Most calorie trackers stop after you log a meal. Recomp AI helps you understand what to change next. Built for body recomposition, Recomp AI connects food logging, protein, macros, weight trends, body measurements, and daily reviews into one feedback loop so you can lose fat, build muscle, or maintain with fewer guesses. Track calories and macros through AI chat: - Type what you ate - Use voice - Snap a photo of your meal - Scan a barcode - Ask the AI to search the web for specific nutrition information when needed - Log however you want. Be as precise as you want. The system adapts to you. Recomp AI connects daily intake to long-term outcomes. See how today’s food affects your progress. Track changes in bodyweight and body measurements. Use trends instead of reacting to daily noise. Your data feeds a simple loop: log, analyze, adjust. Daily and weekly reviews show what changed, by how much, and why. When progress stalls, the AI suggests small corrections. When things are working, it tells you to stay the course. Measurement -> review -> adjustment. Compounded over time. --- We don't provide medical advice. Please consult with a healthcare professional in addition to using this app and before making any medical decisions.
