Gemini + HealthKit
Heart rate, workouts, steps, sleep, blood oxygen, respiratory rate, and more. Gemini AI turns raw data into answers you understand.
What it can do
with Apple Health.
Automatic health tracking
Steps, heart rate, sleep duration, blood oxygen, respiratory rate, walking steadiness, cardio fitness — 127 metrics tracked continuously through Apple HealthKit. The Thing reads them all, so you can ask about any of them at any time. "How did I sleep last night?" "What's my resting heart rate trend this month?"
Conversational nutrition logging
Tell The Thing what you ate in plain language. "I had two eggs, toast with avocado, and a coffee." It calculates calories, protein, carbs, fat, and micronutrients — then writes it directly to HealthKit. No barcode scanning. No food database searching. Just talk.
Trend analysis and insights
The Thing doesn't just read numbers — it understands patterns. It notices when your sleep quality drops, when your resting heart rate increases, when you're less active than usual. It connects the dots between your nutrition, activity, and recovery to give you insights a fitness tracker can't.
Proactive health alerts
When something looks off, The Thing tells you. Unusually high heart rate during rest. Significant drop in sleep quality over a week. Calorie intake consistently below your goal. It speaks up when it matters, not with notification spam — with a thoughtful, contextual observation.
Works while locked
Health tracking runs in the background using a specialised HealthKit workout session. Your phone can be locked, in your pocket, on your nightstand. Data flows continuously. This is not a fitness app you need to remember to open — it's always on.
Comprehensive data export
Ask The Thing for a weekly or monthly health report and it generates a clean summary — steps, sleep, nutrition, vitals — that you can review or share with your doctor. Your health data, structured and understandable, whenever you need it.

Privacy & Security.
Your health data never leaves your device.
All HealthKit data is read and processed locally on your iPhone. It is never uploaded to our servers.
Dietary entries are written directly to HealthKit — stored in Apple's encrypted health database, not ours.
Health insights are generated on-device. Your medical data is never used for AI model training.
Apple HealthKit enforces granular permissions. You choose exactly which data types The Thing can access.
Revoking health access is instant — one toggle in Settings and all HealthKit permissions are removed.
