OK all, just spoke to an incompetent customer service expert at Samsung who tried to convince me that the health monitor app is not available because my service provider has not approved it yet!! Upon further discussion she admitted that the app is not available for phones and devices other than Samsung (and perhaps not even all of them), and she could not tell me when it might be available to, this was just before she hung up on me, good work Samsung great customer service.
So in summary, Samsung have launched an upgrade to your wearable device but have not fully rolled out the app that allows you to use this upgrade, you may be lucky if you have a Samsung device and be able to use the upgrade but for a large number of people this just means you have a very expensive fitness tracker that doesn't do what Samsung promises it will.
Sorry about the rant but after 5 video chats and a few hours searching for a fix to have a customer service agent try and tell me it's my service provider blocking the download, because their product launch was ill timed has left me a bit upset!!!!
