The file won’t open in SyncToHealth
SyncToHealth opens .fit files and ZIPs that contain them. TCX, GPX and CSV exports won’t work, so export again and choose Export File. If a FIT file still won’t open, tell us what the app says.
Guide
Get your files in.
Your activities are stored in Garmin Connect as FIT files. Here’s how to get them out and into SyncToHealth, one activity or your whole history.
One activity, all on your phone
On your iPhone
Use the Garmin Connect website in Safari, then hand the file straight to SyncToHealth.
In Safari, go to connect.garmin.com and sign in.
Open Activities, then All Activities, and tap the activity you want.
Tap the gear icon at the top right and choose Export File.
Tap Download. The ZIP goes to the Downloads folder in the Files app.
In Files, touch and hold the ZIP, tap Share and choose SyncToHealth.
SyncToHealth reads the FIT file inside and shows you a Receipt.
- Page too cramped? Tap the page menu in Safari’s address bar and choose Request Desktop Website.
- The Share button inside the Garmin Connect app shares your activity with people. Garmin’s help pages describe exporting the file only on the website, which is why this route uses Safari. If your version of the app offers the original file, share it to SyncToHealth the same way.
One activity, then send it to your iPhone
On a computer
Download the file on your Mac or PC, then move it to your iPhone.
Sign in at connect.garmin.com in any browser.
Choose Activities, then All Activities, and open the activity.
Click the gear icon at the top right and choose Export File.
A ZIP with the FIT file inside downloads to your computer.
Send it to your iPhone with AirDrop, or save it to iCloud Drive.
On your iPhone, open the file and choose SyncToHealth.
- Choose Export File, not TCX, GPX or CSV. Only the original file carries every sample.
- You can unzip it first and send only the
.fitfile. Either works.
Every activity at once, by email
Your whole history
Ask Garmin for a copy of your account data. It arrives as one Export Archive, and SyncToHealth reads every FIT file in it.
Open Garmin’s account data management page and sign in.
Choose Export Your Data, then Request Data Export.
Wait for the email with your download link. It usually takes about 48 hours, and can take up to 30 days.
Download the ZIP on your iPhone, or save it to iCloud Drive from a computer.
In Files, share the ZIP with SyncToHealth. No need to unzip it.
Your history is imported with a progress bar. If you leave, it picks up where it stopped.
- The archive also holds your profile and other account data. SyncToHealth reads only the FIT files and ignores the rest.
- It can be large. Keep your iPhone on Wi-Fi and give it a while.
Next time
Export often? Save a few taps.
Folder Watch
Make one folder in iCloud Drive, choose it once in SyncToHealth under Folder Watch, and save each new export there. New FIT files, up to two subfolders deep, are imported when you open the app, and sometimes in the background.
Shortcuts
“Import FIT files” is an action in the Shortcuts app. Give it files from the share sheet or a folder, and add it to a shortcut, Siri or the Action Button.
Something not right?
I got a .zip, not a .fit
That’s normal. Share or open the ZIP as it is and SyncToHealth reads the FIT files inside. If you’d rather see the file, tap the ZIP in Files to unzip it.
It says the activity is already imported
SyncToHealth recognises each activity by the identity inside its FIT file, so importing it again adds nothing twice. “Already in Apple Health” means another app wrote that workout first; here’s how to replace it with the complete one.
An activity is missing
- Check that it finished uploading: it should appear under All Activities on the Garmin Connect website.
- An account export only holds what was there when you asked for it. Export newer activities one by one.
- Activities typed in by hand, not recorded on a device, may have no FIT file to export.
- Deleted it in the Health app? SyncToHealth won’t bring it back on its own; tap Restore.
