Apple engineers discussed all of the new synchronization features they added today within CareKit (19 minutes - end of the video). I was fortunate enough to make some contributions to this effort on CareKits official GitHub Page (I'm " cbaker6" 🙃)
The CareKitSample-ParseCareKit which shows off all of the tools at once. It combines the data sync tool (ParseCareKit) that syncs the data from your device to parse-hipaa. The sample app will have you synching data to your server in 3 minutes!
