I think data should be able to be both written and read to/from Apple HealthKit. Steps and other data in particular. You read data from say Zwift while I am not using a Garmin device, so why not pull data from HealthKit? Steps and sleep would be nice. You eventually have to take off the Fenix to charge the thing, so why not count the steps that say my iPhone count while I’m not wearing my watch? Should be a quick software update to connect.
