24/7 Blood-Glucose Monitoring App
A patient-friendly app that turns a sub-dermal glucose sensor's live data into clear readings, alerts and trends.
The challenge
Our client, a healthcare technology firm specialising in blood-glucose monitoring, had built a sensor that sits under the skin and tracks glucose continuously. Unlike a traditional glucometer it produces a constant stream of data. To take it to market they needed a mobile app that could process those readings in real time, be effortless for patients of any age, and handle health data with privacy built in.
Our approach
We ran an in-depth requirements analysis covering both the sensor's technical specification and the real-world needs of patients and carers. We then designed and built a cross-platform app on React Native, with a Node.js backend that ingests sensor data over MQTT and runs on AWS.
Key features
Real-time readings
Live glucose values streamed from the sensor and shown with clear in-range status.
Proactive alerts
Instant notifications for patients and their care circle before levels go out of range.
Trend visualisation
Charts that transform complex sensor data into insights patients can act on.
Privacy by design
Secure cloud architecture designed around healthcare data-privacy requirements.
The app turned the client's sensor technology into a market-ready, user-friendly product, making continuous monitoring and decision-making accessible to everyday patients.
