Health Sync & Export: Apple Health, Health Connect, and JSON
Updated May 2026
VitaCal does not have to live in a silo. Connect Apple Health on iOS or Health Connect on Android and VitaCal becomes part of your wider health picture, pulling in the sleep, heart rate, HRV, workouts, weight, and cycle data your phone and wearables already record. And whenever you want a copy of what you have tracked, you can export it all as a JSON file.
Sync With Apple Health and Health Connect
Any user can connect VitaCal to the health platform on their device, free:
- Apple Health on iOS
- Health Connect on Android
Once connected, VitaCal can read the metrics your devices capture, including:
- Sleep stages and total sleep
- Heart rate, plus resting and walking heart rate
- Heart rate variability (HRV)
- Workouts and activity
- Body measurements such as weight
- Menstrual cycle
This is what makes VitaCal more than a calorie tracker. With your sleep, recovery, training, and nutrition in one place, the Ask Vitacal AI coach can answer questions grounded in your real numbers, and you can connect Claude or another MCP client to query the same data.
Export Everything You Track as JSON
Your data is yours. Any VitaCal user can export their tracking data as a single JSON file, including:
- Your full food log
- Water intake
- Weight history
- Calorie and macro goals
- Favourite meals
Keep it as a backup, analyse it yourself, or take it elsewhere. The export is plain JSON, so it is easy to read and easy to move. JSON export is available to all users, not just Pro.
What Needs Pro
Connecting Apple Health or Health Connect and importing your sleep, heart rate, HRV, workouts, weight, and cycle is free, including running Sync Now and backfilling your history. Pro adds two things: automatic background sync, so your data stays up to date without opening the app, and sending your nutrition back out to Apple Health or Health Connect. JSON export of your own tracking data is available on every plan.
