Info

Category :Mobile App Development

Industry:HealthTech, IoT, Wearable Devices

Introduction

PAX Africana – Co-Health is a mobile health application built for Android, integrated with the Linktop 6-in-1 smart medical device. It is designed to enhance healthcare access and quality in rural and underserved communities across Africa by enabling real-time patient monitoring and efficient health data management by frontline health workers.

Client Requirements

The client required a solution that could integrate with the Linktop 6-in-1 smart medical device, support offline field usage, and provide a centralized admin panel with role-based access. They also needed data visualization, health trend analytics, and real-time geo-tagging to improve decision-making, tracking, and efficiency.

Key features of Co-Health

01

Real-Time Device Integration

Instantly captures six key vital signs including ECG, BP, and glucose levels.
02

Health Worker Toolkit

Enables patient registration, vitals logging, medication recording, and follow-up scheduling during field visits.
03

Patient-Centric Access

Patients can view health history, manage appointments, and access services even without the app.
04

Admin Dashboard

Role-based access for monitoring, analytics, and population-level health insights.

Challenges and Approach

  • Low Connectivity in Rural Areas – Ensuring offline functionality and data sync when back online.
  • Device Integration Complexity – Achieving seamless real-time data capture from Linktop device.
  • User Accessibility – Designing for low-literacy users and ensuring usability for both health workers and patients.
  • Data Security & Accuracy – Protecting sensitive patient data and ensuring precision in geo-tagged reporting.

  • Human-Centered Design – Focused on user-friendly interfaces tailored for health workers and rural patients.
  • Modular Architecture – Enabled scalability and smooth integration with the Linktop device and future add-ons.
  • Pilot Testing in Field – Validated performance in low-resource settings, with health workers providing real-time feedback.
  • Improved Health Outcomes – Enabled better tracking of chronic conditions, improved access to care, and streamlined health service delivery.
