If Fitbit data went missing after Google Health 5.12, start with the last sync time in the app. Try a manual sync and check the time again. If it stays the same, work through the iPhone connection checks below. If it moves forward and readings are still blank, check which dates and stats are affected before changing the pairing.
Google began rolling out Google Health 5.12 on November 6. On November 9, a Fitbit Charge owner reported that some readings were still on the tracker but had stopped appearing in the app. A Fitbit Air owner using iOS said their data reappeared after reinstalling the app, then stopped updating the next day. A community Product Expert said they escalated the reports. See Google’s release notes, the Fitbit Charge report, and the Fitbit Air report.
Check when your Fitbit last synced
- Find the last sync time. Keep your Fitbit near your iPhone. Open Google Health, tap Connections at the top left, then choose your Fitbit. Look below the device picture for the last sync time.
- Run a manual sync. Go to the Today tab and pull down on the screen. When syncing finishes, go back to the device page and see if the time changed.
- Open the missing stat. Check the date inside the affected tile, such as steps or sleep. If your tracker displays that stat, compare the tracker and app for the same date.
Google documents both ways to start a manual sync and where to find the timestamp in its Google Health sync guide for iPhone and iPad.
Use the result to pick your next check
| What you see | What to check next |
|---|---|
| The last sync time stays the same after a manual sync. | Check Bluetooth permissions, charge the tracker, and try again with it near your iPhone. |
| The last sync time updates, but one or more stats are blank. | Open the affected tiles and compare the dates. Check for an app update and record which stats still fail to appear. |
| Older history is also missing, or the wrong tracker appears. | Check that Google Health is using the Google Account you normally use with your Fitbit. |
| Google lists a Device Sync / Pairing incident. | Check the dashboard for updates. Try a manual sync after the incident is resolved. |
If the last sync time stays the same
- Check the tracker and phone. Charge the Fitbit if its battery is low. Keep it close to your iPhone and make sure the phone is online.
- Check Bluetooth access. On the iPhone, open Settings → Privacy & Security → Bluetooth. Allow Google Health to use Bluetooth. Then go to Settings → Bluetooth, switch it off briefly, and switch it back on.
- Check background syncing. If Fitbit only updates when you open the app, go to Settings → General → Background App Refresh and check that it is enabled for Google Health.
- Restart and retry. Restart your iPhone and open Google Health again. If the time still doesn’t change, use the restart instructions for your Fitbit model, then try another manual sync.
If other Bluetooth accessories also have trouble connecting, work through our iPhone Bluetooth troubleshooting guide.
If the sync time updates but the app still shows blanks
Compare the affected stat with other tiles. For example, today’s steps might update while last night’s sleep is still missing. Check whether the stat shows a reading for the date you expect. If sleep is the only missing item, see how to check sleep recording and syncing on a smartwatch.
Look for a Google Health update in the App Store. You can also check the Google Health Status Dashboard for a Device Sync / Pairing incident. If the problem continues, note your Fitbit model, iOS version, app version, last sync time, and which dates and stats are missing. Include those details when you contact Google Health support through the Google Health help page.
FAQs
Is Google Health the same app as the Fitbit app?
Yes. Google renamed the Fitbit app to Google Health. You still use it to sync your Fitbit tracker. See Google’s guide to the redesigned app.
How can I check a Fitbit with no screen?
Use the last sync time in Google Health. Run a manual sync and check whether the timestamp advances. Then open the affected tile and check the date of the newest reading.
Does a recent sync time mean every reading arrived?
The timestamp tells you when the device last synced. To see which readings arrived, open each affected stat and look at the dates inside it.
Should I reinstall Google Health?
Check the sync time, Bluetooth permissions, and App Store updates first. Google lists reinstalling as a later step and advises checking that your iPhone supports the current app version. If reinstalling brings your data back only briefly, tell Google Health support when the app stops updating again.
