Requirement:​

The client needed a mobile application that could seamlessly interface with their custom-built hour meter devices. These devices are designed to monitor and log key operational metrics of industrial equipment, such as total usage time, periods of activity or inactivity, and even trigger audio or visual alerts when thresholds are met. The primary goal of the app was to make this data easily accessible to the user, with intuitive visual representations and downloadable reports. The client emphasized simplicity and offline usability, ensuring the app would remain functional even without continuous internet access.

Solution​

We developed a cross-platform React Native mobile app capable of receiving real-time data from the hour meters via UDP, HTTP, and MQTT protocols, ensuring compatibility with diverse network environments. The app stores all incoming data locally in a structured database, enabling offline access and analysis. A dynamic visualization module was implemented to present equipment usage statistics through interactive bar charts, allowing users to quickly assess performance trends. In addition, we included a CSV export feature that compiles the usage logs into downloadable reports for further analysis or archival purposes. The app was optimized for low-latency data handling and supports multiple device connections simultaneously.
