Using Tizen Studio you can access the sensor data on the watch and by using the Android accessory protocol you can receive that data for use by a companion app on your mobile. This is not the same as Samsung Health data because of start times and algorithms in Samsung Health may be different.
So Tizen OS app on the watch, receiver app on the phone.
Samsung Health can be accessed on Android device but only runs in debug mode unless you are a Samsung Health Partner and that is next to impossible to become at this time.
