Fitzenia Macro Calorie Tracker

Calorie and macro tracking with AI meal photos and adaptive TDEE targets.

Fitzenia helps you track calories and macros, understand your real TDEE, and follow body-composition progress without turning every day into a pass/fail score.

Log food your way: search foods, scan barcodes, save custom foods and meals, or use AI meal photo logging when a photo is faster. Review the nutrition estimate, adjust ingredients or portions, and log the meal with confidence.

Your target should learn from your body. Fitzenia uses your logged calories and weight trend to estimate adaptive TDEE, then helps keep calorie and macro targets aligned with the direction you choose: lose weight, gain weight, maintain, or recomposition.

Progress is more than today's scale number. Track weight, body fat, BMI, weekly calories, goal pace, and progress photos. Compare photos side by side or with a slider, so you can see changes that daily weigh-ins may hide.

What you can do in Fitzenia:
- Track calories, protein, carbs, fat, fiber, sodium, sugar, and saturated fat
- See daily calorie targets and macro progress
- Search foods, scan barcodes, save custom foods, and build saved meals
- Estimate meals from food photos with AI, then review and edit before logging
- Follow adaptive TDEE as your logged data improves
- Track weight, body fat, BMI, weekly calories, and goal pace
- Save progress photos by date and pose, then compare changes over time

Fitzenia is built for people who want clear nutrition data, flexible tracking, and calmer progress feedback. Whether you are cutting, gaining, maintaining, or recomping, the app helps connect what you log today with the trend your body is actually showing.

Fitzenia does not replace medical advice. Nutrition and AI estimates should be reviewed by you before use.
