Vitals Sync imports four metrics your Garmin records but does not send to the Health app: HRV, Respiration, SpO₂, and VO₂ Max. Everything runs on your device. You sign in with your Garmin Connect account. The app reads the data your Garmin watch already recorded and writes it to the Health app on your iPhone. Most syncing tools cover only HRV. Vitals Sync does all four. WHAT YOU NEED • A Garmin Connect account • A Garmin watch that records these metrics, like the Forerunner, Fenix, Venu, vívoactive, Instinct, Epix, or Enduro series, and more WHAT IT SYNCS • Heart Rate Variability (HRV) • Respiration rate • Blood oxygen (SpO₂) • VO₂ Max FEATURES • Automatic background sync • No duplicates. Every reading is written once. • Your password is not stored. Only secure tokens, kept in the iOS Keychain on your device. • No account for this app, no tracking, no analytics, no servers PRIVACY Vitals Sync has no backend. It talks directly from your iPhone to your own Garmin account and to the Health app. We never see, collect, or store your data. Vitals Sync is an independent product and is not affiliated with, endorsed by, or sponsored by Garmin Ltd. or its subsidiaries, or by Apple Inc. Garmin® is a registered trademark of Garmin Ltd.

ReceptionRating · Positive reviews · Number of ratings

Vitals Sync holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Vitals Sync has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of LinkLoop T1D's written reviews are positive against 50% of Vitals Sync's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
