Sync your health data from Coros, Diabetes:M, Fitbit, Garmin, Google Fit, Health Mate (Withings), InBody, Oura, Polar, Samsung Health, Suunto and Huawei Health. You can sync to Diabetes:M, Fitbit, Google Fit, 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. 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 Health Mate (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 [email protected] You will get support to solve the sync issue.
