Why It Matters

Stop   guessing. Start   understanding.

Apple Health collects everything — steps, heart rate, sleep, workouts, HRV. But it never tells you what it means. We connect your data to AI and translate it into insights you can actually act on.

Ask Anything

Why is my resting heart rate higher this week? Am I sleeping enough? Just ask and get clear, personalised answers based on your actual data.

All Your Metrics

Heart rate variability, VO₂ max, walking distance, exercise minutes, respiratory rate, sleep score, body fat, BMI — every metric Apple Health tracks, connected and explained.

Powered by AI

Bring your own AI key or use our fully managed solution. Either way, your health data gets the intelligence it deserves — without compromising your privacy.

Privacy

Your   data. Your   device. Your   rules.

We don’t store your health data on our servers. We can’t see it. We can’t sell it. The app reads from Apple HealthKit directly on your device, processes insights locally or through your own AI key, and keeps everything between you and your iPhone. That’s it.

On-Device Processing

Your raw data never leaves your iPhone.

02

BYOK or Managed

Use your own key for total control, or trust our managed infra.

03

No Data Selling. Ever.

We have zero access to your health metrics. We literally can’t sell what we don’t have.
