  FitnessSyncer Historic Sync

There are some feeds which we will limit the amount of data we download from the source, or sometimes you have changes in your source system which you wish to re-import. For these sources, if you are a FitnessSyncer Pro user, you can do a Historic Sync to read all history from your sources. A Historic Sync is the one part of getting your history in that needs Pro: the recent history every source brings when you first connect it is free on any account.

  • From your account, click Edit     on the source you wish to run the Historic Sync on.
  • Depending on your selected experience:
    • On FitnessSyncer.com, click the icon from the toolbar.
    • On FitnessSyncer for Android, tap the icon at the top.
    • On FitnessSyncer for iOS, select the “Historic Sync” from the bottom of the screen.
    • Note: For Apple Health, Google Health Connect, and Samsung Health, Historic Sync is only available on FitnessSyncer.com and requires notifications enabled on your device.
  • Select your date range and whether you would like to be e-mailed at the end of the process.

We recommend that you read the FAQs for the providers that you use for any notes on limitations. Not all the providers have an option for Historic Sync.

The process can take minutes or days, depending on the source and the amount of data. While this is happening, we recommend that you do not change the source’s settings.

You can monitor the progress on FitnessSyncer.com by going back into the Source and selecting the icon from the toolbar, and this will provide you with the current range being worked on.

Once the data is available within FitnessSyncer, please review the data. The easiest way to do this is to open the FitnessSyncer Dashboard and change the dates for the range you have processed and ensure there are no gaps in it. Another useful tool is to export the CSV from the Source Editor and compare counts.

If you wish to send this data to an existing sync destination task, you will need to Reset the destinations to get the older data to flow to it.

How far back can I go?

When you first connect a service, every account, free or Pro, gets your recent history. For most services that is about the last 90 days; Dexcom gives about 30 days, and Polar starts from the day you connect. A Historic Sync then goes back for the rest, as far as each service allows:

ServiceHow far back a Historic Sync reachesAnother way to get the rest
Garmin Connect and Garmin Connect [China]Up to 5 years of activities and 2 years of health metrics.Garmin exports a summary CSV, or your whole account on request, for upload to FitnessSyncer Notebook. FIT files already on your computer come in through FitnessSyncer Uploader.
Polar FlowThe last 30 days, or since you connected, whichever is less. Polar hands over nothing from before you connected.All of it, by hand: Polar Flow exports your whole history as a ZIP from account.polar.com. Unzip it and upload the files to FitnessSyncer Notebook.
RouvyBack to January 1, 2023.
Dexcom CGMNot available. Your data starts from the day you connect.
BodyTraceNot available. Your data starts from the day you connect.

Every other service with Historic SyncEverything the service has kept.

If you are moving to FitnessSyncer from another service, Bring Your History walks through what arrives from Fitbit, Garmin, Samsung Health and Google Fit, and what to do when a service keeps nothing from before the day you connect.

If a Historic Sync did not do what you expected

  • You open it and are asked to upgrade. A Historic Sync needs FitnessSyncer Pro. The recent history a source brings when you first connect it is free on any account.
  • There is no icon at all. That service has nothing left for one to fetch, because a standard sync already brings all of your history in. If that does not sound right for your service, please contact us.
  • Nothing arrived, or it stops short of the date you asked for. The service decides how far back it will go, and several stop well before you do. The table above says where each one stops and what to do instead.
  • There are gaps in the range. Re-issue a Historic Sync for the gaps alone. Running the whole range again is slower and finds the same gaps.
  • Records you already had have not changed. A Historic Sync adds data; it does not overwrite what is there. Delete the original records and re-issue it.
  • The data is in FitnessSyncer but your destination did not get it. A destination only sends what it has not seen before, so Reset it to make it look again. Depending on the service and the amount of data, this can take some time.
  • It has been running for a long time. That can be normal: open the source and select the icon to see the range being worked on now. If it has not moved, please contact us.
