🍽️ AI Food Scanner & Instant Calorie Counter
Snap a photo of your meal! Our 🤖 Calorie AI (Cal AI) instantly recognizes food items and breaks down calories, macronutrients (protein, carbs, fat) and micronutrients. The fastest, most intuitive food journal and meal tracker you'll ever use.

🚶 Seamless Activity & Step Tracker

Lean automatically calculates your Total Daily Energy Expenditure (TDEE) from its core components:
BMR (Basal Metabolic Rate): calories your body burns at rest.
EAT (Exercise Activity Thermogenesis): calories burned during workouts.

the worst app ever, they gave you many questions, then they forced you to subscribe before trying it, and that a waste of time, i will not subscribe if i don't try it first. and why too many questions if I can't use it without subscribing. so I don't recommend it at all. there are other apps better, and it's free for try.

looks great on first impression but there's no option to switch units of measurement. It's annoying to have to switch apps just to convert kg to lbs.
