Google Health 5.08 Arrives: Fitbit Logins End as Google Account Becomes Mandatory

Google Health 5.08 may look like a small app update, but there is one important change that former Fitbit users should not ignore.

With version 5.08, Google Health now requires a Google Account. Legacy Fitbit account logins are no longer supported as Google completes the transition from the old Fitbit account system.

Even more importantly, Google says that unmigrated Fitbit data will be deleted. That makes this seemingly minor update much more important for people who still have old Fitbit data.

Google Health 5.08 Rolls Out on Android and iOS

Google Health 5.08 is rolling out to both Android and iOS. According to 9to5Google, this is one of the smallest updates since the major redesign that transformed the Fitbit app into Google Health in May 2026.

There is no dramatic interface redesign this time. Instead, Google is focusing on account management, sign-up reliability, stability, and bug fixes.

And honestly, this is one of those updates that may be more important than it looks.

1. Fitbit Account Login Is Officially Over

The biggest change in Google Health 5.08 is simple: Fitbit account credentials can no longer be used to sign in.

Users now need a Google Account to access Google Health.

This should not come as a complete surprise. Google has been moving Fitbit users toward Google Accounts for years, and the migration period has now ended.

So if you open Google Health after updating and discover that your old Fitbit login no longer works, it is not necessarily an app error.

It is part of Google's planned account transition.

2. What Happens to Old Fitbit Data?

This is probably the most important part of the update.

Google states that data that was not migrated from Fitbit will be deleted.

For users who have been collecting fitness and wellness information for years, that could be a big deal.

Think about your old activity history, sleep information, workouts, weight records, and other health-related metrics. Losing access to years of historical information is certainly not something most users want.

That is why the Google Account associated with your migrated Fitbit data matters.

3. Google Fixes a Sign-Up Problem

There is also a useful fix included in version 5.08.

Some users previously experienced problems when trying to sign up with an email address that had already been associated with a Fitbit account.

Google says this issue has now been fixed.

Users can now choose their preferred Google Account to sign in, even if the email address had previously been used with Fitbit.

That should make the transition considerably less frustrating for users who have old Fitbit account history.

4. A Small Update With a Big Account Change

At first glance, Google Health 5.08 does not sound exciting.

There is no major new dashboard. There is no headline-grabbing AI feature. There is no massive visual redesign.

But account infrastructure is one of those things users notice only when something stops working.

If someone still expects to log into Google Health using an old Fitbit account, the change could immediately become confusing.

That is why keeping your Google Account information organized is now more important than ever if you previously used Fitbit.

5. Google Health Is Becoming a Bigger Health Ecosystem

The account transition also highlights Google's broader strategy.

Google Health is no longer simply an app for checking basic fitness statistics. Google is positioning it as a centralized place for health and wellness information across compatible devices and services.

That makes wearable devices increasingly important because smartwatches and fitness trackers can continuously collect information that becomes useful inside a broader health ecosystem.

6. Does Google Health 5.08 Affect Android and iPhone Users?

Yes.

The update is being released for both Android and iOS.

The rollout status may differ between platforms, though. 9to5Google reports that the Android version is still rolling out, while the iOS update is fully available.

If you do not see the update immediately, there is no reason to panic. App updates can be distributed gradually.

7. Stability Improvements Are Included Too

Google Health 5.08 also includes general stability improvements and bug fixes.

That may sound like standard release-note language, but stability is particularly important after the major transition from Fitbit to Google Health.

The more users rely on Google Health as their central wellness dashboard, the more important it becomes for the app to remain reliable.

What Should Fitbit Users Do Now?

If you previously used Fitbit, it is worth checking a few things:

• Make sure Google Health is using a Google Account.
• Confirm that you are using the correct Google Account.
• Check whether your Fitbit data was successfully migrated.
• Update Google Health to the latest available version.
• Avoid creating a random new Google Account if your historical Fitbit data is already connected to another account.

The last point is especially important for people with years of Fitbit history. Your old health and fitness data may be much more valuable than you realize until you need it.

Final Thoughts

Google Health 5.08 may be a small update, but it marks a major milestone for the Fitbit-to-Google transition.

Legacy Fitbit account logins are no longer supported, and Google Accounts are now required for Google Health. Google also warns that Fitbit data that was not migrated will be deleted.

The update also fixes a sign-up issue involving email addresses previously associated with Fitbit, making it easier for affected users to choose their preferred Google Account.

So, if you are still using Fitbit or have years of Fitbit history, do not treat Google Health 5.08 as just another routine app update.

This is another clear sign that the old Fitbit account era is officially coming to an end.

And with Google continuing to expand its health, wearable, and AI ecosystem, Google Health could become an increasingly important part of how users manage their digital wellness data.

Are you still using a Fitbit device, or have you already moved completely to Google Health?
