Set up Apple Health
HealthFactory reads what is in Apple Health. The better Health is set up, the more complete and accurate the analyses. Paths apply to iOS 26.
1. Let HealthFactory read everything
Health app → your profile picture (top right) → Apps → HealthFactory → Turn On All. Apple only shares medications individually: in HealthFactory under Settings (Choose medications …).
2. Let your devices and apps write to Health
Scale, blood pressure monitor, nutrition app, training and sleep apps must write their values to Health. You usually enable this in the respective app ("Apple Health" or "Health connection").
3. Order of data sources
If several devices write the same thing (e.g. steps from watch and iPhone), the order decides which value counts. Health → Browse → data type → Data Sources & Access → Edit → drag sources.
- Activity: Apple Watch before iPhone.
- Body measurements: the measuring device (scale) before apps where values are typed in.
- Nutrition: the app you actually log in at the top.
4. Sleep
With Apple Watch: wear it at night and set up a sleep schedule in Health under Browse → Sleep. Without a watch: a sleep app or device that writes to Health.
5. Keep the sync running
- iPhone Settings → General → Background App Refresh → HealthFactory on.
- Allow notifications: the app tells you when no data has arrived for a while.
- Don't swipe HealthFactory away in the app switcher: iOS no longer wakes swiped-away apps in the background.
- While the iPhone is locked, Health data is encrypted; the sync catches up after the next unlock.
