Apple Health AI Assistant: Guided Questions, On-Device Answers
Explore My Bio Age’s private AI Coach for Apple Health metrics, with guided questions, optional local models and no health-data upload for answers.
By My Bio Age
The AI Coach in My Bio Age helps you explore measurements already available to the app. You select a question rather than type an open-ended prompt. Answers use local health facts and run on your iPhone, so your health history is not uploaded to a chatbot service.
Start with a question type
- Status gives a current summary for a selected metric.
- Why explores available context around a metric’s change.
- Improve offers general wellness suggestions associated with that metric.
- Weekly Summary compares the last two complete Monday-to-Sunday weeks.
For example, select HRV and a Why question to review the available context, or choose Sleep and Status for a current overview. The app cannot establish a medical cause for a change. Its interface has no free-text chat, conversational memory or streamed conversation.
What “grounded in your data” means
The app builds summaries and facts from the Health records and scores it can access. It retrieves a relevant selection for an answer. Longer-term summaries can include older available records in versions with extended history. The Index stays within six months; the model does not inspect every raw sample or know unrecorded details about your day.
If an answer seems inconsistent, return to the chart and check its dates, units and missing values. Generative models can produce mistakes even when facts are supplied.
Model options and device requirements
Qwen3.5 2B is the Recommended option; Qwen3.5 4B is the Advanced option for devices with more memory. Use the app’s current download screen for package sizes and device guidance. The app also uses a local embedding model to help retrieve relevant facts.
Downloading those model files needs a network connection and storage space. They are downloaded only when you choose to install them. Without a language model, template-based responses remain available. You can remove downloaded models through the app’s settings.
What stays private
The Index, health facts and AI answer generation are processed locally. Model file downloads are separate from health-data inference. If you choose to share an image or send a support email, only the information you select is included in that action.
The AI Coach provides general wellness information, not medical advice. It cannot diagnose, prescribe or replace professional interpretation of symptoms.
