Suggestion : SportVitals app $6 bucks, seems pretty good!
I checked the app metrics, They are based on science and very similar to Garmin

This set up work great with Apple watch and Fitbit Air.
SportVitals app: $6
Health Sync app: $4 ( I think)
Have apple on afib mode ( More hrv readings)
Every Time you want to see metrics
- Open Google Health app let the data sync
- Open health sync and sync data ( just have heart rate checked or data get messy in apple health)
- Open SportVitals to see data and metrics
JUST WANTED TO SHARE THE INFO AS A USER OF THE APP , IF VIOLATE ANY RULES YOU CAN TAKE DOWN.
