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/

You keep stepping on the scale and reacting to a single number. Up two pounds, day ruined. Down one, false hope. The number never tells you whether you're heading in the right direction. Luff does. Set a goal. See your trend. Get an honest calorie target that adapts to your real results, not a generic formula. No food logging. No meal photos. No streaks. No coach trying to be your friend. Weight tracking is a small job done daily, and Luff treats it that way. Have a normal weekend without the app sulking about it. Plot a new course from where you actually are, not where you wish you were. How it works Pick a direction: lose, gain, or maintain. Step on your scale; Luff syncs with Apple Health. Hit your goal and Luff shifts you to maintenance automatically. What's included: Weight logging with Apple Health sync. A smoothed trend line instead of daily noise. Week, month, quarter and all-time views. Drift alerts when your trend leaves the corridor. Adaptive calorie targets. Goal predictions. Insights on energy balance, movement, sleep, exercise and logging consistency. Home screen and Lock Screen widgets. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is update cadence: BuffMeter at every 4 days against Luff's fortnightly. BuffMeter also leads on iOS requirement (18.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
