About the client
Our client is a powerhouse gym chain in the US.
Their emphasis on fostering a sense of community and creating a motivational environment ensures strong member retention and a solid presence in the market.
Business challenge
The client aimed to improve the fitness experience and make it safer by implementing a mobile app for comprehensive health monitoring that would ultimately promote personalized, healthier fitness experiences.
The core of our client’s app — heart rate monitoring — presented a unique challenge. This feature demanded an accurate and reliable method of measuring users’ pulse without relying on external devices. Variations in tap precision, user technique, and environmental factors could affect the accuracy of readings, impacting the reliability of the results.
Beyond accuracy, our client aimed to increase health heart awareness among fitness enthusiasts by providing in-app guidance.
Delivered solution
Facing the client’s strict accuracy requirements for heart rate management, Orangesoft’s team developed a transformative fitness application that accurately measures the user's heart rate in real time using a smartphone camera.
Thanks to tailored algorithms and color filters, the app obtains real-time heart rate measurement with accuracy rivaling dedicated hardware.
Custom algorithm for precise heart rate monitoring
At the heart of the application there is a customized algorithm that recognizes facial pulses by analyzing video from the user's face or a finger placed on the camera lens to accurately track and calculate heart rate. The algorithm calculates the saturation of green pixels on the face or finger through the camera and registers the peaks between them, which correspond to the pulse.
Key features
The app provides instant feedback on the heart rate, offers insights into heart recovery times, and delivers personalized fitness recommendations to enhance heart health.
Real-time heart rate monitoring
The app enables real-time heart rate monitoring with minimal latency, ensuring users receive immediate feedback on their heart rate.
Heart recovery insights
By analyzing users’ heart rate data, the platform can provide insights into users' heart recovery times and offer guidance on optimizing recovery for better heart health.
Pulse recognition
Using a smartphone camera, a customized in-app algorithm analyzes pixel changes in the user’s face or finger to register pulse peaks. Filtering and data smoothing improve the algorithm’s accuracy, even for users with darker skin tones.
Personalized fitness recommendations
The platform analyzes users' heart health data, activity levels, and goals to generate personalized fitness recommendations, including exercise types, durations, and intensities tailored to improve heart health.
