- iPhone users who want read-only health data to automate check-ins
Check-in examples
What can count as a check-in.
- Check in a walking habit when Apple Health reports enough steps for the day.
- Complete a sleep habit when the longest non-nap sleep session reaches the target.
- Let HealthKit check the habit in without entering the same number again in Main Character.
How it works
From source signal to habit check-in.
- 01
Connect Apple Health from the Main Character iPhone app and approve read-only access to steps and sleep.
- 02
Choose steps or sleep duration as the automatic check-in method for a recurring habit.
- 03
The iPhone app reads the selected HealthKit metric and sends only the data Main Character needs for the check-in.
- 04
Main Character checks the habit in when the daily target is met, while manual check-ins remain available.
Privacy boundaries
Your data stays scoped.
- Apple Health access is read-only and available only in the native iPhone app.
- Main Character requests steps and sleep access for supported automatic check-ins; it does not write data to Apple Health.
- Imported summaries, sync jobs, automatic check-in settings, and separate supporting data for automatic check-ins are deleted when Apple Health is disconnected in Main Character. Existing check-ins, including their health-source references, remain in your history.
FAQ
Common questions.
Does Main Character write data to Apple Health?
No. The integration requests read-only access to supported HealthKit data and does not write health data back to Apple Health.
Can I still check in manually?
Yes. Manual check-ins remain available when Apple Health data is delayed, unavailable, or not the right fit for that habit.
