Know what your food is really doing to your metabolism. Peaty is the first AI-powered food analyzer built entirely around Ray Peat's pro-metabolic nutritional philosophy. Snap a photo of any meal, product label, or restaurant dish — and get an instant, honest score with the full reasoning behind it. THE PEATY SCORE Every food gets a 0–100 Peaty Score based on what actually matters: saturated vs. polyunsaturated fat ratios, thyroid-supportive nutrients, and anti-metabolic ingredients like seed oils and soy. No calorie obsession. No low-fat dogma. Just the framework Ray Peat spent decades refining. · Peaty Approved (80–100) — eat freely · Mostly Peaty (60–79) — solid, with minor caveats · Tread Carefully (30–59) — has pro-metabolic downsides · Not Peaty At All (0–29) — foods Peat strongly cautioned against AI FOOD SCANNER Point your camera at anything — a plate, a nutrition label, a takeaway container — and the AI identifies every visible ingredient, estimates macronutrients, and scores the whole picture in seconds. No barcode needed. THE PEATY GURU Have a real conversation about your diet. Ask about specific foods, understand why seed oils are problematic, get more pro-metabolic alternatives, or attach a recent scan for targeted advice. The Guru answers with nuance, not bullet points. DAILY & WEEKLY TRACKING See your average Peaty Score for the day, weekly trends, calorie and macro breakdowns, and keep your scan streak alive. Over time you build a clear picture of where your diet is strong — and where it needs work. RAY PEAT POSITIVES & NEGATIVES Every scan surfaces the specific ingredients that help or hurt your score, with plain-English explanations grounded in Peat's thinking. You'll always understand the why. FREE TO START Download Peaty and get 5 complimentary AI scans — no credit card, no commitment. When you're ready to scan freely, upgrade to Peaty Unlimited for unrestricted use, or grab a one-time scan pack. —— Peaty is an informational tool, not medical advice.

Verdict
The clearest difference is in-app purchases: GymSheet at none against Peaty App's 3. Peaty App's advantage is update cadence (every 3 weeks vs every 21 months) and iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.
