Body Tracking
Track your body transformation.
Generic body tracking apps don't understand GLP-1 weight loss. Phaze tracks what matters — body composition, muscle preservation, progress photos, and the habits that make your transformation permanent.
Progress Photos with Ghost Overlay
Guided body tracking photos with ghost overlay for perfect pose matching. Four comparison modes — side-by-side, ghost overlay, slider, and grid — let you see your body transformation over time with clinical precision.
Weight Trends & Body Composition
Sync with any Apple Health-compatible smart scale to track body fat percentage, lean mass, BMI, and weight trends. See how your body composition changes throughout your GLP-1 journey — not just the number on the scale.
Muscle Preservation Tracking
The #1 concern for GLP-1 users is muscle loss during rapid weight loss. Phaze sets protein-first goals and tracks intake with AI meal scanning to help preserve lean mass while losing fat.
Milestone Celebrations
Watch your body change over weeks and months with a visual timeline. Share milestone cards that celebrate your transformation without ever revealing you're using weight loss medication.
Frequently asked questions
Unlike generic body tracking apps, Phaze is purpose-built for the rapid body changes that happen on GLP-1 medications like Ozempic, Mounjaro, Wegovy, and Zepbound. It combines progress photos with ghost overlay, protein-first nutrition tracking for muscle preservation, body composition insights via Apple Health smart scale integration, and a 5-phase progression system that adapts as your body transforms.
Phaze tracks body composition through multiple methods: guided progress photos with 4 comparison modes (side-by-side, ghost overlay, slider, and grid), weight trends synced with Apple Health and compatible smart scales that measure body fat percentage, and protein intake tracking to monitor muscle preservation. You can see your full body transformation timeline in one place.
Yes. Research shows GLP-1 users can lose significant muscle mass during rapid weight loss. Phaze helps prevent this by setting protein-first nutrition goals (0.7-1.0g per pound of body weight), tracking your daily protein intake with AI meal scanning, and providing visual progress photos so you can monitor body composition changes beyond just scale weight.
Phaze's progress photos use guided positioning prompts for consistent framing across sessions. The ghost overlay feature shows your previous photo transparently so you can match your exact pose. This creates accurate, comparable body tracking photos that show real transformation - not just different angles or lighting.
Yes! Phaze has bidirectional Apple Health (HealthKit) integration. It reads weight, body fat percentage, BMI, and other body composition data from any Apple Health-compatible smart scale. It also syncs steps, active minutes, heart rate, sleep, and workouts - giving you a complete body tracking picture.
Absolutely. All body tracking data - progress photos, weight, body measurements, and medication information - is AES-256 encrypted and stored in your iOS Keychain. Premium users can optionally back up to iCloud Drive with AES-256-GCM encryption — even Apple can't read your data. Nothing is shared with analytics. Phaze looks like a premium fitness app - no one will know you're tracking GLP-1 progress.
