About this app

Sync your health data from Coros, Diabetes:M, Fitbit, Garmin, Google Fit, Withings, Oura, Polar, Samsung Health, Strava, Suunto and Huawei Health. You can sync to Diabetes:M, Fitbit, Google Fit, Health Connect, Samsung Health, Schrittmeister, FatSecret (weight only), Runalyze, Smashrun, Strava or Under Armour (MapMyRun etc.). Activity data can also be synced as FIT, TCX or GPX file to Google Drive. Health Sync works automatically and syncs the data in the background.

It will sync data from the time you first use the app. Historical data (all data before the day of installation) can be synced after the free trail period. You can't sync historical data from Polar (Polar doesn't allow this).

Warning: Samsung decided that no partner app can write steps to Samsung Health anymore. Reading steps data and other data, and writing other data will continue to work.

One week free trial

Health Sync is very easy to use. It offers you a one week free trial period. After the trial period, you can make a one-time purchase or start a six-month subscription to continue using Health Sync. For the Withings sync an additional subscription is required. The additional subscription is required due to recurring additional costs that we incur for this integration.

Just try the app and see if it fits your needs. What data you can sync depends on the source app from which you sync data, and the destination app(s) to which you sync the data.

You can choose different source apps for different types of data. For example: sync activities from Garmin to Samsung Health, and sync sleep from Fitbit to Samsung Health and Google Fit. After the first initialization actions, you can define the different sync directions.

Syncing between health data apps sometimes doesn't work as expected. Don't worry, almost all issues can be solved easily. You can check the Help Center menu in Health Sync. And if you can't solve the issue, you can send a Health Sync problem report (the last option in the Help Center menu), or send an email to You will get support to solve the sync issue.

UPDATE: I've been using this app to sync my Galaxy watch with Google fit for nearly a year now, and it's only gotten better with time. It continues to work very well and has gained great new features. I like this app a lot, and would recommend it to anyone who needs to sync health data from one app to another. It works flawlessly and seamlessly behind the scenes without me having to intervene at all.

I really like this app. It allows you to use multiple apps to keep track of fitness goals, since I have yet to find one app that does everything I want. I would like it if Steps and Exercise could be two completely separate sync categories. I also wish more things would sync both ways, but I suspect that is a weakness in the apps being synchronized rather than a fault of this app.

This app has been a technological godsend. When I first got my Samsung Watch and couldn't sync to Google Fit, I had some concerns. Very happy that I found this app and got it installed. Thus far there's only been one problem with the app, and that was when some the data was either doubling up or not syncing at all. Turns out that was due to having a Google Fit option still set to sync. Once I turned that off the app worked like a charm.

What's new

Added distance estimation when syncing indoor rowing from Huawei Health.

Fixed an issue with syncing activity data from Fitbit to Strava and some other apps when manually adding an activity to Fitbit.

Small improvements.
