Support

SyncFix is made by one developer, who reads every message.

Write to support@syncfix.olum.app. It helps to say which iOS version you have, which app or watch produced the file, and what you saw. Attach the file only if you are comfortable sharing it: it holds your route and heart rate.

Where do I get a workout file?

In your watch’s app or on its website, open the workout and look for Export, usually in a share or “more” menu. Take FIT when it is offered: it carries the most, including power, cadence, pauses, laps, calories and training effect. GPX and TCX work too.

Then share the file to SyncFix, or save it to Files and attach it on the import screen. Several files of the same workout can be attached together; where they overlap, FIT wins.

A file does not import

SyncFix reads FIT, GPX and TCX files that hold a single workout. An archive of many workouts is not supported in this version, and a multisport file has to be exported one leg at a time.

If a single-workout file still fails, send it over and say which app or watch produced it.

SyncFix cannot save to Apple Health

Saving needs permission to write Workouts. Open Settings → Apps → Health → Data Access & Devices → SyncFix and turn on Workouts in the list of what SyncFix may write. Any other type you leave off there, such as heart rate or routes, is left out of your imports.

Workouts are missing from the list

The list shows the workouts Apple Health lets SyncFix read. Check the read switches in the same place: Settings → Apps → Health → Data Access & Devices → SyncFix.

The workout shows twice in the Health app

That happens when another app’s thin copy was already there. SyncFix writes the complete workout and hides the thin one in its own list, but apps cannot delete each other’s data. To remove the duplicate, open Health, find the thin workout and delete it there.

The calories look wrong

When a file has no calories, SyncFix estimates them and marks the result with ~. An estimate is only as good as what it is computed from. In order: a power meter, speed and climbing on outdoor rides, heart rate with your VO2max, heart rate with a general formula, and last the sport’s MET value.

Every estimate except the one from power needs your body weight, from Apple Health or from Settings in SyncFix. You can switch the estimate off on the import screen.

I have a better file for a workout I already imported

Import it. SyncFix replaces its earlier copy instead of adding a second one.

How do I remove a workout SyncFix saved?

Open the workout in SyncFix and tap “Delete from Apple Health”. This removes the workout and everything SyncFix wrote with it, together with the copy SyncFix kept.

Where does my data go?

Nowhere. SyncFix has no account, no server and no analytics; the privacy policy has the details.
