## What is Longevity Tracker?

You can reverse your biological age. Not with supplements or biohacks — with the right training and nutrition. Sarvita combines AI-powered meal tracking with the exact workout protocols used by longevity researchers, then shows you whether it's working.

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 gives you an AI coach focused on one goal: making that number go down.

AN AI COACH FOCUSED ON RESULTS

Every week, your coach delivers a personalized training plan — not generic advice, but specific sessions based on your current fitness and where you need to improve. Accept the plan, follow it, watch your biological age drop.

Weekly nutrition reports show what's working and what isn't:
• Are you hitting your protein targets?
• How diverse is your diet?
• When are you eating, and does it matter?
• How does your intake correlate with weight changes?

Daily check-ins keep you accountable with insights tailored to your data.

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 FOUR PILLARS THAT REVERSE AGING

Zone 2 Cardio — Builds the mitochondrial density that slows cellular aging. Sarvita auto-detects these 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.

Each goal card expands to show coach tips, your workout history, and the science behind why it matters.

NUTRITION THAT SUPPORTS LONGEVITY

Log meals in seconds with AI:
• Snap a photo or describe what you ate
• Meals save instantly — analysis happens in background
• See exactly where your calories and macros land

Choose your mode:
• Losing fat? Track your deficit
• Building muscle? Monitor your surplus
• Maintaining? Hit your target

Your energy balance updates in real-time: calories in versus calories burned.

SEE YOUR TRANSFORMATION

• VO2 Max trending upward over months
• Weight moving toward your goal
• Training consistency visualized
• Body composition improving

Every chart answers one question: am I getting younger?

What's new in 1.18.3:

- Added Cardio Recovery to the workout detail screen — see how quickly your heart rate drops after a hard effort, right alongside avg HR, max HR and pace.

- Improved app performance and reduced freezing, especially around meal photos and the Fuel tab.

- Fixed a bug where the Sar coach kept generating the same weekly training plan over and over instead of reusing it.
