# Sweat Loss Tracker: Smart Hydration Monitoring System

The Fluid Loss Tracker is an advanced hydration monitoring system for endurance athletes.  
It combines a Garmin DataField and a companion mobile app (iOS/Android) to deliver real-time, personalised fluid loss estimates during training and racing.

# Overview

This system tracks and predicts your sweat loss during endurance activities such as cycling and running.  
Using machine learning, it analyses workout data, environmental conditions, and personal physiology to display real-time hydration insights directly on your Garmin device.

Note: For best visibility, use the DataField in a 2-field screen layout or on a dedicated screen.

# How It Works

## Garmin DataField
- Displays real-time fluid loss estimates on your bike computer  
- Shows temperature and location information when available  
- Collects live activity metrics and sends them to the mobile app  
- Receives calculated fluid loss predictions from the app  

## Companion App (iOS & Android – BETA)
- Uses machine learning to calculate personalised fluid loss estimates  
- Analyses metrics such as heart rate, power, speed, temperature, humidity, and duration  
- Displays live and historical workout statistics  
- Stores activity history for continuous model improvement  
- Adapts to multiple activity types including road cycling, mountain biking, indoor training, and running  

# Key Features

## Real-Time Monitoring
- Continuous data transmission between Garmin device and smartphone via Bluetooth  
- Live fluid loss estimates updated automatically during workouts  

## Smart AI Predictions
- Cloud-based machine learning models analyse more than 15 physiological and environmental metrics  
- Three model tiers:
  - Pre-trained: Generic predictions based on sweat rate categories (light, medium, heavy sweater)  
  - Personalised: Custom model trained on your own historical data  
  - Auto: Automatically selects between personalised and pre-trained models based on activity similarity
