The new Health Data AI Assistant turns your Apple Health history into clear, private answers. Ask about your latest VO₂max, why HRV dipped, or how sleep changed this week—the assistant responds in plain language using models that run entirely on your iPhone. No servers, no uploads, and you choose the model size that fits your device.

Two packages you control

Choose between the Recommended package (~2GB) for fast responses on any device, or the Advanced package (~5GB) for more detailed answers on iPhone 15 Pro and newer. The app auto-detects device compatibility and guides you to the right choice. Downloads happen once, stay on your device, and can be removed anytime from Settings to reclaim space.

Questions the AI can answer

"What's my current VO₂max?" — gets the latest reading and trend context.
"Why did my HRV drop?" — ties dips to sleep, strain, or recovery patterns.
"What changed this week?" — summarizes Monday–Sunday shifts in one reply.
"How can I improve sleep?" — offers suggestions grounded in your data, not generic tips.

Built for privacy and control

All processing stays on your iPhone. Conversations are never sent to the cloud, and the assistant respects your Health permissions—if you disable a metric, it simply omits it. You can switch models or remove them entirely with one tap when you want to free space.

How to start

Update to the latest My Bio Age release.
Tap the AI Chat button on your dashboard.
Choose Recommended or Advanced (the app checks device compatibility), download over Wi‑Fi, and start asking questions.
Revisit Settings anytime to swap packages, clear downloads, or adjust Health permissions for tighter control.

The Health Data AI Assistant is live now. Try it the next time you wonder why a metric moved, and get answers grounded in your actual health history—without sacrificing privacy.
