AI Health & Balance App

Wellance is an application powered by AI that allows its users to monitor their vital signs, track their health metrics, and get personal wellness tips. It acts as a complete digital assistant that combines the capabilities of heart rate monitoring, blood pressure logging, blood sugar tracking, weight management, and AI health consulting. With the help of such features as AI food scanning, white noise, and Apple Watch integration, Wellance helps its users to establish healthy behaviors and live a healthy life.

What We Provided

We implemented the services of targeted integration and enhancement for the platform Wellance. We integrated the feature of AI Health Consultant, implemented the feature of AI Food Scanner, optimized the connection of Apple Watch to synchronize health metrics, improved the algorithm of heart rate monitoring, and performed bug fixing and performance optimization.

Integration Approach

Being a service-based IT company, we did not develop the core application from scratch. We just extended its functionality using system integration and API orchestration.

The Challenge

Optimizing the Wellance platform through integration required addressing several key challenges:

  • line icon

    Integrating AI Health Consultant

    The users needed personalized health consultation based on their health data and individual objectives. Required integration of the AI-powered system capable of analyzing user data and generating personalized recommendations.

  • line icon

    Integrating AI Food Scanner

    The users needed to scan their meals to evaluate the caloric value and nutritional details. Required integration of computer vision and nutritional database APIs.

  • line icon

    Connecting with Apple Watch

    The health metrics needed to be seamlessly synchronized with Apple Watch for improved insights. Required efficient integration with Bluetooth technology.

  • line icon

    Heart Rate Measurement Accuracy

    The users needed heart rate measurement using smartphone cameras. Required algorithm adjustment for consistent measurements along with user instructions.

  • line icon

    Consolidation of Health Metrics

    The platform needed consolidation of manually entered data related to blood pressure, oxygen levels, blood glucose, weight, and BMI.

  • line icon

    User Retention and Engagement

    Health apps have issues with retaining their users. Required insights and personalized recommendations for the user-friendly interface.

Our Solutions

Our Solutions

AI Health Consultant

We have incorporated an AI-based health consultation feature which provides customized advice on the basis of user health metrics and health goals. Our AI analyzes the heart rate, blood pressure, blood sugar levels, body weight, and other health metrics to give customized advice.

AI Food Scanner

We have also introduced the feature of computer vision and database incorporation for the AI Food Scanner. By using this, the user is able to scan their food to know the number of calories in it and other nutritional information. Our app also generates AI-based meal plans according to the dietary needs of the user.

Enhanced Integration with Apple Watch

We have enhanced the integration of our app with the Apple Watch. By this, the user will be able to get more accurate health metrics.

Improvement of Heart Rate Monitoring Algorithm

In order to improve the accuracy and stability of heart rate measurement we have optimized the algorithm that tracks your heart rate. Detailed guidelines were introduced to get the most accurate results by using the application: keeping the device stable, covering its back camera with your finger and not moving while measurements are performed. The application supports real-time monitoring of the heart rate and HRV.

Health Metrics Tracker

All the health metrics were gathered in one tracker and now users can track their blood pressure, oxygen levels, blood sugar, weight, BMI and calories consumption during the day. Trend analysis allows users to see the state of their cardiovascular health and glucose levels.

Relaxation & Sleep

Calming white noise functionality was added to the application to allow users to relax and get good sleep.
