Only select Omron scales sync. Omron says OMRON connect syncs with its connected blood pressure monitors and select body composition monitors; its US page names the BCM-500 and SC-150, and a product page lists the BCM750. If yours is a connected model, link Apple Health: Profile, App settings, Share data with other apps, Apple Health, Link.
Trendline is an iPhone app that reads Apple Health. This page covers getting Omron weight readings into Health; why Health is the right destination at all is its own page.
Check your model before anything else
Omron's own app page states the scope plainly: the OMRON connect app "syncs with every one of our connected blood pressure monitors and select body composition monitors" (omronhealthcare.com/omron-connect-app, read October 18, 2026). Blood pressure is the product Omron builds its ecosystem around; weight is the sidecar. The US page shows the BCM-500 body-composition monitor and the SC-150 digital scale as OMRON Connect compatible, and Omron's product page for the VIVA 360+ BCM750 smart scale says it is compatible too (BCM750 page). Check your exact model on Omron's pages. If your Omron scale isn't a connected model, no app setting will produce an Apple Health sync — better to learn that in the first paragraph than deep in the settings.
How to turn it on
Omron's own support page gives the path (OMRON connect support on Omron Healthcare EMEA, read in a browser on October 18, 2026; Omron's US site does not publish the same steps as a separate page):
In OMRON connect, open Profile.
Tap App settings, then under Share data with other apps, tap Apple Health.
Tap Link, enable the categories you want to share, follow any on-screen instructions, then tap Allow or Done.
The integration is vendor-confirmed on both sides of the Atlantic: the App Store listing says the app can "Exchange readings directly with Apple Health" (OMRON connect on the App Store), and Omron's EMEA site lists connection with Apple Health among the app's free features (omron-healthcare.com/omronconnect, read October 18, 2026).
What the app shows that Health will not hold
The BCM-500 measures six metrics: body weight, body fat percentage, visceral fat level, skeletal muscle percentage, resting metabolism, and BMI (Omron's BCM-500 product page, read October 18, 2026). Of those, Apple Health has body-measurement types for weight, body fat %, and BMI. It has none for skeletal muscle percentage or visceral fat level (Apple's HealthKit type list). Omron's own lists of what OMRON connect shares with Apple Health name weight and no other body-composition value (see the table below). So expect skeletal muscle %, visceral fat level, and resting metabolism to stay out of Health. The monitor itself also stores up to 120 readings, according to the same product page, so the app is not the only place the numbers appear. If those numbers matter to your tracking, record them yourself.
OMRON connect not syncing to Apple Health? The "Inactive" pattern
The documented Omron-and-Health complaint isn't exotic: it's the connection reporting itself dead or half-alive. Across live Apple Support Communities threads, owners describe OMRON connect showing as "Inactive" in Health's sources list, or missing from Health's privacy settings entirely, or collecting readings that never appear in Health (254490299, 256100682, 255715477, 255388194; the last of these has no resolution in the thread, and we re-read all four on October 18, 2026). Several of these owners use Omron blood pressure monitors rather than scales, but the Health link lives in the same app. The fixes below resolved the other three; they are owner-reported, not vendor specification.
Start with Omron's own step: its support page says OMRON connect can only share your data with Apple Health when Apple Health is enabled inside the app, under Profile, then App settings, then Share data with other apps, then Apple Health, then Link (Omron support). Then check Health's side: Health, your profile picture, Apps under Privacy, OMRON connect, and confirm the categories you want are on (Apple Support). If it's enabled and readings still don't arrive, these fixes come from owners rather than Omron:
- Enable Background Sync in the OMRON connect app. One owner reported that this setting kept the link "Inactive" despite a correct setup (254490299, December 2022).
- Open the Apple Health entry and grant the data types explicitly via Profile → App settings → Apple Health, tapping the entry itself to reach the page where you choose data. The owner in 256100682 (July 2025) said this step was odd and took a few attempts. Another owner in the same thread reported that the iPad version of the app showed no option to link Health, so do this on an iPhone.
- Full reinstall and re-pair: unpair the device, unlink Health, delete and reinstall OMRON connect, then re-link Health and re-pair the device. This worked for one iOS 17 owner after other steps failed (255715477, August 2024).
Whether enabling the link backfills readings taken before it existed is not documented by Omron. Check Health after linking, and add older readings to Health by hand if you want the record complete.
What lands where
| What OMRON connect writes to Apple Health | What Apple Health can store | What Trendline reads from Health |
|---|---|---|
| Omron's current EMEA support page lists blood pressure readings, activity, oxygen, temperature, weight, sleep, and EKG(BP) as data OMRON connect shares with Apple Health (Omron support, read October 18, 2026). An older Omron help desk article (dated 2022) lists blood pressure readings and weight (Omron help desk). Of the body-composition values, only weight appears in either list. The EMEA app page also mentions body fat as something the app records, but neither list names it as exported, so check Health after linking (EMEA app page). | Weight, body fat %, lean body mass, BMI, height, waist circumference | Weight, body fat %, lean body mass — with height as context. BMI and waist are not imported. |
Trendline also accepts clinic-scan reports that can hold composition values Apple Health has no type for, such as visceral fat level, skeletal muscle mass, and basal metabolic rate.
Try the idea
Once weight readings are landing in Health, expect the series to wander from weigh-in to weigh-in — that's variation, not a fault in the monitor. Paste a few weeks of readings into the free weight trend calculator and compare them against a deliberately slower signal; the direction underneath is the number worth watching.
Questions people ask
Does my Omron scale work with Apple Health?
Only select models. Omron says OMRON connect syncs with its connected blood pressure monitors and select body composition monitors. The US page shows the BCM-500 body-composition monitor and the SC-150 digital scale as compatible, and Omron's product page for the VIVA 360+ BCM750 says it is compatible too. Check your exact model on Omron's pages.
How do I link Apple Health in OMRON connect?
In OMRON connect, open Profile, tap App settings, then under Share data with other apps tap Apple Health. Tap Link, enable the categories you want to share, follow any on-screen instructions, then tap Allow or Done (Omron EMEA support page).
What does OMRON connect share with Apple Health?
Omron's current EMEA support page lists blood pressure readings, activity, oxygen, temperature, weight, sleep, and EKG(BP). Of the body-composition values, only weight appears. An older 2022 Omron help desk article lists blood pressure readings and weight. Apple Health has no body-measurement type for skeletal muscle % or visceral fat level.
Why does OMRON connect show Inactive in Apple Health?
Owners in Apple Support Communities threads describe this pattern. Omron says the app can only share data with Apple Health when Apple Health is enabled inside OMRON connect, so confirm the link first. The fixes below are owner-reported, not vendor specification: enable Background Sync in the OMRON connect app, grant the data types explicitly via Profile, App settings, Apple Health on an iPhone, and, as a last resort, unpair, unlink Health, reinstall, and re-link.
Will my earlier Omron readings transfer to Apple Health?
Omron does not document whether enabling the link backfills readings taken before it existed. Check Health after linking, and add older readings to Health by hand if you want the record complete.
