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.

Verdict
The clearest difference is rating: ProteinLog at 5.0 against BuffMeter's 4.4. BuffMeter's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (7 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. BuffMeter sells 3 in-app purchases, starting at $2.99 per 7 days and ProteinLog sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
ProteinLog holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: BuffMeter has 7 ratings behind it against 1, so its average is the more settled of the two.
BuffMeter ships an update every 4 days, ProteinLog weekly. The most recent releases landed on September 24, 2026 and September 20, 2026 respectively.
