## What is Pip?

Your scale can't tell fat from muscle. Pip can help you see the difference.

Take two photos a week — front and side — and Pip estimates your body fat as a range, then tracks how it changes over time. Lost fat but gained muscle while your weight stayed flat? Pip shows that recomposition.

HOW IT WORKS
• Prop up your iPhone and step back. Pip guides you out loud with a 10-second timer.
• On your iPhone, Apple's Vision framework finds your outline. Pip estimates your waist from the front and side photos and applies Relative Fat Mass (Woolcott & Bergman, Scientific Reports, 2018), a formula validated against DXA scans, adjusted with DXA data from over 11,000 adults (NHANES).
• You get a body fat range — honest about uncertainty — and a weekly trend.

FEATURES
• Body fat % estimate range from two photos
• Weekly trend chart
• Fat vs. lean mass breakdown
• A gentle weekly check-in rhythm with forgiving streaks
• Weekly recap, plus a card you can share (no body numbers on it)
• Works with Apple Health: read height, weight, birth date and sex, and save body fat estimates to Health
• English, Portuguese and Spanish

PRIVATE BY DESIGN
Your photos are analyzed on your iPhone and never uploaded. They're excluded from backups and can be locked with Face ID.

GENTLE BY DESIGN
No red numbers, no "ideal body", no daily weigh-ins. Pip, our mascot, cheers for consistency — never for a number.
