Get your smart scale's weigh-ins into Garmin Connect, straight from your iPhone. Two ways in, one tap out. APPLE HEALTH ROUTE: ANY SCALE If your scale's app saves weight to the Health app, Scale Relay picks it up and sends it to Garmin Connect. Works with Withings, Renpho, Eufy, Etekcity, Zepp Life, Wyze, Picooc and any other app that writes weight to Apple Health. Body fat and BMI come along when your scale's app provides them. BLUETOOTH ROUTE: XIAOMI SCALES, NO OTHER APP NEEDED Step on a Mi Body Composition Scale 2 or a Xiaomi Body Composition Scale S400 and Scale Relay reads the measurement directly: weight, body fat, muscle mass, bone mass, water, BMI and BMR. The S400 needs a one-time authorization with your Xiaomi account. WHAT YOU GET โข A preview of every weigh-in before it is sent; nothing leaves without your tap โข Body composition in Garmin Connect, not just the weight โข Weigh-ins from the last 7 days are included; Garmin Sync unlocks older history โข One Garmin sign-in, two-factor authentication supported โข A "Sent to Garmin" list so you know what arrived FREE TO TRY Your first two syncs are free on either route. Unlimited syncing is a single one-time purchase called Garmin Sync. No subscription. PRIVACY FIRST Your measurements stay on your iPhone and go only to your own Garmin account. No Scale Relay account, no tracking, no ads. REQUIREMENTS โข iOS 17 or later โข A Garmin Connect account โข Apple Health route: any scale app that writes weight to the Health app โข Bluetooth route: Mi Body Composition Scale 2 or Xiaomi Body Composition Scale S400 Scale Relay is an independent app. It is not affiliated with, endorsed by or associated with Garmin, Xiaomi, Withings, Renpho, Eufy, Etekcity, Zepp, Wyze, Picooc or any other scale or fitness-platform maker.

ScaleBridge allows you to synchronize measurements from your Beurer and Sanitas scales to Apple Health. No sign-up or cloud required. What it does - Works with Beurer BF700, BF710, BF800, and Sanitas scales that use the same protocol - Sends weight, body fat %, lean body mass, and BMI to Apple Health - Keeps water %, muscle %, bone mass, and impedance on the phone (Health doesn't have proper slots for those) - Reconnects and retries on its own when Bluetooth gets weird How to use 1. Open ScaleBridge 2. Step on your scale 3. Pull to sync 4. Done

Verdict
The clearest difference is in-app purchases: ScaleBridge at none against Scale Relay's 1. Scale Relay's advantage is update cadence (weekly vs every 3 weeks) and iOS requirement (17.0 vs 26.5). On price, ads and device support there is nothing between them.
