Yes, as of October 2026, through Google Health. An Aria weigh-in still goes to your Fitbit account first, and the Google Health iPhone app (version 5.05 or later) can now write weight and body fat percentage into Apple Health. Google doesn't yet say whether past weigh-ins copy over or how fast new ones appear.
Trendline is an iPhone app that reads Apple Health. This page is date-stamped: everything below was checked on October 2, 2026. Its first version, from July, described the time before Google shipped the change covered here.
Can a Fitbit Aria sync to Apple Health? (as of October 2026: yes, through Google Health)
Yes, with one app in the middle. An Aria weigh-in still travels from the scale to your Fitbit account first; Google's help page for the Aria series describes that one step and doesn't mention Apple Health (Google's Fitbit scale help, checked October 2026). The new part happens after that: the Google Health app for iPhone can now write data into Apple Health.
Google added this in version 5.05 of the Google Health iOS app, released in early August 2026 (MacRumors, August 3, 2026). Google's own FAQ on using Apple Health with Google Health now includes a table of data types Google Health can write to Apple Health, and its body-measurement rows list weight and body fat percentage (Google Health Help Center, checked October 2026).
How to turn it on
- Update the Google Health app on your iPhone to version 5.05 or later. Google's FAQ lists iOS 16.4 or later and an adult Google Account as requirements.
- In Google Health, open Connections, then Apps and services, and add Apple Health (the path MacRumors reported at launch).
- When iOS shows the Health permission sheet, allow Google Health to write Weight and Body Fat Percentage.
- Step on the scale, let it sync to your Fitbit account, then open the Health app and look under Body Measurements for an entry from Google Health.
What Google doesn't say yet
- Your history. Neither Google's FAQ nor the launch coverage says whether weigh-ins from before you connect are copied into Apple Health. Check Health's weight chart after connecting rather than assuming years of Aria readings arrived.
- Timing. Google doesn't document how quickly a new weigh-in appears in Health. If one is missing, open the Google Health app; iOS limits how often apps sync in the background.
- Other measurements. Fitbit stores more than Google's write table lists. Lean body mass and BMI aren't in it, so expect only weight and body fat % to arrive.
The move from the Fitbit app to Google Health hasn't been smooth for everyone: some owners report weight history going missing in the forced migration (Google Health Community, 2026). If your Fitbit account is missing readings, Apple Health will be missing them too.
The older routes still work
- IFTTT (free tier available). A long-standing applet records every new weight logged by your Aria into the iOS Health app (the applet, live as of October 2026). It rides IFTTT's polling of the Fitbit API, so entries arrive on IFTTT's schedule, not at the moment you step off the scale.
- Paid bridge apps. Sync Solver, myFitnessSync, and SyncFit each log into your Fitbit account and write measurements — weight among them, and in several cases body fat percentage and BMI — into Apple Health. Sync Solver and SyncFit both shipped App Store updates in September 2026. The shared caveat, stated by the apps themselves: because of Fitbit's third-party API limits, syncing is mostly on the order of once a day.
- Historical import varies by bridge. myFitnessSync and SyncFit advertise full-history import from Fitbit; Sync Solver's documentation describes daily data. If Google Health doesn't bring your past readings across, a bridge that imports history may.
Pick one route. Running Google Health and a bridge at the same time can write the same weigh-in into Health twice.
The always-available fallback
An Aria is still a working instrument with a clear display. Read the number, then add the reading to Apple Health by hand — a manual entry is first-class in Health, with the same standing as anything an app writes. For a once-a-day weigh-in, this is the zero-dependency route that no API limit or app migration can break.
What lands where
| What Fitbit writes to Apple Health | What Apple Health can store | What Trendline reads from Health |
|---|---|---|
| Weight and body fat %, through the Google Health iPhone app (version 5.05 or later; Google's Apple Health FAQ). Bridges and IFTTT also write weight — some also body fat % and BMI. | 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 reads whatever your chosen route lands in Apple Health — Google Health, a bridge, IFTTT, or hand-entered — and also accepts manual entries for composition values Health has no type for.
Try the idea
You don't need the plumbing solved to see what a trend view adds: export or copy a few weeks of weigh-ins from the Fitbit app and paste them into the free weight trend calculator. The slower signal drawn under the raw readings is the payoff all this syncing is for.
Questions people ask
Can a Fitbit Aria sync to Apple Health?
Yes, with one app in the middle. An Aria weigh-in still travels from the scale to your Fitbit account first, and the Google Health app for iPhone can now write data into Apple Health (as of October 2026).
How do I turn on Apple Health syncing in Google Health?
Update the Google Health app on your iPhone to version 5.05 or later, the release that added Apple Health writing (MacRumors, August 3, 2026). In Google Health, open Connections, then Apps and services, and add Apple Health (the path MacRumors reported at launch), then allow Google Health to write Weight and Body Fat Percentage on the Health permission sheet.
Will my old Fitbit weigh-ins appear in Apple Health?
That is not documented. Neither Google's FAQ nor the launch coverage says whether weigh-ins from before you connect are copied into Apple Health, so check Health's weight chart after connecting.
Why is my Aria weigh-in missing from Apple Health?
Google doesn't document how quickly a new weigh-in appears in Health. If one is missing, open the Google Health app, because iOS limits how often apps sync in the background. If your Fitbit account is missing readings, Apple Health will be missing them too.
What if I can't use Google Health to sync my Aria?
The older routes still work: IFTTT, and the paid bridge apps Sync Solver, myFitnessSync, and SyncFit. The bridge apps themselves state that, because of Fitbit's third-party API limits, syncing is mostly on the order of once a day. You can also read the number on the Aria's display and add the reading to Apple Health by hand.
