Hi Rog, Wear 4 uses an intermediate app Health Services that take data from the hosted Health App, be it Samsung or Google. However it does not have Daily Activity that is a Samsung Health app.
I think you want this
com.samsung.android.shealthmonitor but I’m not sure. If that isn’t it
go to Play Store and download the Package names app . open it and you will see the apps that are installed on your phone.
or
Try running simple adb commands
adb connect 192.168.xxx.xxx:5555 (your watch IP address & enable debugging)
adb shell
pm list packages
You will get an output list like this
package:com.android.cts.priv.ctsshim
package:com.google.android.ext.services
package:com.android.providers.telephony
…
The app ID is the text after package:
