Firstly, thanks for posting this article, I found it raises an interesting yet sometimes overlooked point: what scientific basis do these apps have in reality? I think it's apparent people trust their phones. When they're presented with data, it's implicit that it must be correct. You must have walked 12,121 steps - not one less or 50 more. It just...knows...right? Yet, the mental anguish of presenting this data and actions/consequence that may follow; what decisions to people make upon seeing this information? Do they book a GP appointment because their smartphone says they must? The Covid apps demonstrate this effect beautifully; apparently Bluetooth is such a well designed and implemented protocol people use it to judge whether to stay at home and isolate...As if I would ever trust what a smartphone says, there is not enough evidence and scientific backing to suggest data taken from sensors is even close to being accurate. Yet these apps were flouted as a way to 'help stop the spread', 'protect your loved ones'. We need legislation over any and all health apps, they need to prove their models and presented data is accurate (how the heck can it be? it's just a sensor, it doesn't 'know' anything). Easiest solution: turn these apps off, even better if you can: get rid of your smartphone. It's become a hostile enemy spy, not in your favor, but prides itself on selling you to anyone who wants it and supports an insidious industry. I'm getting used to not having mine with me all the time, I no longer use mobile telephony and mentally, it feels amazing. In the future this will be considered a revolution, as today your phone wants to try and determine every faucet of your life... Maybe it can estimate when I am likely to die, based on this 'data'? That'd be poetic.
