GOOD TO KNOW
Before you get started.
- Devices and requirements
- iPhone requires iOS 17+; Apple Watch requires watchOS 11+. Read access to Apple Health is optional and user-controlled; results depend on available records.
- Interface language
- English / Simplified Chinese
- Records and privacy
- Health analysis and cached results stay on your devices. Health data is not uploaded to developer servers. Apple Health access is read-only.
- Practical limits
- For understanding your records, not medical diagnosis, treatment, medication or emergency decisions.
