In the Wyze app, tap your Wyze Scale, open Scale Settings, tap Authorize 3rd-Party Apps, choose Apple Health, and tap Authorize. Wyze says measurements can then sync automatically. Wyze doesn't publish which of the scale's 12 metrics reach Health; count on weight and body fat percentage, and treat the rest as app-only until verified.
Trendline is an iPhone app that reads Apple Health. This page covers getting Wyze readings into Health; why Health is the right destination at all is its own page.
How to turn the sync on
Wyze's support article opens with the claim that your measurements "can sync automatically to Apple Health" once you authorize it (Wyze support: How do I sync the Wyze app with Apple Health?, read October 18, 2026). The vendor's path:
In the Wyze app, tap your Wyze Scale.
Tap the gear to open Scale Settings.
Tap Authorize 3rd-Party Apps, then Apple Health.
Tap Authorize and follow the on-screen instructions.
iOS then shows the standard Health permission sheet; grant the categories you want written. "Automatic" is Wyze's word for what happens after authorization — the vendor's documentation doesn't spell out whether the app must be open at weigh-in, so this page won't claim it either way.
Twelve metrics on the scale, far fewer in Health
Wyze's measurement article lists 12 body-composition metrics the scale estimates: weight, body fat %, heart rate, muscle mass, BMI, body water %, lean body mass, bone mass, protein %, visceral fat, basal metabolic rate, and metabolic age (Wyze support: What can my Wyze Scale measure?, read October 18, 2026). Here's the honest boundary: Apple Health simply has no data type for most of that list. Protein %, visceral fat, body water %, bone mass, BMR, and metabolic age cannot land in Health no matter what any app does — they stay in the Wyze app.
Which of the 12 actually write to Health? Wyze's sync article doesn't publish a list. The Wyze app's own App Store copy names "weight, body fat percentage, water percentage, and more" as syncing with Apple Health (The Official Wyze App on the App Store, checked October 18, 2026) — and note that even that short list overreaches, because Health has no body-water type for a water percentage to land in. Treat weight and body fat % as the types you can count on, verify the rest in your own Health app under Browse → Body Measurements, and treat everything Health can't store as app-only.
Which model do you have?
Wyze has shipped several scales, including the original Wyze Scale, Scale S, Scale X, Scale Ultra, Scale Ultra BodyScan, and Scale BodyScan. This article is written against Wyze's general scale documentation (the sync and measurement articles above sit in the base Wyze Scale FAQ); per-model details, including the exact metric list, can vary. The Ultra in particular has its own history with Apple Health: an owner thread from November 2024 reports Ultra weigh-ins failing to reach Health, followed within days by a Wyze app update whose release note said it fixed a bug causing the Apple Health sync failure (Wyze forums: Wyze Scale Ultra — Apple Health issues). If your readings stop arriving, checking for a Wyze app update is a documented first move.
One thing Wyze does not document anywhere we can find: whether enabling the sync backfills readings taken before you authorized it. Assume it doesn't — treat authorization day as day one, and add older weigh-ins to Health by hand if you want them in the record.
Wyze scale not syncing to Apple Health?
Wyze's Apple Health article covers setup only. Its troubleshooting articles are written for specific models: the Scale Ultra, the Scale Ultra BodyScan, and (in a separate article, Wyze: Scale BodyScan integrations troubleshooting) the Scale BodyScan. The first two groups of steps below come from those; on other models, treat them as reasonable checks rather than documented fixes.
- Make sure the reading reached the Wyze app. For the Scale Ultra, Wyze's checklist is: update the app and the scale firmware, allow Bluetooth and Location for the Wyze app (with Precise Location on iPhone), step on and wait for the scale to read 0.0 again, confirm it shows Connected, claim any unclaimed data, check the right user profile is selected, and make sure "Only Measure with App Open" isn't turned on. Removing the batteries for 10 seconds comes next (Wyze: Scale Ultra not syncing while the app is closed).
- Re-authorize Apple Health. In the scale's settings, open Authorize 3rd-Party Apps, choose Apple Health, unauthorize it, authorize it again, and take another measurement (Wyze: Scale Ultra BodyScan integrations troubleshooting; the Scale BodyScan article gives the same unauthorize-and-re-enable steps).
- Check Health's side. In the Health app, tap your profile picture, then Apps, then Wyze, and check the categories you want are allowed. If another app also writes weight, open Health's Weight category, then Data Sources & Access, and check the order Apple uses to prioritize them (Apple Support).
Getting your data out
Wyze answers the export question directly, and the answer is yes: in the Wyze app, tap your Scale → Settings gear → Export Data, pick a range (week, month, year, or custom), and export (Wyze support: Can I export my Wyze Scale data?, read October 18, 2026; the article shows "Updated June 22, 2026"). The same article says you may also be able to export from Apple Health itself. Apple's Health guide says Health data stays on your iPhone and is under your control, so once readings are written there they are not held only inside one vendor's app.
What lands where
| What the Wyze app writes to Apple Health | What Apple Health can store | What Trendline reads from Health |
|---|---|---|
| Not published by the vendor as an exact list. The App Store copy names weight and body fat % (plus "water percentage", which Health has no type for). Vendor-claimed types: weight, body fat %; confirm the resulting samples in your own Health app (App Store listing, October 18, 2026). | 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 manual entries for the composition values Apple Health has no type for — the body water, protein, and visceral fat numbers that currently live only in the Wyze app.
Try the idea
Once your weigh-ins are flowing into Health, the raw series will wander day to day — that's variation, not a malfunctioning scale. 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
How do I connect my Wyze Scale to Apple Health?
In the Wyze app, tap your Wyze Scale, tap the gear to open Scale Settings, tap Authorize 3rd-Party Apps, then Apple Health, then tap Authorize and follow the on-screen instructions. iOS then shows the standard Health permission sheet.
Which Wyze Scale measurements sync to Apple Health?
Wyze's sync article doesn't publish a list. The App Store copy for The Official Wyze App names "weight, body fat percentage, water percentage, and more", but Health has no body-water type. Treat weight and body fat % as the types you can count on, and verify the rest under Browse, Body Measurements.
Why isn't my Wyze Scale Ultra syncing to Apple Health?
An owner thread from November 2024 reports Ultra weigh-ins failing to reach Health, followed within days by a Wyze app update whose release note said it fixed a bug causing the Apple Health sync failure. Checking for a Wyze app update is a documented first move (Wyze forums).
Will my old Wyze readings sync to Apple Health?
Wyze does not document, anywhere we can find, whether enabling the sync backfills readings taken before you authorized it. Assume it doesn't, and add older weigh-ins to Health by hand if you want them in the record.
Can I export my Wyze Scale data?
Yes. In the Wyze app, tap your Scale, the Settings gear, then Export Data, pick a range (week, month, year, or custom), and export (Wyze support: Can I export my Wyze Scale data?).
