Snap a photo of any meal — Lean's AI counts the calories and macros in seconds. No searching food databases, no weighing, no barcodes, no typing. Then Lean goes further than any calorie counter: it explains WHY your weight changes — not just that it did. And you can ask it anything. HOW IT WORKS • Point your camera at your plate → AI estimates calories, protein, carbs & fat • One tap logs it to your daily calorie budget • Step on the scale each morning and log your weight in 10 seconds • Lean syncs your steps, sleep and burned calories from Apple Health automatically • Your AI coach connects the dots: "You're up 0.4 kg, but you slept 5 hours and had 3,100 mg extra sodium — that's water, not fat." • Ask your coach a question any day — "why am I stalling?", "what should I eat tonight?" — and get an answer built from your real numbers WHY LEAN WORKS Most apps show you numbers. Lean interprets them. Weight fluctuates daily for reasons that have nothing to do with fat — Lean's coach knows your sleep, steps and meals, so it can tell the difference and keep you steady through plateaus. Setup takes two minutes and asks what actually trips you up — cravings, late-night eating, diets that didn't stick before — so your plan fits your life from day one. STAY ACCOUNTABLE Invite a friend to Lean, cheer each other on, and join community challenges for streaks, steps and consistency. Streak Shield covers a day you miss, so one slip doesn't undo weeks of progress.

HOW TO USE LEAN: 1) Take four photos and let the AI read your body in about a minute. 2) Find out exactly which muscle group is holding you back. 3) Train the plan built around that weak point, not a generic split. Most fitness apps track what you do. LEAN tracks what you're made of. The scan estimates your body fat percentage and scores nine areas out of 100: overall, potential, body fat, chest, back, shoulders, biceps, triceps and core. No tape measure. No calipers. No clinic appointment. A single body fat number tells you very little on its own. Knowing your back is sitting ten points behind your shoulders tells you what to do on Monday. That's the difference. Direction instead of guesswork. Your calorie and macro targets are built from your own scan, your weight, and how you actually spend your day. Walk more and the target moves with you. Say what you ate out loud and LEAN logs it in seconds. Training programmes are aimed at your lowest scores. Log your sets as you go. Personal records are detected automatically. An AI coach that has seen your numbers, your targets and what you've actually been lifting. Not generic advice with your name pasted on top. Scan again in a few weeks and see exactly what moved. BEING STRAIGHT WITH YOU LEAN produces estimates, not laboratory measurements. Body composition worked out from photographs will differ from a DEXA scan. What it's good at is consistency. Scan the same way each time and the direction of change is reliable, which is the part that matters when you're training. YOUR PHOTOS Analysed, then deleted, within minutes. Never kept, never looked at by a person, never used to train AI models. Delete your account and everything in it from inside the app whenever you want. You don't just train. You train with direction. Your body is unique. Your plan should be too. Download LEAN and find out where you actually stand. SUBSCRIPTION LEAN Premium is required to use the app. Your first scan is free. Monthly: $9.99 per month Annual: $34.99 per year Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless turned off at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings. LEAN is a general fitness and wellness app. It does not diagnose, treat, cure or prevent any disease or medical condition, and nothing in it is medical advice. Always consult a doctor or other qualified health professional before making decisions about your health, and before starting or changing how you eat or train — particularly if you have any medical condition.
