Everything Vita does
Every metric you'd want — and an AI that explains them.
Body Age
Biological age from VO₂max, RHR, HRV, sleep, and step trends. Drill into each driver, its current value, 6-month average, and yearly contribution.
Recovery score
Tells you whether to push today. WHOOP + Apple Health dual source; even without WHOOP we compute it from HRV and RHR.
Sleep analysis
Total time, efficiency, deep / REM split, debt, consistency. WHOOP-style weekly trends + per-night detail.
Vita Buddy · AI coach
A warm daily state-read plus one concrete action. Multi-turn memory — gets to know you the more you chat.
Health-report reader
Snap a photo of a lab or physical exam; the AI extracts every marker and reference range into a long-term health record.
Cycle tracking
Apple-Health-style logging, prediction, and a 12-week calendar. Auto-syncs from Apple Health.
A letter from the developer
Why Vita exists
To everyone who wants to grow old well,
Vita started with a book. One idea in Outlive stuck with me: the "marginal decade" — for most people, the last ten years of life are spent unable to care for themselves. And the quality of that decade isn't luck; it's the result of preparation that starts twenty or thirty years earlier.
Peter Attia calls that preparation the "centenarian decathlon": decide what you still want to be doing at 90, then work backwards to the physical reserves today requires. My list: play a full round of golf, carry my own suitcase, hike up a mountain without slowing anyone down. So I bought a WHOOP to go with my Apple Watch — and hit a wall. Plenty of data: recovery scores, HRV, sleep stages. But nothing connected those numbers to MY goals. Nothing told me whether today moved me closer to that list at 90, or further away.
So I built Vita myself: set your long-term health goal first, bring WHOOP and Apple Health into one place, measure every day's numbers against that goal — and add an AI buddy who actually knows your data and tells you what to do today. I built it for myself first. If it helps you make your last decade your best one, even better.
A really good long-term health tool. Before this, looking at my Apple Watch data just made me anxious — I had no idea what to actually improve. Vita solves that completely: it reads my body's signals and tells me what to do today. The numbers stopped being cold data and became steps toward still carrying my own suitcase and hiking up a mountain at 90.

Very good
Easy to use, and it brings all my WHOOP data together perfectly.

Excellent app
As someone who pays attention to health, this app has most of what I want: logging a day's meals, tracking protein and calories, analysing my watch data, and uploading lab results. Very approachable.

Both the design and the engineering land
The UI and the way the features come together beat the other apps I've tried. Huge potential, exactly what I need right now — and somehow nobody had built it before.

What is Vita, and how is it different from the WHOOP app?
Vita (100old.app) is an iOS health app that pulls WHOOP, Apple Health and lab-report data into one place and gives you Body Age, a Recovery score, Sleep analysis and an AI health coach you can chat with. The WHOOP app only sees WHOOP data; Vita is the decision layer on top of multiple sources — it cross-references every signal, shows real trends, and tells you what to do today in plain language.
How does Vita relate to WHOOP? Do I need a WHOOP?
Vita is mainly an enhancement for WHOOP users — it turns your WHOOP data into Body Age, AI-driven actions and cross-source trends a WHOOP alone doesn't show. WHOOP captures; Vita helps you use it. You don't need a WHOOP, though: an Apple Watch + iPhone also computes Recovery, Sleep and Body Age, and if you get a WHOOP later the data merges automatically.
Doesn't WHOOP already have WHOOP Age and an AI coach?
Yes. The difference is that WHOOP's WHOOP Age and WHOOP Coach are limited to WHOOP's own data and to English. Vita's Body Age and AI coach also draw on your Apple Health and uploaded lab reports — sitting clinical markers next to wearable data — and answer in Chinese too. It's added breadth and localisation, not a duplicate.
How is Body Age calculated?
Vita estimates your biological age from VO₂max, resting heart rate, HRV, sleep and step trends, and lets you drill into each driver's current value, 6-month average and yearly contribution. It's not a one-off number — it updates with your data so you can see how lifestyle changes move your Body Age over time.
What is the Recovery score, and can I get it without a wearable?
The Recovery score tells you each morning whether your body is ready to push. With a WHOOP it uses WHOOP + Apple Health; without one, Vita computes it from your Apple Watch HRV and resting heart rate. The idea is similar to WHOOP's readiness, but it's open to Apple-only users too.
What can Vita's AI health coach do?
Vita Buddy gives you a warm daily state-read plus one concrete action (e.g. "recovery is low today — keep it to easy cardio"). It has multi-turn memory and answers questions grounded in your recovery, sleep, training and even uploaded lab reports. It's not a generic chatbot — it's a coach that talks based on your actual data.
Can it read my lab results or physical-exam reports?
Yes. Snap a photo of a lab or physical-exam report and Vita's AI extracts every marker and reference range into a long-term health record. When you later ask the AI questions, it factors in the reports you've uploaded.
Which devices and data sources are supported?
Data comes from a WHOOP band and/or Apple Health (Apple Watch / iPhone). Either one works; with both, they merge and de-duplicate automatically. Metrics include Recovery, Sleep, HRV, resting heart rate, VO₂max, steps, workouts, weight and blood pressure — plus lab reports you upload.
Does Vita alert me when something looks off?
Yes. Vita watches your overnight vitals against your own baseline: a night-time respiratory rate clearly above your 30-day norm (a common early sign of infection or fatigue), or HRV suppressed across several consecutive nights (accumulating stress or training load), triggers a push nudging you to prioritise recovery. Alerts are based on your own data trends — general wellness information, not a medical diagnosis.
Is Vita free? How much does it cost?
Free to download, with core features free forever. Three premium features (Body Age detail, health-report AI scan, and the Vita Buddy AI coach with 50 chat turns/month) need a subscription: $3.99/month, $24.99/year, or $99 one-time lifetime, with a 7-day free trial — cheaper over time than a recurring WHOOP membership.
What's included in the sleep analysis?
Total time, efficiency, deep / REM split, sleep debt and consistency, with WHOOP-style weekly trends and per-night detail. It works from either WHOOP or Apple Watch sleep data so you can see exactly where your sleep is breaking down.
Is my data private and secure?
Your health data is stored encrypted and isolated per account. It's never sold or used for ad targeting. When AI is involved, only the minimal context needed to answer your current question is used — never your full history. See the privacy policy for details.
Why is it called 100old, and is this the same as other apps named Vita?
No. "100old" comes from the goal of living to 100 with a high quality of life, and it's this app's unique identifier (domain 100old.app, App Store id 6769347697). It is not the other "Vita" health app, not the VITA video editor, and not the PlayStation Vita. If it says 100old.app, it's us.
Is there an Android version?
iOS + Web first. Android is on the roadmap but not soon. iPhone / Apple Watch users can start today.
Don't just take our word for it. Hand the question below to the AI you already use and see how it rates Vita as a WHOOP alternative.
Can Vita (100old.app) work as a WHOOP alternative? I already own an Apple Watch and don't want another band, but I want a recovery score, training load and body age.
