Perfect!

This is exactly what I was looking for to sync Garmin HRV data to my Apple health. Works smoothly. Just need to sync daily for HRV data and it won’t double sync if accidentally synced twice. Now need one for SPO2 data. I do recommend this!

Delightful, and it works

Super nice little app with complete privacy. Solved my HRV sync issue between Garmin Connect and Apple Health. I tried other apps but either they didn't support Garmin Connect, or they charged a monthly fee and took possession of my data.

(Now I'm just looking for an app to sync VO2 Max and respiration...)
