Please have a look at the list of supported OS for Freedome here. Watch OS which is the OS of Apple Watch is not listed in the supported OS.
But there is a Freedome app on my Watch.
After trying here and there I found out that it just starts or stopps the iPhone app on the iPhone. So, I do not understand why a Watch app if it just turn ON/OF the iPhone app.
I thought it also protects when using the WiFi on the Watch but it seems to be not the case.
I deleted it already.
The link in question is only related to the supported iOS devices (iPhone & iPad) of which at the moment, Apple Watch is not part of.
We hope to be able to have on Apple Watch in the nearest future but as of now, there is no such support for it.
I checked with our team and the Freedome on your Apple watch would help to turn on or off Freedome on the iPhone.
