## What is GRS Trainer Watch?

GRS Trainer is a sports training app for youth athletes, built for Apple Watch.

Train smarter with structured drill libraries for basketball and lacrosse — wall ball, shooting, passing, ground balls, footwork, and more. Every drill includes a countdown timer, coaching notes, and hand-specific guidance (right, left, or both).

Features:
- Basketball and lacrosse drill libraries
- Countdown timer for every drill
- Coaching notes and technique cues
- Session builder — create your own workouts
- Team challenges — race to 10,000 shots or compete for most minutes trained
- Leaderboards to compete with teammates
- HealthKit integration — tracks heart rate, calories, and workout data
- Works independently — no iPhone required

Built for athletes who want to put in the work.
