Why Lean, if you study kinesiology, nutrition or sports science

Most apps still estimate your basal rate with 1919 formulas and a vague activity level. Lean measures each component of your expenditure: TDEE = BMR + NEAT + EAT + TEF, with metabolic adaptation modeled separately as a coefficient on the basal rate.

BMR on real body fatBasal metabolic rate recomputed continuously from your body fat percentage, with a patented proprietary model, not from age and weight alone.
NEAT from your stepsEverything you burn outside training, derived from your daily step count via HealthKit or Google Fit.
EAT per workoutExercise energy expenditure from your tracked sessions, session by session.
TEF from your macrosThe thermic effect of food computed from what you actually ate, not a flat 10%.
BodyScan AIYour body fat percentage from a single photo, the input that makes every other number accurate.

Three ways to log food: a 2 million product database (USDA and Open Food Facts), barcode scanning, and AI photo recognition of a plate. Rated 4.7/5 on the App Store and 4.5/5 on Google Play by 10,000+ users.
