## Description

FluidLoss.info: sweat-loss estimates and hydration metrics in one app. Clear recaps after every session. Personalised accuracy that improves with you.

FluidLoss.info is the companion app for estimating sweat loss and guiding hydration during and after workouts. 
Pair it with the FluidLoss data-field on your Garmin device to get real-time fluid-loss estimates while you ride.

How It Works
Install the FluidLoss data-field on your Garmin device from the Connect IQ Store. During a workout, the data-field collects metrics—heart rate, duration, temperature, intensity—and sends them to the companion app. The app runs a machine-learning model to estimate how much fluid you're losing in real time. When you finish, you get a clear recap with a chart of fluid loss over time and key stats like duration, distance, and training effect.

Key Features
- Real-time fluid-loss estimates displayed on your Garmin and phone
- Post-workout recaps with charts and summary stats
- Personalised predictions that improve as you provide feedback

Personalisation
The base model works out of the box. After several sessions, you can provide actual fluid-loss measurements (weigh yourself before and after) to train a personalised model that accounts for your unique sweat rate. The more and better data you provide, the more accurate your estimates become.

Importing Activities
Already have Garmin activities? Share a Garmin Connect activity link to the app and provide the fluid loss for that session—no need to redo the workout.

Requirements
A Garmin Edge device that supports Connect IQ (Edge 840, 850, etc.)
The FluidLoss data-field installed from the Connect IQ Store
iOS 11 or later
