Amazfit documents almost nothing about Apple Health for its scale. The Amazfit Smart Scale's user guide does not mention Apple Health, and no official document we could locate says which scale measurements the Zepp app writes to it. This guide separates a small documented core from community walkthroughs and plain unknowns.
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
Every brand page on our smart-scale index works from vendor documentation first. Amazfit gives us almost none to work from. On July 20, 2026, and again on October 18, 2026, the entire official support offering for the Amazfit Smart Scale was two items — a user guide and an EU declaration of conformity (Amazfit support) — and the user guide does not mention Apple Health once. The Zepp app's App Store listing (version 10.9.1 when we re-read it on October 18, 2026) doesn't mention Apple Health, HealthKit, or scales anywhere in its description either; its only use of the word "weight" is in meal logging, not body weight. Even Etekcity, our previous thinnest paper trail, at least prints "Apple Health" on a product page. So this page is mostly an exercise in labeling: a small documented core, a community-documented layer, and a set of plain unknowns we refuse to fill with guesses.
Which app? Zepp vs. Zepp Life
Two similarly named apps, both from Zepp Inc., serve different hardware families — the same naming trap our Xiaomi page untangles from the other side:
- Zepp (App Store) — "the official app for Amazfit," per its own listing. This is the app the Amazfit Smart Scale's user guide points at — its setup instruction is to open the Zepp app, register or sign in with an account, and pair the scale following the on-screen prompts (user guide). If your scale says Amazfit, you're here — and note the vendor's own instructions assume a Zepp account.
- Zepp Life (formerly Mi Fit; App Store) — the Xiaomi-lineage app, which lists the Mi Body Composition Scale and Mi Scale among its devices and states, in its listing's own words, "This App version supports using Apple Healthkit within app." If your scale says Mi or Xiaomi, that page is your path, not this one.
The confusion is understandable — one developer, two ecosystems, one shared word in the names. Checking which app your manual actually names is worth doing before any troubleshooting.
What Amazfit does document
The scale itself is reasonably specified: the user guide's symbol legend covers weight plus body fat rate, muscle mass, body water percentage, protein percentage, bone mass, visceral fat grade, basal metabolism, subcutaneous fat, skeletal muscle, BMI, physical age, and heart rate — a dozen-plus readouts, most with no Apple Health type. What's specified stops at the Zepp app's front door. The official sentences we could find connecting the Zepp app to Apple Health sit in smartwatch material: a support article, which says: "For Apple Health/Google Fit, please add Zepp app as the data source in them" (Amazfit GTS 2 Mini support doc), and a Japanese Zepp guide page that lists Apple Health among the phone apps Zepp links to (Amazfit Japan). Neither is a scale spec — and no official Amazfit or Zepp document we could locate says which scale measurements, if any, the Zepp app writes to Apple Health. We looked; we're telling you the search came up empty rather than papering over it.
Turning the sync on
Here's the portion that's verifiable, tier by tier:
- OS-level (solid): if Zepp requests Health access, iOS shows the standard permission sheet listing each data type the app wants to write — that sheet, whenever it appears, is the most authoritative type list you'll get. The switches afterward live in Apple Health: profile icon → Apps → Zepp (Apple's guide).
- Community-documented (label it as such): third-party walkthroughs put the in-app connection under the Zepp profile tab's accounts section — StepsApp's guide gives it as Profile → Add accounts → Health; the label may differ by app version. None of this is vendor specification, and all of it was written about watch and step data.
- Undocumented: whether enabling that connection carries scale readings — and which of them — is stated nowhere official we can cite. Of the scale's readouts, only weight, BMI, body fat rate, and heart rate have Apple Health types to land in; the rest have no type at all, and Zepp does not document which of the types it writes.
What lands where
| What Zepp writes to Apple Health | What Apple Health can store | What Trendline reads from Health |
|---|---|---|
| Undocumented for scale data. The Zepp listing makes no HealthKit statement, and no vendor doc enumerates data types; the official Apple Health sentences cover watches (support doc). Of the scale's readouts, only weight, BMI, body fat rate, and heart rate have Health equivalents at all. | Weight, BMI, body fat %, lean body mass, height, waist circumference. Heart rate has its own type, but no body-composition types exist for muscle mass, body water, bone mass, protein, 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 (or unverifiable) sync needn't mean a thin record.
Amazfit scale not syncing to Apple Health?
With no vendor troubleshooting doc for the scale, the reliable sequence is the generic HealthKit one, cheapest step first:
- Check the reading exists in Zepp at all. If the weigh-in never left the scale, the problem is pairing, not Health — re-pair the scale in the Zepp app before touching permissions.
- Confirm the write permissions in Health → profile → Apps → Zepp, every category you care about switched on (Apple documents where these live; it does not say what a reinstall or iOS update does to them).
- If permissions look right, reconnecting the in-app Health connection from the profile tab's accounts section is a reasonable experiment. Neither Apple nor Amazfit documents it as a scale repair.
And the boundary no vendor states for you: readings flow from the day you enable the connection, forward. Nothing in Amazfit's or Zepp's documentation says whether past weigh-ins transfer to Apple Health when you first grant access — so we don't claim it either way. If your Zepp history predates the toggle, check Health after enabling rather than assuming.
Try the idea
Whatever your sync situation turns out to be, the trend question doesn't have to wait for it. Paste a few weeks of weigh-ins — from Zepp, 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 Amazfit scale sync to Apple Health?
No official Amazfit or Zepp document that we could locate says which scale measurements, if any, the Zepp app writes to Apple Health. The user guide does not mention Apple Health once, and the Zepp listing makes no HealthKit statement.
Which app does the Amazfit Smart Scale use?
Zepp, "the official app for Amazfit," per its own listing. Zepp Life (formerly Mi Fit) is a different app, the Xiaomi-lineage one for the Mi Body Composition Scale and Mi Scale.
How can I see which Amazfit scale measurements reach Apple Health?
If Zepp requests Health access, iOS shows the standard permission sheet listing each data type the app wants to write, and that sheet is the most authoritative type list you'll get. The switches afterward live in Apple Health under your profile icon, then Apps, then Zepp.
Why isn't my Amazfit scale syncing to Apple Health?
With no vendor troubleshooting doc, try the generic sequence, cheapest step first: check the reading exists in Zepp at all, confirm the write permissions in Health under your profile, Apps, Zepp. If those look right, reconnecting the in-app Health connection is a reasonable experiment, though neither Apple nor Amazfit documents it as a scale repair.
Will my past Amazfit readings transfer to Apple Health?
Nothing in Amazfit's or Zepp's documentation says whether past weigh-ins transfer to Apple Health when you first grant access. Check Health after enabling rather than assuming.
