Snap a photo of any meal and get calories instantly — no searching, no guessing. 2 free AI scans a day, and your streak keeps going even on days you skip the scale.
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

Love insights and reminders. Also meal calorie scanner. Oh and breath exercises.
Your streak doesn't need a scale any more.
• A meal scan, a logged meal, a check-in or a measurement all keep your streak going — weighing in is optional
• Log straight from your daily reminder with one tap, without opening the app
• Your coach now notices when tracking stops, when you're moving less than usual, and when you're doing well — and says something useful about it
• A new feedback card on your dashboard goes straight to the founder
Reminders are shorter and clearer throughout.
