What Apple Health data reaches Gemini
Apple Health is the iPhone health-data hub, so the useful question is not whether the AI provider has an Apple Health integration. It does not. Wellness Project reads the HealthKit categories you authorize on-device, stores the supported history in your Wellness Project account, and exposes that structured history to the assistant.
That can include steps and activity, sleep, heart rate and resting heart rate, HRV, workouts, and body measurements when those records are present and you grant permission. Data from an Apple Watch or a third-party iPhone app only reaches the assistant if that source wrote it into Apple Health first.
Gemini does not receive a bulk wearable export. It asks Wellness Project for the supported rows needed for the question, through the authorized custom MCP app in Gemini Spark.
How to connect Apple Health to Gemini
Your setup screen may look different.
AI assistants change their settings and navigation frequently. Menu names and steps can vary by web, desktop, or mobile client, device and operating system, plan, account type, version, and staged rollout. Treat the instructions on this page as a current guide and look for the equivalent Apps, Connectors, Plugins, or MCP controls if your version differs.
Connect Apple Health in Wellness Project
Install Wellness Project on your iPhone, open Settings → Devices → Apple Health, and grant read permission for the categories you want to use. Apple Health access is on-device; the assistant never receives your Apple credentials.
Confirm the health history is present
Open Wellness Project and check that the recent steps, sleep, heart, workout, or body rows you expect have synced. If a source app never wrote a metric to Apple Health, Wellness Project cannot manufacture it.
Add Wellness Project as a custom app in Gemini Spark
Open gemini.google.com/spark, go to Settings → Personal intelligence → Connected apps → Add custom app, paste https://wellnessproject.ai/api/mcp, leave client credentials blank, and sign in to authorize Wellness Project.
Ask Gemini about your real history
Start with a bounded date range and a concrete question. For example: "Compare my sleep duration and resting heart rate over the last six weeks. What changed?" The assistant can then request the relevant Wellness Project rows instead of reasoning from a screenshot or one-off export.
What to ask Gemini once Apple Health is connected
The useful prompts compare your own history over time. These examples are shaped around the data this source actually sends to Wellness Project.
- Compare my sleep duration and resting heart rate over the last six weeks. What changed?
- Which weeks had the most consistent step count, and did my sleep look different during them?
- Show how my HRV trend moved around my hardest workout weeks.
Limits of the Apple Health → Wellness Project → Gemini path
Apple Health is permissioned category by category. A missing metric can mean the source app never wrote it, the category was not authorized, or the iPhone has not had a chance to sync it into Wellness Project yet.
The external assistant reads Wellness Project over MCP. It is not receiving a native Apple Health feed and it should not be treated as a medical-device interpretation of HealthKit data.
Gemini is reading an authorized Wellness Project MCP connection, not a native Apple Health integration supplied by Gemini's developer.
Connect Apple Health, then ask Gemini.
Sync the supported history into Wellness Project, authorize Gemini, and ask questions against your real trend instead of exporting files or pasting screenshots.
