You want to look better in the mirror. But you can't tell if what you're doing is working — or where to even start. Buff Meter fixes that. Snap a photo, and AI breaks down your physique in seconds — how lean you are, which muscles are developed, which ones are lagging, and exactly what you'd look like if you committed to a transformation. SEE WHAT YOU'RE WORKING WITH Every scan scores your chest, back, shoulders, arms, legs, and core individually. You'll know exactly where you're strong and where you're falling behind. Your overall Buff Score tracks your physique from Untrained to Genetic Freak — so next time you scan, you'll know if you actually improved. SEE WHAT YOU COULD LOOK LIKE Pick a goal — lose fat, build muscle, or both — and the app generates an AI image of your future physique. Not a generic model. Your body, transformed. It's the version of you that's 12 weeks of consistency away. BUILD THE HABITS THAT GET YOU THERE Personalized daily targets for sleep, water, calories, protein, and training. Check them off as you go — or let Apple Health fill them in automatically. You'll see exactly which days you showed up and which ones you didn't. WATCH YOURSELF CHANGE Charts for body fat, weight, and Buff Score over weeks and months. The kind of progress that's invisible day to day becomes obvious when you have the data. FREE TO START Your first body scan is free. Daily check-ins and progress charts included. BUFF METER PREMIUM Unlimited scans, goal visualization, and full Apple Health sync. Weekly, yearly, or lifetime. Stop wondering. Get your score. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
