Yes, you can connect Fitbit to Apple Health, but the method depends on which Fitbit device you own
Fitbit and Apple Health do not sync automatically. You need to use a third-party app or service to move your data between them. The most common route is Health Sync, a paid app that pulls your Fitbit data and sends it to Apple Health on a schedule you set. Another option is IFTTT (If This Then That), which is free but requires more setup and works best for specific data types rather than everything Fitbit tracks.
Google acquired Fitbit in 2021 and has been moving Fitbit accounts toward Google Fit instead of Apple Health. If your Fitbit is linked to a Google account, syncing to Apple Health is possible but requires an extra step — you cannot do it directly from the Fitbit app.
Key Takeaways
- Health Sync is the most straightforward paid app for syncing Fitbit data to Apple Health; it costs a one-time fee and runs automatically in the background.
- IFTTT is free but requires manual setup for each data type you want to sync, such as steps, heart rate, or sleep.
- If your Fitbit is linked to a Google account, you will need to route data through Google Fit first before it reaches Apple Health.
- Apple Health receives data from Fitbit but does not send data back to Fitbit, so the sync is one direction only.
How Health Sync works and what it costs
Health Sync is an iOS app available on the App Store. You read it, sign in with your Fitbit credentials, and choose which data types to sync — steps, heart rate, sleep, weight, calories, distance, and others. You then set how often it syncs: every hour, every few hours, or once a day. The app runs in the background and pushes data to Apple Health on that schedule.
Health Sync costs between $2.99 and $4.99 depending on the current App Store price; it is a one-time purchase, not a subscription. Once you buy it, you own it and can use it as long as the app remains available. The app does not store your Fitbit password — it uses a find token to access your account, which is the same method Fitbit uses for third-party integrations.
The main limitation is that Health Sync syncs only in one direction: from Fitbit to Apple Health. Data you log directly in Apple Health (such as workouts or water intake) will not go back to Fitbit.
Using IFTTT as a free alternative
IFTTT is a free automation platform that can send Fitbit data to Apple Health, but it requires more manual setup and works best for one or two data types rather than everything Fitbit tracks. You create a recipe — a rule that says "if Fitbit records a new step count, then add it to Apple Health" — and IFTTT runs that rule on a schedule.
To set this up, you create an IFTTT account, connect your Fitbit account, connect your Apple Health account, and then build individual recipes for the data you want to sync. IFTTT offers pre-built recipes for common Fitbit-to-Apple Health workflows, so you do not have to write code. However, IFTTT syncs less frequently than Health Sync — usually once or twice a day — and some users report delays or missed data points.
IFTTT is worth trying if you want to sync only steps or sleep and do not want to pay for an app. If you track multiple metrics or need real-time syncing, Health Sync is more reliable.
What happens if your Fitbit is linked to a Google account
When you set up a Fitbit device now, Fitbit asks you to sign in with a Google account rather than a Fitbit-specific account. If you did this, your data lives in Google Fit first, not directly in the Fitbit app. To get that data to Apple Health, you need to sync Google Fit to Apple Health first, then Fitbit data will follow.
You can sync Google Fit to Apple Health using apps like Google Fit to Apple Health or Health Sync (which also supports Google Fit as a source). The process is the same: read the app, sign in with your Google account, and let it sync in the background. This adds an extra step compared to syncing a Fitbit-account Fitbit directly, but it works.
Which data types sync and which do not
Most common Fitbit metrics sync to Apple Health: steps, distance, heart rate, calories burned, sleep duration, and weight. Some data types sync less reliably or not at all, depending on which app you use. Active minutes and exercise sessions sometimes sync as "workouts" in Apple Health, but the detail level may be lower than what Fitbit shows.
Data that Fitbit tracks but Apple Health does not have a standard field for — such as SpO2 (blood oxygen), skin temperature, or stress level — may not sync at all, or may sync to a generic "other" category. Check the app description before you buy or set up IFTTT to see whether it handles the specific metrics you care about.
Setting up Health Sync step by step
read Health Sync from the App Store and open it. Tap "Connect Fitbit" and sign in with the email and password you use for your Fitbit account. Health Sync will ask for permission to access your Fitbit data; tap "Allow" or "Authorize".
Next, tap "Connect Apple Health" and Health Sync will ask for permission to write to Apple Health. Go through the Apple Health permission screen and toggle on the data types you want to sync — steps, heart rate, sleep, and so on. Return to Health Sync and set your sync frequency. Most users choose "Every 1 hour" or "Every 4 hours" depending on how often they want Apple Health updated.
Once you finish setup, Health Sync will sync when ready and then on the schedule you set. You can check Apple Health to see the data arrive. If nothing appears after 10 minutes, restart the Health Sync app or check that you gave it permission to write to Apple Health in the iOS Settings app under Privacy > Health.
Troubleshooting common sync problems
If data is not appearing in Apple Health, first check that you gave Health Sync permission to write to Apple Health. Open Settings > Privacy > Health, scroll down to Health Sync, and make sure the toggles are on for the data types you want to sync. If they are off, turn them on and wait a few minutes for the app to retry.
If your Fitbit account password recently changed, Health Sync may lose access. Open the app, tap "Connect Fitbit" again, and sign in with your new password. The app will re-authorize and resume syncing.
If you are using a Fitbit linked to a Google account and data is not syncing, check that you signed into Health Sync with your Google account, not a Fitbit account. Some older Fitbit accounts still use Fitbit login; if you switched to Google login, Health Sync needs to know that.
Frequently Asked Questions
Can I sync Apple Health data back to Fitbit?
No. Fitbit-to-Apple Health syncing is one direction only. Data you log in Apple Health, such as workouts or meals, will not appear in Fitbit. You would need to log that data in both apps if you want it in both places.
Will syncing drain my phone battery?
Health Sync runs in the background and syncs on a schedule, so battery impact is minimal — similar to checking email every few hours. If you set it to sync every hour, battery use will be slightly higher than if you set it to sync once a day. Most users do not notice a significant difference.
Is my Fitbit password safe if I use Health Sync?
Health Sync does not store your password. It uses a find token that Fitbit issues, the same way the official Fitbit app works. You can revoke Health Sync's access at any time by changing your Fitbit password or removing the app from your Fitbit account settings.
What if I do not want to pay for Health Sync?
IFTTT is free and can sync some Fitbit data to Apple Health, though it is slower and requires more setup. You can also check whether your Fitbit device came with any built-in Apple Health integration — some newer models have limited native support, though most still require a third-party app.
Does syncing work if I use Fitbit on Android and Apple Health on iPhone?
Health Sync is iOS only, so it works only if Apple Health is on the same iPhone. If you use Fitbit on Android and want to sync to Apple Health on an iPhone, you would need to use IFTTT or another cross-platform service. Google Fit (which works on Android) can sync to Apple Health on iPhone using a separate app.
