Etekcity publishes little about Apple Health. Its ESF-551 page says the scale works with the free VeSync app and syncs data with Apple Health, the VeSync App Store listing confirms HealthKit, and a public Etekcity VeSync guide (October 8, 2026) gives the menu path, but we found no official list of data types.
Trendline is an iPhone app that reads Apple Health. Everything below assumes an iPhone; the destination for your readings is Apple Health, which Android does not run.
What this page can and can't promise
Etekcity now publishes a public VeSync guide, dated October 8, 2026, that gives the menu path for connecting Apple Health (Etekcity's VeSync scale guide). It is written for one model, the EFS-A791-KUS, and it does not list the data types VeSync writes. So this page works from three honest tiers: what Etekcity's product pages state, what the VeSync app's own App Store listing states, and what owners report. Where a fact lives in the third tier, we say so — a guess dressed as documentation would be worse than the gap.
What Etekcity does state
The product pages are clear about compatibility, if not mechanics. The ESF-551 page says the scale works with the free VeSync app and "syncs data with popular fitness apps like Apple Health," alongside Google Fit, Samsung Health, Fitbit, and MyFitnessPal. The VeSync App Store listing confirms the HealthKit connection from the app side — VeSync can feed health and wellness data into Apple Health — without enumerating which measurements. So the pipeline is vendor-confirmed: scale → VeSync app → Apple Health. Etekcity's guide adds that the scale does not connect directly to third-party apps: measurements are synced through VeSync before they are shared with supported services. The fine print, meaning which measurements are written, is still not published.
Which app? (VeSync vs. VeSync Fit)
Current Etekcity products point at VeSync — one app for the whole Etekcity/Levoit/Cosori family, scales included. But older Etekcity scale manuals reference a separate VeSyncFit app: the ESF24 manual's Apple Health section, for example, walks through enabling categories for "VeSyncFit" from inside Apple Health (ESF24 manual, p.18). The App Store today resolves searches for VeSync Fit to the unified VeSync app. If a printed manual in your scale's box names VeSyncFit, treat it as the older generation of the same path — install VeSync, and expect the manual's screenshots to be out of date.
Turning the sync on
Here is the portion that's vendor-documented and OS-level verifiable:
- When VeSync first requests Health access, iOS presents the standard permission sheet listing each data type the app wants to write. Grant the categories you want.
- If that moment has passed, the switches live in Apple Health: tap your profile picture or initials, then Apps under Privacy, and select VeSync (Apple's guide).
- Inside VeSync, Etekcity's guide says to open the scale's Dashboard page, scroll down, tap Third Party Services, select Apple Health, and follow the on-screen instructions (Etekcity's VeSync scale guide).
What owners report, labeled as such: one review on the VeSync listing says body fat percentage and BMI transferred to Health from an old phone, but nothing, not even weight, transferred from a new phone with all permissions allowed; the reviewer had only heard that uninstalling and reinstalling might help and had not tried it. Etekcity does not publicly document any of this; treat it as field experience, not specification.
What lands where
| What VeSync writes to Apple Health | What Apple Health can store | What Trendline reads from Health |
|---|---|---|
| Vendor-confirmed only in general terms: product pages state Apple Health syncing (ESF-551), and the App Store listing confirms HealthKit. We found no official list of data types; one owner review mentions body fat % and BMI transferring from an older phone. The scale's other readouts (body water, bone mass, visceral fat) have no Apple Health type regardless. | Weight, BMI, body fat %, lean body mass, height, waist circumference. No types exist for body water, bone mass, or visceral fat. | Weight, body fat %, and lean body mass (height as context). BMI and waist are not imported — BMI is derivable, and neither carries trend information Trendline needs. |
Trendline also accepts manual entries — including composition values Apple Health has no type for, like visceral fat and body water — so a thin sync needn't mean a thin record.
Etekcity scale not syncing to Apple Health?
Etekcity's guide does not cover Apple Health failures, so the sequence below is the generic HealthKit one, cheapest step first:
- Check the reading exists in VeSync at all. If it does not, work on the scale-to-VeSync connection first; Etekcity says a measurement taken while the scale is not connected is stored on the scale and uploads once the scale reconnects to VeSync with an active internet connection (Etekcity's VeSync scale guide).
- Check the write permissions in Health: profile picture or initials → Apps → VeSync, every category you care about switched on, particularly after reinstalling the app or changing phones. Apple documents where these switches live; we found no source that says a reinstall or update silently resets them.
And the boundary no vendor states for you: Etekcity does not document whether past readings transfer to Apple Health when you first grant access, so we don't claim it either way. If your VeSync history predates the toggle, check Health after enabling rather than assuming.
Try the idea
Whatever your sync situation, the trend question doesn't have to wait for it. Paste a few weeks of weigh-ins — from VeSync, from Health, or from a notebook — into the free weight trend calculator. It runs in your browser, nothing uploads, and it draws a deliberately slower signal next to your raw measurements. Daily numbers vary for reasons that have nothing to do with progress; the slower line is the readable one.
Questions people ask
Does the Etekcity scale work with Apple Health?
Etekcity's ESF-551 page says the scale works with the free VeSync app and "syncs data with popular fitness apps like Apple Health." The VeSync App Store listing confirms the HealthKit connection from the app side, without enumerating which measurements.
Which Etekcity app do I need, VeSync or VeSync Fit?
Current Etekcity products point at VeSync. If a printed manual names VeSyncFit, treat it as the older generation of the same path: install VeSync, and expect the manual's screenshots to be out of date.
What does Etekcity write to Apple Health?
We found no official list of data types. One owner review mentions body fat % and BMI transferring from an older phone. The scale's other readouts, body water, bone mass, and visceral fat, have no Apple Health type regardless.
Why did my Etekcity scale stop syncing to Apple Health?
First check that the reading exists in VeSync; Etekcity says measurements taken while the scale is disconnected are stored on the scale and upload after it reconnects to VeSync. Then check the write permissions in Health (profile picture or initials, Apps, VeSync, every category switched on), particularly after reinstalling or changing phones. We found no source saying a reinstall silently resets them.
Will my past Etekcity readings transfer to Apple Health?
Etekcity does not document whether past readings transfer when you first grant access, so check Health after enabling rather than assuming.
