| Comparison | In one line | Updated |
|---|---|---|
| Apple Health for AI: JSON vs CSV vs XML | XML vs CSV vs JSON for feeding Apple Health data to AI, compared on LLM-readability, schema, size, tooling and privacy, and why clean JSON over MCP wins. | 27 Jun 2026 |

The short version
- MetricBridge does: answer your questions about Apple Health on your iPhone with the numbers behind each answer, export 194 metrics as JSON, PDF reports, and an open source MCP server for your own agents. One purchase, no subscription.
- MetricBridge does not: score your recovery, run on Apple Watch or Mac as an app, log food or workouts, or send a question to a cloud AI.
