Data path

Fitbit / Pixel Watch

Google Health

No workout write-back to Apple Health

Zone Training Log

Set up the connection

Use Zone Training Log on Android with Health Connect for Fitbit, Pixel Watch, or Google Health workouts.
On iPhone, choose a recording source that officially writes workouts and detailed heart rate to Apple Health.

What to expect

Currently unavailable as a first-party iPhone route. The direction of the documented Apple Health integration is not suitable for feeding Zone Training Log.

Important limitations

Google documents Apple Health access as importing data into Google Health, not exporting Google Health workouts to Apple Health.
Zone Training Log does not connect directly to Fitbit or Google accounts.

Verify the data before opening Zone Training Log

In Apple Health, inspect Activity → Workouts and its data sources.
If Google Health or Fitbit is not writing the workout there, Zone Training Log cannot read it.

Troubleshooting

Changing Zone Training Log’s Health permission cannot create data that was never written to Apple Health.
Use the Android Health Connect route or another Apple Health-writing source.

Continue in Zone Training Log

Once the workout and heart-rate samples are visible, review the session in the Training Log and check its time-in-zone context.
