# SwimTune — AI Swim Training Platform

> SwimTune is an AI-powered swim training platform that creates personalized, adaptive workout plans for swimmers of all levels — from beginners to elite competitors. It launches on Apple Watch and iPhone in Spring 2026, with Garmin and Google Wear OS integrations planned.

## What SwimTune Does

SwimTune turns swim data into intelligent training plans. It uses data from your Apple Watch — including stroke rate, split times, SWOLF, heart rate, and recovery metrics — to build training sessions that adapt to your body, goals, and progress.

The platform includes:
- An AI coach that explains every session in plain language
- Adaptive training plans that adjust session-by-session based on recovery, performance, and goals
- Real-time swim metrics: 12+ data points captured automatically during each swim
- Health integration: sleep quality, HRV, and recovery data shape workout intensity
- Zone-based training (Z1-Z5) with automatic pace zone calculation via CSS testing
- Periodized training blocks with race peaking for competitive swimmers
- Progress analytics and journey tracking

## Supported Swimmer Levels

- **Beginner**: New to structured swimming. Plans start at ~800m sessions with drill demos, plain-language coaching, and focus on comfort/habit building. CSS test introduced at weeks 6-8.
- **Intermediate**: Comfortable with all strokes, swim regularly. Plans include CSS testing, pace zones, threshold training, and technique work.

- **Elite**: National/international level. Full periodization with taper protocols, race simulation, and competition peaking.

## Competitive Differentiation

SwimTune differs from MySwimPro, FORM Goggles, Garmin Swim, and Strava by offering truly adaptive AI-driven plans — not generic workout libraries. Every session adjusts based on the swimmer's actual recovery state, recent performance data, and long-term training goals.
