What is a Cross-Platform App?

Do you want an app that works on all major devices—iPhone, Android smartphones, tablets, and even PCs or Macs—without having to be developed multiple times? That's exactly what we deliver with cross-platform app development, based on modern, proven technology.

With just one codebase, we create an app that works everywhere and feels like a native application. This not only saves time and money but also ensures that users have a consistent, familiar experience, regardless of the device.

Frequently Asked Questions about .NET MAUI

From simple tools to large, data-intensive apps, we implement unique solutions. The platform offers comprehensive options for integrating databases, APIs, cloud services, and native device features like the camera, GPS, or Bluetooth.

Even demanding business logic, complex user interfaces, or offline functions can be reliably implemented. The shared codebase not only makes development more efficient but also more consistent across all platforms. For businesses, this means powerful, future-proof applications, even with high requirements.

Cross-platform apps are applications that work on multiple operating systems, such as Android, iOS, Windows, and macOS. Instead of developing a separate app for each platform, a single app is built to run on all devices.

This is where .NET MAUI comes in: the technology allows you to develop apps for different platforms with a single, shared codebase. This not only saves time and money but also ensures a consistent user experience, whether the app is used on a mobile device or a desktop computer.

In many cases, yes—especially if the apps were developed with Xamarin. We are happy to assess this for you on an individual basis.

Looking for technical information on migrating from Xamarin.Forms to .NET MAUI? In our detailed blog post, our experienced Xamarin developers share exciting details.

As an official Microsoft standard, .NET MAUI is actively developed and supported. Thanks to its close integration with proven tools like GitHub, Visual Studio, and Azure, development and deployment processes run smoothly. .NET MAUI is a future-proof technology for efficient app development.

At Cayas, we start every project with an individual analysis and provide you with a realistic time estimate early on, including milestones for your planning security. As a general guide:

  • Simple apps: Applications with basic functions (e.g., forms, lists, simple navigation) can often be developed in 4 to 8 weeks.
  • Medium-sized projects: Apps with specific business logic, data integration, or user accounts typically require 2 to 4 months.
  • Complex applications: For extensive projects with multiple modules, offline functions, APIs, cloud services, or custom UI concepts, development can take 6 months or longer.

That depends on the scope of the features. We'll be happy to give you a transparent estimate in an initial consultation.
