Apple Health/Fitness

I have Saris H3 and run Zwift on a PC with a Garmin heart rate monitor. Frustrating that Zwift talks to Strava but not Apple. I purchased the HealthFit app as someone suggested that it would upload to Apple. It does not, rather it mirrors Apple health.

I do have an Apple Watch Ultra but would rather not be dealing with duplicate data, and ensuring the watch always has enough juice to monitor the ride.

Looking for a solution (preferably free and automated) to upload the data including wattage to Apple Health and close fitness rings etc. It shouldn’t be this complicated with today’s tech.

TIA
