Workout-Class Heart Rate Streaming Application

I need an iOS application developer experienced in integrating smartwatch health data, particularly in real-time tracking of metrics for fitness classes. The application is intended to monitor each participant's heart rate and display the readings on a central monitor in real time as part of a workout class setting. There will be two types of end users. One will be the workout participant and the other will be the gym owner. The gym owner will want to track how certain individuals perform over time and during certain workouts. The idea here would be that gym owners could tie metadata to each workout to say what was the average heart BPM, max heart BPM, what was the average amount of time people were in zone 4 cardiovascular, etc. Key Requirements: - Fetch and stream real-time heart rate data from Apple Watch to a central application tied to each gym - Display metrics including calories burned, current heart rate, and more on a dashboard that will be accessible through the gym owner's application. - Allow for each gym owner to tie certain trainers to certain workouts. This will allow trainers to see how people perform during their workouts. Desired Skills: • iOS Application Development • HealthKit integration • Real-time data processing • Experience in fitness-related app development will be a plus point.
