What data does Cadence sync to Apple Health?
As of version 1.7.17, Cadence syncs all workout data to Apple Health, including workout type, location, duration, distance, elevation, speed, steps, and calories.
When synced to Apple Health, these workouts will contribute to your Activity Rings in the Fitness app.
Make sure to turn on access in the main Settings app › Health › Data Access & Devices › Cadence.
