Built for wearable users

You have the data. Now find out what to do with it.

Your HRV, sleep quality, and recovery scores tell a story — but your apps just show you charts. Vitanzo reads your data and gives you one clear directive each morning: here's what your body needs today.

iOS 16 or later. Your data never leaves your device.

Data without direction isn't insight. It's noise.

Vitanzo is built around one problem: sophisticated trackers have more data than ever and still don't know what to do each day.

One clear directive, every morning

Based on last night's HRV trend, sleep stages, and recovery score, Vitanzo tells you exactly what kind of day your body is ready for — push hard, train easy, or prioritize rest. No interpretation required.

Your data stays yours — fully

Vitanzo reads directly from Apple Health, Oura, and Whoop — the sources you already trust. All analysis runs on your device. Your biometric data is never uploaded, never sold, never seen by us. All analysis runs locally using Apple's on-device frameworks. Vitanzo makes no network calls to our servers.

Patterns your apps won't show you

Daily scores are noisy. What matters is the direction of your health over months and years. Vitanzo tracks longitudinal trends in VO2 max, resting HRV, and sleep quality — and flags meaningful shifts before they become problems.

Early beta testers

Real data. Real shifts.

Our early testers came in with years of wearable data and no clear picture of what it all meant. Here's what they found.

"I've had an Oura Ring since 2022 and I was drowning in data. Vitanzo was the first thing that actually told me why my HRV tanks after a certain type of week — not just that it had dropped."

"My sleep quality score improved by 18% over six weeks — not because Vitanzo changed what I do, but because I finally understood which habits were actually moving the needle. The longitudinal view is what makes the difference."

"I track VO2 max obsessively. Vitanzo was the first app to flag that my trend had been flattening for three months before I noticed it myself — and it gave me a specific reason why based on my recovery data."

Connects to your stack. Adds what's missing.

Vitanzo pulls from the platforms you already rely on — no manual entry, no new sensors, no switching apps.

Built by someone who needed it

Why I built Vitanzo

I'd been tracking my health obsessively for years — Oura, Apple Watch, continuous glucose monitors — and still had no idea what to actually do differently each day. The data was there. The direction wasn't. Vitanzo is the tool I wished existed: one clear answer every morning, built from everything I was already measuring.

Common questions

Does Vitanzo work without an Apple Watch?

Yes. Vitanzo works with iPhone only using data from Apple Health, which aggregates readings from your iPhone's motion sensors and any connected apps. An Apple Watch adds richer data — particularly continuous HRV, blood oxygen, and sleep stage detail — but is not required to get started.

What about Android?

Vitanzo is iOS only for now. Android is on our roadmap but there's no confirmed timeline yet. Our core architecture relies on Apple Health and on-device Apple frameworks, so a proper Android version isn't a quick port — we want to do it right.

How does the Whoop integration work?

Whoop exports your recovery, strain, and sleep data to Apple Health via the Whoop app. Vitanzo reads this data directly from Apple Health — no separate Whoop account connection required. As long as Whoop's Apple Health sync is enabled in your settings, it just works.

Is Vitanzo free?

Vitanzo is completely free during the beta period. No credit card is required to join. Pricing for the full release will be announced closer to launch — beta testers will be the first to hear about it.

What happens to my data if Vitanzo shuts down?

Nothing is lost. All your health data is stored locally on your device within Apple Health — Vitanzo reads it but never copies it to our servers. If Vitanzo ceased to exist, your data would remain fully intact and accessible through Apple Health and any other apps you use. There is nothing to delete from our end.
