Fitbit + Apple Health in 2026: Native Sync Is Here, and Most Advice Online Is Out of Date

70 BPM does not measure heart rate; it reads what Google Health (formerly the Fitbit app) has already written into Apple Health and lines it up with your calendar. So the useful question for Fitbit owners is not “is it compatible” but “what exactly does Google Health (formerly the Fitbit app) send, and how much of the day does it cover?” Everything below comes from Fitbit’s own support documentation, linked where quoted.

What Google Health (formerly the Fitbit app) writes to Apple Health

The heart-rate line on Fitbit’s official page reads, verbatim: “Vitals: Heart rate, Oxygen saturation, Respiratory rate, Resting heart rate, Blood glucose” (Google Health Help: Sync Google Health with Apple Health). See also Google Health Help: the Fitbit app is becoming the Google Health app.

The full export list on that page:

• Heart rate
• Resting heart rate
• Oxygen saturation and Respiratory rate
• Steps, Distance, Floors, Active calories, VO2 max
• Exercise and Exercise routes
• Sleep session and Sleep stages
• Weight and Fat percentage
• Body temperature, Nutrition, Water, Cycle health

The question that decides everything: does it cover the whole day?

Full-day heart rate: not documented by the maker. Heart rate and resting heart rate are on Google’s export list, so samples will arrive in Apple Health and 70 BPM will show them against your calendar. What Google’s documentation does not state is the sampling interval — whether you get a dense all-day trace like Garmin or Oura, or something sparser. Until Google publishes that, the honest answer is: connect it, then open Apple Health › Heart Rate for a full weekday and look at how the readings are spaced. That check takes two minutes and beats any assumption.

How to connect Google Health (formerly the Fitbit app) to Apple Health

From the Google Health app (this replaced the Fitbit app on 19 May 2026):

1. Open the Google Health app.
2. At the top left, tap Connections, then Apps and services.
3. Under “Add connections”, tap Apple Health.
4. Tap Get started.
5. On the “Sync Google Health with Apple Health” consent page, tap Agree.
6. Follow the prompts to authorise the connection and grant permissions.

Requirements from Google’s page: an iOS device on iOS 16.4 or later, signed in with an adult Google Account.

Once connected, open 70 BPM, grant it Apple Health read access for heart rate, and the samples Google Health (formerly the Fitbit app) has written appear on the day chart against your calendar events. 70 BPM shows every heart-rate sample in Apple Health, whichever device wrote it — it never filters by brand.

If Fitbit data is not showing up

Old advice says you need a bridge app

Before 2026, the Fitbit app had no native Apple Health sync and people used paid third-party bridge apps. That advice is now stale: native two-way sync landed in the Google Health iOS app in August 2026.

The app has a new name

Google’s page states the Fitbit app became the Google Health app starting 19 May 2026, with the update rolling out through 26 May. If you are looking for “Fitbit” in Apple Health’s Apps list, look for Google Health.

Historical import is limited

Google states the app reads three months of historical data from Apple Health. The page does not state how far back it exports.

How to check what you are actually getting

Open Apple Health › Browse › Heart › Heart Rate and switch to the day view. Readings scattered across an ordinary day mean all-day samples are arriving; readings clustered only into workout blocks mean you are getting session data only. Under the same screen, Data Sources & Access shows which app is writing. This check reflects your actual device, firmware and settings, and beats any compatibility page — including this one.

This article reflects Fitbit’s published documentation as read in September 2026. Sync behaviour changes; check the linked support page before relying on it. 70 BPM is not a medical device and does not diagnose anything.
