Lean

Calorie tracker that estimates real metabolism via AI body-fat photo scan.

Mobile appfreemiumglobal

Lean is a calorie tracking app that measures body fat with a five-second AI photo scan and estimates basal metabolic rate from a person's actual lean mass rather than generic formulas, modeling metabolic adaptation over time. Meals can be logged by AI photo, barcode, or database on iOS and Android, aimed at people who want a more individualized metabolism estimate than typical calorie apps provide.
