FAQ

Questions and Answers

UX Design (User Experience) ensures that your app is easy to understand, intuitive, and pleasant to use. It's about guiding you and your users smoothly from the first interaction to the goal. UI Design (User Interface) makes your app visually attractive and unique—through colors, fonts, icons, and visual elements that reflect your brand. The interplay of UX and UI is crucial: only when design and user experience harmonize perfectly does an app emerge that delights and is used long-term.

Yes—we develop custom apps for both Android and iOS. We choose the best approach for your project: native development for maximum performance or cross-platform solutions like .NET MAUI/Xamarin for efficient development of both platforms. So you can be sure your app will run stably, perform well, and reach all users in your target audience—without compromising on quality or design.

First impressions matter: in the first few seconds, a user decides whether to keep or delete your app. A professional UI design conveys trust, quality, and your brand identity. We ensure that your app not only looks great but also offers clear user guidance. This increases acceptance, return visits, and recommendations—making your app a real success factor for your business.

Yes, definitely! At Cayas, we don't just stop at publishing the app—we also offer ongoing support and maintenance. Depending on your requirements, this can include monitoring, updates, bug fixes, performance improvements, or even the development of new features. Our goal is to ensure that your app runs smoothly and grows with your business. We typically offer flexible support models after publication:

  • Maintenance contracts with a defined scope and fixed service levels
  • Flexible support packages with a fixed number of hours per month that you can use as needed
  • On-demand support if you only want to request help when you need it

This way, you can choose the model that best suits your company and ensure the long-term stability of your app.
