OMRON and Google Health cannot write data to Apple Health on iOS 27

If Omron or Google Health (Fitbit) cannot write data to Apple Health, and the permission sheet does not appear, the permission cannot be granted from the Apple Health app alone.

The important point is that the third-party app must first initiate the request to write data to Apple Health. The permission prompt is generated when the third-party app requests access. If the app has not implemented this functionality, or does not request permission, no permission sheet will appear in iOS.

Therefore, if Omron or Google Health (Fitbit) is not showing an option to allow writing data to Apple Health, you should contact the respective app developer and ask whether the app supports writing the required data types to Apple Health and whether the permission request is being initiated correctly.

For example, in the mySugr app, the permission to write data to Apple Health is initiated from within the mySugr app itself. This demonstrates that the third-party app has to request the required HealthKit permissions; it is not something that Apple Health can enable on behalf of an app.

Permission is required from both ends

For data sharing between Apple Health and a third-party app, the relationship can be viewed as requiring permissions in both directions:

1. Apple Health → Third-party app

The third-party app needs permission to read the relevant data from Apple Health.

See Picture 1.

2. Third-party app → Apple Health

The third-party app needs permission to write the relevant data into Apple Health.

See Picture 2.

These are separate permissions. Giving an app permission to read data from Apple Health does not automatically give it permission to write data to Apple Health, and vice versa.

So, if the Write permission does not appear at all, the issue is generally not something that can be fixed by changing a setting in Apple Health. The third-party app must support the relevant HealthKit data type and request the write permission.

In short, both sides have to be enabled, and the third-party app is responsible for requesting the appropriate permission. If that request is never made, iOS has no reason to display the permission sheet.

Fix that worked for me was triggering a walk in google health, ending it after 10 seconds, then deleting it. Everything then synced over, including sleep and activity.
