You can reverse your biological age. Not with supplements or biohacks — with the right training and the right food. Sarvita turns Apple Health into a biological age, rates every meal you eat, and gives you an AI coach with one goal: making that number go down. Your biological age isn't fixed. It's the sum of your VO2 Max, heart rate variability and body composition — all metrics you can improve. Sarvita calculates yours, then tells you every day whether you are aging faster or slower than the calendar. AGE PACE — ONE NUMBER FOR TODAY Biological age is the odometer. Age Pace is the speedometer: how fast today is aging you, from your sleep regularity, your training, your steps and what you ate. 1.00 is neutral; below it, you are banking time. Every factor is grounded in published research, and the app shows you the math. MEALS RATED, NOT JUST COUNTED Snap a photo or describe what you ate. Sarvita logs the calories and macros — then rates the plate: • Every meal gets a badge — Good, Mixed, Watch out or Neutral — with the reasons behind it • Every food shows how processed it is, from whole food to ultra-processed • Your day gets a diet-quality score out of ten against a typical adult, built on the AHEI-2010 index from Harvard • Fibre, total sugar and saturated fat are written to Apple Health with your macros • Nudges respect your diet: vegan, vegetarian, halal, kosher, low-FODMAP, gluten-free, nut allergies Disagree with a rating? Correct it with a tap. AN AI COACH WHO READ YOUR PLATE Sar's daily check-ins and weekly nutrition reports speak from the same ratings you saw on screen — the salad at lunch gets its credit, the sugary snack gets called what it is. Every week, your coach delivers a personalized training plan: specific sessions based on your current fitness and where you need to improve. TRACK YOUR BIOLOGICAL AGE See exactly how old your body is — and watch it get younger: • VO2 Max Age — the strongest predictor of longevity • HRV Age — your nervous system's resilience • Body Composition Age — muscle vs fat distribution Monthly snapshots show your progress. The goal is simple: be biologically younger next month than you are today. THE FIVE PILLARS THAT REVERSE AGING Zone 2 Cardio — Builds the mitochondrial density that slows cellular aging. Auto-detected using your personalized heart rate zones. VO2 Max Training — The single best thing you can do for longevity. Track your VO2 Max trend and see it climb. Strength Training — Muscle is your longevity reserve. Lose it and you age faster; build it and you reverse the clock. Stability Work — Prevents the injuries that derail progress. Yoga, pilates, flexibility, core — it all counts. Nutrition — Not calories alone: the quality of what you eat, rated meal by meal, day by day. SEE YOUR TRANSFORMATION • VO2 Max trending upward over months • Diet quality as a trend, not just today's number • Weight moving toward your goal • Training consistency visualized Every chart answers one question: am I getting younger? BUILT FOR PEOPLE WHO ARE SERIOUS No social features. No trophies. No streaks. Just an AI coach, the metrics that matter, and a clear path to a younger biological age. In 23 languages.
