About Lean - Weight Loss Tracker
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. APPLE WATCH & SIRI • A full Apple Watch app: calories left at a glance, your usual meals in one tap, water and a fasting timer • Complications and Smart Stack widgets for calories, your fast, water and your streak • Say "Log a meal in Lean" to Siri, then just say what you ate • Your fast runs live on the Lock Screen and in the Dynamic Island FREE FOREVER • Daily weight log, trend charts & streaks • Apple Health sync • 2 AI meal scans every day • One AI coach question every day • A fresh AI insight every week, built from your own data • Today's meals from your personalised plan • CSV export & daily reminder LEAN PRO • Unlimited AI meal scans • A personalised AI insight every morning — not once a week • Unlimited coach chat • A full 7-day meal plan and shopping list, built around your allergies and taste • Plateau detection with AI diagnosis • Pace coaching and a forecast to your goal date • 7-day moving average and body-fat estimate Your health data stays yours. Lean never sells your data and never shows ads. The AI coach runs on-device with Apple Intelligence where available. Lean Pro is available as a monthly or yearly auto-renewing subscription. The yearly plan starts with a 7-day free trial. Payment is charged to your Apple ID account. Subscription renews automatically unless cancelled at least 24 hours before the end of the period.
