Mobile App Cross-Platform Migration

How SICO VENT Expanded Market Reach by 50% Through Strategic Cross-Platform Migration

The SICO VENT app by SIMON PROtec provides seamless Bluetooth control of SICO‑HUB‑BT modules and connected PA actuator drives, allowing precise operation of windows and smoke/flap systems. Designed to integrate with SIMON PROtec’s ventilation and fire-safety solutions, the app enables easy monitoring, accurate positioning, and efficient management of building smoke and ventilation systems.

Challenges

The original SICO VENT application was built exclusively for Android using Kotlin, severely limiting the potential user base and preventing iOS users from accessing the window ventilation control system. This platform limitation resulted in missed market opportunities and increased customer support complexity. 

Solutions

We executed a complete application rewrite using Flutter designed to modernize the codebase and enable cross-platform deployment through unified architecture. Built with performance and maintainability in mind, it offers seamless functionality across both mobile platforms from a single codebase.

  • 100% feature parity with the original Android app
  • True cross-platform support for Android and iOS
  • Stream-based communication architecture
  • Enhanced state management
  • Reactive UI updates working seamlessly across both platforms
  • Single codebase reducing development and maintenance overhead
