About

Project Lean

Read full description

Project Lean is nutrition coaching that names patterns. Most calorie trackers leave you alone with the numbers. Project Lean is different. You scan your meals, and the AI estimates macros automatically. Then it watches the patterns: which days you fall off, which foods you reach for under stress, where your week falls apart, what's actually moving your goals forward. Every day, you check in. The AI coach reads everything: today's meals, your patterns this week, your goals, your weak spots. It names what it sees. Sometimes it pushes back. Always concrete, never generic. Once a week, Insights pulls it all together: habit consistency, mood trends, what's working, what isn't. Project Lean is designed for people who already know nutrition basics and want something to think alongside them, not a tracker that just counts. WHAT YOU GET - AI meal scanning from photos: point your camera at the plate, log the macros - Macro estimation with confidence ratings so you know when to double-check - Daily check-ins for habits, mood, stress, and cognitive patterns - AI coach with full context: your profile, your week, your history - Lean Brain chat: open-ended questions, coach-quality answers - Weekly Insights with pattern recognition across habits and mood - Streak tracking with reset day support (planned cheat days don't break your streak) - Meal templates for foods you eat on repeat - Push reminders at your chosen daily time WHO IT'S FOR People serious about their nutrition who want a thinking partner, not a database. Works for cutting, bulking, recomp, or just keeping yourself honest. PRIVACY Your data stays yours. Meal photos, check-ins, and chat messages are private to your account. We never sell or share your data with advertisers. Sign in is required so your data syncs across devices and you can recover your account. SUPPORT Questions?
