Snap it, scan the barcode or just type it: calories and protein in seconds. Barcodes are always free, plus a new companion for GLP-1 shot days.
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.

Developer Response
Thank you for the support!
New in this version:
• Log from anywhere: new controls for Control Center, the Lock Screen and the Action button. Scan a meal, add water, start a fast or log your weight with one press.
• A simpler Today: one + button logs anything, and what matters today sits on top.
• Your meals can go to Apple Health too, with calories, protein, carbs and fat.
• GLP-1 companion: link Apple Health, and the doses you mark as taken there show up as shots in Lean.
• Streaks now count meal days too, with a 3-days-a-week goal and a Streak Shield you can see.
• Up after a hard workout? Lean tells you when it's most likely water.
• Made for bigger screens: two columns on iPad and the new iPhone Duo.
• Fixes and improvements.
