What is Lean?
LEAN tracks both calories in and true calories out. Snap a photo to log meals, use AI body-scan for body-fat, and get real-time metabolic burn based on BMR, NEAT, EAT & TEF. Adaptive algorithm adjusts as your metabolism changes for smarter fat loss.
Problem
Users previously relied on manual calorie tracking methods and static metabolic rate estimates, which required tedious manual logging and led to inaccurate body-fat measurements and unadaptive calorie burn calculations that don’t account for metabolic changes over time.
Solution
A mobile app combining AI-driven photo-based meal logging, body-fat analysis via AI body scans, and real-time adaptive metabolic tracking. Users can snap meal photos, monitor body composition, and receive dynamic calorie burn data adjusted to metabolic shifts.
Customers
Fitness enthusiasts, dieters, and health professionals (e.g., nutritionists, personal trainers) seeking precise, automated tracking of body metrics and metabolic changes.
Unique Features
Unique integration of AI body-scan for body-fat analysis and adaptive algorithm adjusting calorie burn calculations based on real-time metabolic shifts (BMR, NEAT, EAT, TEF).
