I've been using Health Sync to sync data from SH into GF but as both Google and Samsung have released an app to make these things easier I thought I would give them a test.

Health Platform is supposed to allow the inport/export of data between different fitness apps but have noticed the apps are limited and don't always sync even if they are given permission.

Health Connect does not allow steps to be synced from SH. It has options for other areas of SH which I'm testing at the moment but not holding out much hope. Not sure why steps cant be synced. 

Overall it seems the third party app called Health Sync is still the better option to sync between SH and GF as you can include steps.

So is there any point using the apps from Google or Samsung?
