About SarVita - Longevity Tracker
What Is Sarvita
Sarvita is an iOS app that works as a personal longevity coach. It pulls sleep, heart rate, workouts and body weight from Apple Health, combines them with the meals you log, and turns that pile of numbers into two plain figures: your biological age and your Age Pace, which is how fast you're aging right now against your calendar age. An AI assistant named Sar, short for Sarvita, walks you through the results and suggests what to adjust.
The pitch is simple. Most health trackers hand you charts and leave the interpretation to you. Sarvita does the reading for you. It scores your food the way a nutritionist would, marks a meal as good or bad for your age pace, and points at the one habit worth fixing today instead of listing everything at once.
The biggest limitation is platform. There's no Android app and no web dashboard, so you need an iPhone, and the biological age math leans on Apple Health data from an Apple Watch or iPhone sensors. Data stays on your device and in your own private iCloud, which is good for privacy but means switching to Android later would leave the app behind.
Getting Started
- Download Sarvita from the App Store and allow read access to Apple Health, which feeds sleep, heart rate and workout data into the app.
- Take the free biological age test, a 39-question check that takes about three minutes and asks for no email.
- Log a few meals, either by snapping a photo or typing a short description, so the AI can score their nutritional quality.
- Open the Age Pace screen after a week of data to see which of the 19 tracked factors are pulling your pace up or down.
- Talk to Sar in the chat when you want a plain explanation of a number or a nudge on what to change next.

Key features
Biological Age Score
Sarvita estimates a biological age from 19 factors, drawing on Apple Health signals like resting heart rate, sleep, activity and body weight alongside what you log in the app. The figure moves as your habits change, so it works as a long-term gauge rather than a one-time quiz result. It's an estimate for motivation and tracking, not a clinical measurement.
Age Pace
Age Pace is the app's speedometer. Where biological age tells you where you stand, Age Pace shows how fast you're currently aging against your calendar age, so you can tell whether recent choices slowed you down or sped you up. Sarvita splits your factors into ones already built into your history and the 10 you can still move today, which makes the target clear.
AI Meal Logging and Scoring
You log food by taking a photo or typing a short description, and the app scores the meal's nutritional quality, flagging it as good or bad for your pace. It grades against a diet-quality model rather than raw calories, so a bowl of vegetables and a candy bar don't score the same even at equal energy. The goal is fewer spreadsheets and more honest logging.
The Sar Assistant
Sar is the in-app AI coach. Ask it why your number moved or what to eat after a hard workout, and it answers using your own logged data instead of generic advice. It leans on the Gompertz math behind the aging model, so its explanations tie back to how the score is actually built.
Apple Health Sync
The app reads sleep, heart rate, workouts and weight straight from Apple Health, which cuts manual entry to a minimum for anyone already wearing an Apple Watch. You grant access once, and the data feeds the longevity model automatically from then on. It reads from Health but doesn't write to it, so your Health records stay as they were.
On-Device Privacy
Sarvita computes its scores on your iPhone and syncs through your own private iCloud database, so the developer doesn't hold your health records on a server. You can export meals, workouts, weight, calories burned and sleep as CSV, JSON or Markdown whenever you want. Deleting the app clears the local copy, and you can wipe the iCloud copy from settings when you're ready.
Pros and cons
Pros
- Turns Apple Health data and meal logs into one biological age score, so you don't interpret charts yourself.
- Age Pace separates factors you can still change from ones already baked in, which points at what's worth doing today.
- Meal logging works from a photo or a short typed note, so it's quick enough to keep up with.
- Health data stays on-device and in your own iCloud, and you can export or delete it yourself.
- The 39-question biological age test is free and needs no email, so you can try the core idea first.
Cons
- There's no Android version or web dashboard, so iPhone and Apple Watch owners are the only ones who get the full experience.
- You'll need to log meals for the food scoring to work, and the app leans on Apple Health data for its numbers.
- Biological age is a motivational estimate, not a medical test, so it shouldn't replace a doctor or lab work.
- Pricing is a subscription handled through Apple, and the app doesn't publish a fixed public price on its site.
