Fitdigits apps, iCardio, iRunner, iWalker and iBiker do not currently, officially, support Samsung S Health as a data provider or partner. However, for people who would like to pair the S Health data and view it in your Fitdigits app and website, there is an unofficial link that can be created through a 3rd party app – Health Sync – that offers a bridge between data from S Health to Google Fit, then when Google Fit is paired with Fitdigits, the daily activity information is synced.
As this requires a third party app which we don’t control, we can’t officially support it. However, users have reported it works fairly well.
