I use the iOS Companion App in conjunction with the AppleTV to do my Zwift Training. I absolutely love it!
However, I am struggling to get the data from my rides to my Apple Health, which acts as the hub for integration with a host of other health and training related apps. Right now I am forced to use the crap program Strava to send my Zwift data to Apple Health. The reason I say crap is that the majority of the data is kept in Strava and not sent to Apple Health. E.g. HeartRate data.
The iOS Zwift App is perfectly capable of sending the required data from a workout to Apple Health and it would be awesome if those features could be programmed into the iOS Companion App.
