Lean: AI Macro Tracker is an iPhone app that streamlines nutrition logging by combining intuitive design with artificial intelligence. It helps users track calories and macronutrients with minimal fuss, supporting goals like losing weight, building muscle, or maintaining a balanced diet.

• Upload photos of your plate and let the app interpret items and estimate their caloric and macro content.

Intelligent meal analysis

Lean’s AI Meal Scanner analyzes images or logged items to estimate calories and macronutrient breakdowns automatically, reducing manual calculations. The engine refines its predictions over time and provides clear breakdowns so you can see exactly how each meal contributes to daily targets.

Exercise syncing and calorie adjustments

Whether you do structured gym sessions, daily mobility routines, or home bodyweight circuits, these inputs help tailor your targets to what you actually burn.

Tracking progress and insights

Detailed charts and weekly summaries reveal trends in calorie intake, macronutrient balance, and weight changes. Customizable reports highlight areas to improve and celebrate milestones, keeping motivation high as you move toward your health objectives.
