Mobile Application Modernization for Off-Road Suspension Control
Rootstack modernized Arnott’s legacy React-based mobile application for iOS and Android,
improving its stability, scalability, user experience, and compatibility with modern
devices and in-vehicle systems.
About the Client

Arnott is a manufacturer specializing in adjustable air suspension shock absorbers for off-road vehicles such as Jeeps. The company focuses on providing technological solutions designed to improve vehicle performance and the driving experience in demanding environments.
Arnott had a legacy mobile application developed in React for iOS and Android that needed to evolve to support new functionalities, devices, and vehicle control capabilities. Rootstack was selected to modernize the application while maintaining compatibility with the existing suspension hardware and preparing the platform for future expansion.
Challenge
The existing application presented several limitations that made continued development increasingly complex:
- Difficulty implementing new features due to outdated technology.
- Compatibility issues with modern devices and platforms.
- Risk of instability when updating dependencies and framework versions.
- Complexity in integrating advanced vehicle control functionalities.
- Need to support tablets and in-vehicle environments such as Apple CarPlay.
The main challenge was to modernize the application without affecting its compatibility with the existing suspension system hardware, while creating a more scalable foundation for future product development.
Our Solutions
Rootstack designed and implemented a comprehensive technology modernization strategy focused on transforming the existing React mobile application into a more robust, scalable, and future-ready platform.
The first stage involved a complete update of the React-based application, including refactoring legacy code, updating critical libraries and dependencies, optimizing the application lifecycle, and implementing a more modular architecture. These changes established a stronger foundation for maintenance, security, performance, and future feature development.
Rootstack also redesigned the application architecture to clearly separate business logic, presentation, and hardware integration. This structure made it possible to incorporate new functionality without unnecessarily affecting the application's core and prepared the platform for future integrations with additional devices and accessories within the Arnott ecosystem.
A key component of the project was the integration with the vehicle's suspension and diagnostic systems. Rootstack developed communication interfaces with air suspension systems, implemented real-time control for suspension height adjustments and driving modes, integrated OBD systems to capture vehicle speed and technical data, and enabled remote control through RF technology.
The application was also enhanced with intelligent control capabilities designed to improve the off-road driving experience. These included automated suspension lowering when the vehicle was turned off, management of driving modes and off-road configurations, control of accessories such as lighting for extreme terrain, manual controller brightness adjustment, and a "Show" mode for demonstrations and visual configurations.
To expand device compatibility, the application was optimized for smartphones and tablets, including iPad, with interfaces adapted for larger screens. Integration with Apple CarPlay enabled direct control through the vehicle's system, while connectivity improvements such as the "scan again" functionality simplified device reconnection.
Rootstack also improved the overall UX/UI through a more intuitive navigation flow, faster access, auto-login functionality, clearer interfaces for technical controls and system monitoring, and reduced friction when connecting to vehicle devices and hardware.
The modernization resulted in improved application performance and stability, broader compatibility across smartphones, tablets, and in-vehicle systems, and a technology platform prepared for future innovations within Arnott's product ecosystem.
The solution was built using React for mobile, iOS, Android, OBD system integration, and Apple CarPlay.
