Track calories, macros, and body composition like someone who actually wants results — not just a daily score. Fitzenia is an adaptive nutrition tracker built for cuts, bulks, maintenance, and recomp. Most apps lock you into a generic calorie target. Fitzenia learns your real daily energy needs from your weight trend and food log, then keeps your targets honest as your body changes. ADAPTIVE TDEE THAT LEARNS FROM YOU Your true daily energy expenditure (TDEE) gets recalculated from what you actually eat and how your weight actually moves. Cut harder, bulk smarter, maintain confidently — without resetting your plan every two weeks. AI BODY TRANSFORMATION PROJECTION Set a goal. See a realistic timeline. The AI body projection translates your starting point, pace, and goal into an honest week-by-week forecast of how your body is likely to change. No fantasy timelines. No before/after fiction. AI MEAL PHOTO LOGGING Snap a photo of your plate or pick one from your library, and the AI estimates calories, protein, carbs, and fat. Edit ingredients or portions before logging — you stay in control of what hits your diary. BARCODE SCANNING — ALWAYS FREE Scan any product code for instant nutrition data. Build custom foods with full macro and micro fields. Save your repeat meals and re-log them in one tap. BODY-FIRST PROGRESS Track weight, body fat percentage, BMI, weekly average calories, and goal pace in one clean trend view. Daily fluctuations stop being noise and start being signal. FOUR-POSE PROGRESS PHOTOS Take front, side, other-side and back photos and tag them by date. Pull up a side-by-side compare or a slider view to see the changes a scale will never show you. PHASES THAT MATCH YOUR GOAL Cut, bulk, maintain, reverse diet, or body recomposition. Switch when your goal changes — macros, calorie targets, and pace adapt automatically. APPLE HEALTH INTEGRATION Connect to Apple Health to import weight, steps, active calories, and exercise. Your daily nutrition plan respects what you've actually done today. AI INSIGHTS Short, data-aware notes about your trend — calm, supportive, never preachy. Available on supported devices.
