## Description

New Sleep Tracking (Premium): Apple Watch scores your sleep quality. Plus a daily Recovery tip, a muscle body map, and shareable cards

Muscle Log is a workout tracker built around one goal: helping you stay consistent.
  
■ Effortless logging
- Start a session in one tap from a template—your last weights and reps carry over automatically
- Log on Apple Watch alone, even offline, then auto-sync to iPhone 
- See your progress by muscle group, personal records, and a training calendar
  
■ AI Personal Coach (Coach plan)
- Get "today's workout" tailored to your history and goals
- Chat about form, plateaus, and motivation
- Receive daily meal plans with PFC (protein/fat/carb) balance
- Just snap a photo of your meal to auto-log calories and nutrition
- Get an automatic weekly review report every Sunday
  
■ Privacy
- Detailed logs stay on your device. Only summaries and coach conversations go to the cloud
- Meal photos are discarded right after AI analysis 
- You can delete your account and data anytime from within the app
  
Note: The numbers and suggestions in this app are study aids and estimates only. They are not a substitute for medical diagnosis or treatment.
  
The Coach plan is an auto-renewing subscription: ¥780/month or ¥7,800/year, with a 7-day free trial. Cancel anytime.
