Can Garmin and Fitbit Connect? | What Syncs And What Doesn’t

No, these platforms don’t offer a native two-way sync, though some data can move across with third-party apps or manual export.

If you use a Garmin watch on some days and a Fitbit on others, the big question is simple: can both apps talk to each other and keep one clean health record? The plain answer is no, not in a built-in, automatic, full-account way.

Garmin Connect can link with many outside services, yet Garmin says most third-party links are one-way, and data received from one outside service is not forwarded to another. Fitbit also offers app connections, and on Android it can read shared health data through Health Connect. That means a partial bridge is possible, though it is not the same thing as a direct Garmin-to-Fitbit link.

So if you want your steps, workouts, weight, sleep, and heart rate to match perfectly in both apps, you’re likely to run into gaps. Some numbers may copy over. Some won’t. Some may show with delays, strange totals, or duplicates.

Can Garmin and Fitbit Connect? Here’s the real limit

The phrase “connect” can mean three different things, and that’s where many people get tripped up:

• Account link: one app is allowed to read data from another.
• Data sync: steps, workouts, weight, or sleep move across on a schedule.
• Two-way sync: both apps send data back and forth and stay matched.

Garmin and Fitbit do not offer that last option natively. There is no official toggle inside Garmin Connect or Fitbit that creates a clean, full, two-way sync between both brands.

Garmin’s page on third-party activity syncing says most outside services only receive data from Garmin Connect, and Garmin Connect does not forward incoming third-party data to other outside services. That one line tells you a lot. Even if Fitbit data reaches Garmin by some outside route, Garmin won’t then pass that same data onward as if it were native Garmin data.

Fitbit’s page on connecting Fitbit with another app says app links are available, and Android users can also use Health Connect to share health and fitness data across apps. That helps, though it still does not create an official Garmin-Fitbit pairing inside both ecosystems.

Garmin and Fitbit sync options on Android and iPhone

Your phone matters here. Android users have more room to patch things together because Fitbit works with Health Connect. iPhone users can still use third-party sync apps, though choices are slimmer and data paths are less tidy.

On Android, Health Connect can act like a middle layer. Fitbit can read or write selected health data there, based on your settings. Garmin Connect itself is not listed on Garmin’s official pages as a native Fitbit partner, so the result still depends on what another app can read and write.

On either phone type, third-party sync tools may move workouts, weight, or daily totals between services. That can help if your goal is “good enough” history in one dashboard. It is a bad fit if your goal is a perfect mirror image of both accounts.

What usually syncs and what often gets messy

Workouts tend to move more cleanly than all-day wellness stats. A run, ride, or walk has a start time, a duration, and a file. That makes it easier for outside apps to copy. Daily totals are messier. Steps, floors, calories, and sleep can be recalculated in different ways by each brand.

That’s why you may see one service show a workout while the other shows only calories. Or one app may count steps from the watch while the other counts phone motion too. Same day, same person, different totals.

Data type	What usually happens	Common snag
Recorded workouts	Often the easiest data to move with outside sync apps	Duplicate sessions if both apps log the same activity
Steps	May transfer as daily totals in some setups	Different counting methods cause mismatched numbers
Calories burned	May appear as summary data	Resting and active calories are handled differently
Heart rate	Limited transfer in many sync paths	Minute-by-minute data often stays in the original app
Sleep	One of the least reliable categories to move cleanly	Sleep stages and scoring may not carry over
Weight	Can be imported in some cases	Formatting rules and date issues can block import
Body measurements	Sometimes possible by export and import	Fields may not map neatly between brands
Badges and readiness scores	Usually stay locked to the original platform	Brand-specific features do not translate

When a Garmin-Fitbit setup makes sense

A mixed setup can still work well if you pick one app as your main record and treat the other as a device companion. That small shift saves a lot of frustration.

Say your Garmin watch is your training device, but you still wear a Fitbit for sleep. In that case, you can let Garmin Connect hold workout history and let Fitbit keep sleep history. You’re no longer trying to force two brands to tell the same story in the same way.

If you want more overlap than that, use a third-party sync app for a narrow job. Move workouts only. Or move weight only. The narrower the job, the fewer weird results you’ll see.

Best setup choices by goal

• One clean training log: keep Garmin Connect as the main record.
• One clean wellness log: keep Fitbit as the main record.
• Shared Android health dashboard: use Fitbit with Health Connect and grant only the data types you want.
• Historic Fitbit data inside Garmin: use Garmin’s import tool for exported Fitbit files.

That last one matters more than many people think. Garmin has an official page for importing Fitbit data into Garmin Connect. It is not a live sync. It is an import process, and Garmin notes that Fitbit CSV files need strict formatting. It also says Garmin data takes priority when both sources contain data for the same day.

That tells you the import tool is best for bringing over old records, not for keeping both apps tied together every day.

Your goal	Best route	What to expect
See Garmin workouts in another app	Third-party sync from Garmin Connect	Usually solid for activities, mixed for wellness stats
Pull Fitbit history into Garmin	Export Fitbit data, then import selected files to Garmin	Works for certain data sets, not a live feed
Keep one phone-based health hub on Android	Use Fitbit with Health Connect plus a compatible bridge app	Some shared data, with limits by app and permission
Make both accounts match line by line	No native method	Hard to keep clean over time

How to avoid duplicates and bad totals

If you do try a bridge app, set a few rules before you turn anything on.

Pick one source for each metric

Let one platform own steps. Let one own workouts. Let one own weight. Mixing sources for the same metric on the same day is where bad math starts.

Test with one day first

Don’t dump years of history into both systems right away. Sync one workout. Check the title, time, calories, and distance. Then decide if the result is good enough for your use.

Watch for brand-specific scores

Garmin metrics like Body Battery or training readiness and Fitbit metrics like Daily Readiness or sleep scores are built inside each brand’s own rules. Those values usually won’t carry over in a useful way.

Keep exports as a backup

If your main reason for linking both services is fear of losing history, export your data instead. Fitbit offers account export tools, and Garmin also gives you ways to keep activity files and account data. A backup is often more useful than a messy sync.

Should you try to connect Garmin and Fitbit at all?

If you only want one place to glance at trends, yes, a partial bridge can be worth it. If you want exact matching totals across both apps every day, it’s usually more trouble than it’s worth.

The cleanest move is to choose one brand as your main record, then use the other for the features you like most. Garmin tends to be stronger for training depth. Fitbit tends to feel simpler for everyday wellness tracking. Which one should sit in the center depends on how you use your watch, not on brand loyalty.

So, can Garmin and Fitbit connect? In a limited sense, yes. In a native, clean, two-way way, no. Once you know that line, the setup choices get much easier.
