I was thinking… with future Apple Watches rumored to get various health tracking features such as glucose monitoring, blood pressure sensing, sleep apnea monitoring, and the other possibilities, my only thought is Apple will turn all of these features into a monthly based subscription service in order to use them. What are your thoughts?
Looking it up, it traces back to a 2010 acquisition of a company called RareLight, and currently it is estimated (per Bloomberg and quoted here) that ‘hundreds of engineers’ are working on it.
While earlier in 2023 a ‘breakthrough’ had been talked about, it is still behind a secret development project, consuming many millions of $. And the device being worked on would be a "prototype device about the size of an iPhone that can be strapped to a person’s bicep.” So a very different thing altogether compared to the phone.
In the medical device business, plenty of existing companies for about a $10B business. Are they asleep regarding a non-invasive monitor? No way.
Still many years away…
