Your health data, finally understood
Vita pairs with Apple Intelligence to read the signals your body sends every day -- and turns them into coaching that's genuinely personal. All on your iPhone. Nothing ever leaves.

Three steps. Zero data leaves your phone.
Your body tells a story
Every night, your Apple Watch quietly captures the signals that matter -- HRV, resting heart rate, sleep stages, VO2Max, and more. Vita collects them all from HealthKit, and none of it ever leaves your iPhone.
Intelligence meets intuition
Apple Intelligence reads between the lines of your data. Running entirely on your iPhone's Neural Engine, it spots patterns you'd never notice -- connecting last night's sleep to today's readiness to this week's training load.
Coaching that knows you
No generic tips. No one-size-fits-all advice. You get narratives written for your body, your patterns, your goals -- like having a coach who's studied every workout you've ever done.

Insights that feel like they were written by your coach
Workout Analysis
Every session has a story
You just finished a hard run. Was it too much? Right on target? Apple Intelligence knows -- because it sees the full picture. Your current readiness, your recent training load, how this session stacks against your chronic baseline. In seconds, you get a narrative that puts today's effort in context.
- How hard you actually worked, relative to your baseline
- What this means for tomorrow's recovery
- Where this session fits in your training arc
- Whether your timing was optimal
Body Age Narrative
The age your body actually feels
Your chronological age is just a number. Your Body Age -- calculated from VO2Max, HRV, resting heart rate, and body composition -- tells the real story. Apple Intelligence weaves these signals into a narrative that explains where you stand, what's driving it, and how your training is shifting the needle.
- Plain-language explanation of your biological age
- The specific factors pulling your age up or down
- How your trends are shifting over weeks and months
- What to focus on next
Privacy First
Private by architecture, not just by promise
Most AI needs your data to go somewhere. Apple Intelligence doesn't. Everything runs directly on your iPhone through Apple's FoundationModels framework. We didn't build privacy as a feature -- we built an app where your data physically cannot leave.
Runs on your Neural Engine
Every AI inference happens locally on your iPhone. No cloud round-trips. No waiting. Instant.
No servers to breach
We don't operate servers that touch health data. You can't leak what you never collect.
No account. No sign-up. No trace.
Open the app and go. No email, no profile, no login screen standing between you and your data.
Apple's rules, always
Every data point flows through Apple's HealthKit APIs. You choose exactly what to share -- and can revoke it anytime.
Under the Hood
Deep integration with every Apple framework that matters
Structured AI with FoundationModels
Vita uses Apple's FoundationModels framework with @Generable structured output -- meaning the AI produces typed, predictable responses that map directly to the UI. No fragile text parsing. No hallucination risk in critical health data. Just clean, reliable insights every time.
10+ health signals, one coherent picture
Heart rate variability, resting heart rate, sleep stages, VO2Max, body composition, workout history, training load ratios, wrist temperature, respiratory rate, oxygen saturation -- and more. The AI doesn't see isolated numbers. It sees the relationships between them, the way a coach would.
It learns what's normal for you
Over 14-30 days, Vita builds a personal baseline -- your sleep rhythm, your recovery curve, your training response. The AI uses your normal as the reference point, not population averages. A 55ms HRV means something different for you than for someone else.
Native to the Apple ecosystem
Your body has something to tell you
Start listening. Apple Intelligence and Vita turn the health data you're already collecting into coaching that's actually worth reading.
