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.

Verdict
The clearest difference is update cadence: Lean at every 3 days against CaloScan's every 5 weeks. Lean also leads on device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
