Weight is one number. Your body is the story.
On GLP-1, the scale moves fast, but the scale doesn't tell you whether you lost fat or muscle. Phaze v3.1 imports your DEXA scan and tracks body fat %, lean mass, and bone density over time, so you see the body composition story alongside your weight.
At a glance
- Phaze imports DEXA reports as PDF or photo and extracts body fat %, lean mass, fat mass, bone density, and regional breakdowns automatically.
- Studies show GLP-1 users can lose up to 40% of weight as lean muscle without protein and resistance training.
- Manual body composition entry is free; DEXA scan import and trends are Premium.
- Body composition is stored AES-256-GCM encrypted on device and in iCloud backup. Never sold or used to train AI.
- Best paired with quarterly DEXA scans, most US clinics charge $50-$150 per scan.
- Available on iOS 17+, Android, and Apple Watch (watchOS 10+).
Beyond the bathroom scale
DEXA scan import
Snap a photo or import the PDF from your DEXA appointment. Phaze pulls body fat %, lean mass, fat mass, bone density, and regional breakdowns automatically.
The metrics that matter
Body fat percentage. Lean mass (kg or lbs). Bone mineral density. Visceral fat. Trended quarter over quarter.
Body comp + weight, together
See your weight trend with body composition overlaid. When the scale stalls but lean mass climbs, you'll know it's a win.
Yours alone, encrypted
Body composition is AES-256-GCM encrypted on device and in backup. Never sold, never shared.
Why body composition matters more than weight
Two people at the same weight can have completely different bodies. Composition tells the truth.
Lean mass loss is the silent risk on GLP-1, protein and resistance training matter, and DEXA is how you confirm they're working.
DEXA is the gold standard. More accurate than scales, smart mirrors, or BIA cuffs.
Track once a quarter, see the real story. You don't need monthly scans to see meaningful change.

What this means
Body fat down, lean mass holding, exactly what you want on GLP-1. The protein and resistance work is paying off.

Frequently asked
No. Manual entry is free, log body fat %, lean mass, and weight from any source you have, including a smart scale. DEXA scan import is the premium fast path.
Most major cities have DEXA clinics that charge $50-$150 per scan. Search "DEXA scan near me" or ask your doctor. Body Spec, DexaFit, and Fit3D are common chains in the US.
Every 3 months is typical for active weight loss. Once you stabilize, every 6-12 months is plenty. Phaze trends as much or as little data as you give it.
GLP-1s reduce appetite, which means it's easy to under-eat protein and lose lean mass alongside fat. Lean mass burns calories, supports your metabolism, and protects you long after you taper. Watching it is non-negotiable.
Yes. AES-256-GCM encrypted on device and in iCloud backup. Never sold, never shared, never used to train AI.
Track the body, not just the number.
Free for manual entry. Premium for one-tap DEXA import.
