a wide range of cross-platform apps covering various industries and use cases. The types of apps they have developed include:

  • Warehouse logistics apps: These apps optimize warehouse processes and improve efficiency in logistics.
  • Driver apps: Developed for delivery services to enable drivers to navigate safely and efficiently.
  • Voice command integration: Implementation of voice commands in apps to increase user-friendliness.

In addition, we offer training and support for teams who want to expand their app development skills.

Yes, absolutely! At Cayas we don’t just stop at releasing the app — we also provide ongoing support and maintenance afterwards. Depending on your needs, this can include monitoring, updates, bug fixes, performance improvements, or even further feature development. Our goal is to ensure your app continues to run smoothly and grows with your business. Typically, we offer flexible post-release support models:

  • Maintenance contracts with a defined scope and service levels
  • Flexible support packages with a set amount of hours per month you can use as needed
  • On-demand support if you prefer to request assistance only when necessary

This way you can choose the model that best fits your business and ensure long-term stability for your app.
