Muscle Log: Workout & AI Coach

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
