Case Study
With the Alarm Control Center developed in Germany, Alarm IT Factory GmbH offers state-of-the-art alerting software that securely and efficiently transmits messages from process control and visualization systems to a wide range of end devices.
With the ACC app for iPhone, iPad, Apple Watch, and Android devices, messages can be displayed, processed, and acknowledged — with additional features that make alerting more convenient and user-friendly.
Our team supported Alarm IT Factory GmbH to deliver a more robust and future-proof solution:
Reliable, fail-safe alerting was critical. Dual control and intensive testing ensured feature parity post-migration. Push notification reliability via Apple and Google was essential to avoid missed critical alerts.
The existing team (three developers) had started the migration but hit obstacles. To prevent duplicate work, Xamarin.Forms development was paused and MAUI migration was prioritized. Cayas .NET MAUI experts accelerated delivery under time pressure, modernized the codebase, and worked around framework issues.
The architecture used a REST API, push notifications, and SignalR. MVVM separated presentation and logic; custom renderers were ported to MAUI handlers; reusable controls were adopted where possible.
We managed delivery via an issue tracker for clarity and pace. Work included migrating views, replacing custom renderers with handlers, ensuring data migration, and designing/implementing a modern dark mode. Extensive refactoring reduced redundancy and improved maintainability.
Comprehensive testing across devices and platforms ensured the .NET MAUI app matched the Xamarin.Forms version and offered smooth functionality on Android and iOS.
Within one month, the team achieved functional parity with the old app and significantly improved the codebase — enhancing stability, maintainability, and future velocity.
“Thanks to the perfect advice and technical support from Cayas Software, we implemented the migration of our ACC app in less than half the planned time — and even made further improvements.”
They’re complementary but distinct:
In short: UX makes it work seamlessly; UI makes it look and feel great.
Yes. We build high-quality apps for both iOS and Android using modern cross-platform frameworks as well as native development where it makes sense — ensuring excellent performance and a consistent experience.
UI is your first impression. Clear, attractive interfaces increase user trust, reduce errors and support costs, and positively influence activation and retention — directly impacting revenue.
Absolutely. We provide ongoing support and maintenance — monitoring, updates, bug fixes, performance improvements, and feature development. Choose the model that fits your needs:
