Health Sync: Google to Apple

Steps, active energy, walking & running distance, heart rate, resting heart rate, heart rate variability, body mass, body fat percentage, flights climbed, water, blood glucose, body temperature, VO₂ max, blood oxygen, respiratory rate, height, and sleep.

Make sure the app is allowed to write to Apple Health: open Settings → Apps → Health → Data Access & Devices, select this app, and turn on the data types you want. Then run the import again — re-importing never creates duplicates.

The app requests read-only access to your Google health data. If you declined a permission during sign-in, the affected data types can't be imported — sign out from the app's settings, sign in again, and accept all requested permissions. If your session has expired, signing out and back in also fixes it.

When you enable Automatic Sync, iOS runs the app in the background roughly once a day and imports anything new since the last sync, with a notification on completion. A few things to know:

• iOS decides the exact moment; timing varies with your usage and battery.
• Keep Background App Refresh enabled in Settings.
• Don't force-quit the app from the app switcher — that stops iOS from waking it.

No. The import happens entirely on your device: the app reads from Google's API and writes straight into Apple Health. There is no server of ours in between, no account to create, and no analytics on your health values.

Open the Apple Health app, go to Browse, pick a data type, tap Show All Data, and delete entries from this app. Deleting the app also lets you remove all of its data when iOS asks.
