After an in-depth evaluation of various technology stacks, we chose React Native, Laravel and MySql Server Database as the development platform. The technology stack has IOT programming and integrations, and custom reports are now automated.
SmartCare IoT— Development & Integration of Health Monitoring System
.A healthcare startup approached Digital Dividend to develop a modern solution that connects medical devices with a mobile application. Their goal was to help patients track daily health readings and allow doctors to monitor conditions in real-time. The previous system relied on manual entries, paper records, and inconsistent communication.
Digital Dividend built a complete IoT ecosystem that links hardware devices to the app, automates record generation, and enables doctors to access patient data instantly.

Executive Summary
Before this project, there were no available devices that could sync with a mobile application. All readings were manually entered. Patients had no reminders for medications, and families were not notified during emergencies. Doctors also lacked a unified dashboard to review patient progress.
We solved this by integrating IoT hardware with a multilingual mobile application. The system automatically reads device data, stores it, organizes it by category, and sends alerts. Doctors and family members receive updates via email, SMS, or in-app notifications.
The Challenge
The client faced several operational issues:
1. No automated device connectivity
All health readings were entered manually. There was no way to sync medical devices with a phone.
2. Data inconsistency
Different types of reports were stored separately, making it difficult to track progress.
3. No reminders or scheduled alerts
Patients had no system to remind them of medication times or follow-up tests.
4. No emergency support
If a reading reached a dangerous level, families and doctors had no automatic notification.
5. Doctors lacked real-time patient records
Doctors were unable to check reports quickly because everything was on paper.
These limitations created delays, errors, and risk for patients.
Our Solution
Digital Dividend built an advanced IoT-enabled healthcare system with three major components:
1. IoT Device Integration
We programmed the system to connect the device through Bluetooth and audio-jack technology.
The app automatically:
- Reads values from the sensor
- Converts them into digital form
- Saves them inside the user’s account
No manual entry needed.
2. Automated Records & Cloud Storage
Each reading generates a new record instantly. All reports are grouped into categories such as:
- Sugar level
- Blood pressure
- Temperature
- Oxygen saturation
This makes tracking health history simple and reliable.
3. Alerts & Emergency Notifications
The system sends alerts to:
- Patient
- Family members
- Doctor
Alerts are customizable via:
- SMS
- Push notifications
During emergencies, alerts are sent immediately.
4. Doctor Dashboard & Monitoring Tools
Doctors can:
- View patient records anytime
- Track progress trends
- Download reports
- Handle multiple patients from one panel
This improves diagnosis accuracy and response time.
Technology Stack & Rationale
Frontend (Mobile App)
- React Native for both iOS and Android
- Clean UI for fast navigation
- Offline reading mode
Backend
- Node.js
- Secure REST APIs
- Device SDK integration
IoT Layer
- Custom logic to read, decode, and process medical device output
- High accuracy data mapping
- Real-time cloud sync
This stack ensured speed, stability, and smooth hardware connectivity.
