Description:
Apple has bold plans for the health trackers in its Apple Watch 7 and beyond, but we aren't convinced they'll ever become reality.

FULL STORY ======================================================================

Apple has a goal to ship an Apple Watch with more health tracking sensors
than ever and it could land as soon as 2022.

According to the Wall Street Journal , Apples vision of the future involves a smartwatch that can monitor blood pressure, temperature, sleep, and even
blood sugar on top of the data it already collects. However, its dreams of
the future might never match up with reality.

While Samsungs Galaxy Watch 3 and Galaxy Watch Active 2 already offer blood pressure tracking the feature has to be calibrated every four weeks with a typical blood pressure cuff, limiting its ease of use. Apple would likely
come under similar issues with reliability, especially as it reportedly wants to create a tracker that wont rely on squeezing the wrist which would make its device unlike every trustworthy blood pressure monitor available today.

Apple could find success with sleep tracking though, as this feature is already available on many of their rivals in the smartwatch and fitness tracker market. The only issue Apple will have run into so far with the features is battery life, as even the best Apple Watches arent consistently able to survive long enough to be used all day and all night reliably.

However, battery life is the least of Apples design problems if it wants to make a device that can be trusted to measure all this different medically important data. So unfortunately we arent expecting much from Apples 2022 smartwatches in this regard, and wed be surprised if it can ever develop the health features it reportedly wants to create. The science isnt in Apples corner

Apples desire to create a convenient, all-in-one health monitor is an admirable goal but its got more than a few challenges in its path, not least of which is developing the tech in question.

Apple isnt trying to create a monitor for something we cant already track medically, it's trying to create a whole new way of monitoring it something which isnt as easy as it first sounds.

Take blood sugar levels. There are currently only two methods we have of measuring it right now. One requires users to prick a finger and use the
blood in a short 15 second test, while the other requires a sensor to be inserted under the skin (though its currently less accurate than the prick).

Neither of these options would likely be what Apple wants to use, and developing a reliable blood sugar monitor that can work entirely from outside the body would be incredibly tricky. Apple would have to find a way to create a smartwatch-sized spectrometer-like device that can not only differentiate blood glucose from glucose in other areas (like glucose in the interstitial fluid that surrounds cells in our skin) but can accurately determine how much of that glucose is present per litre of blood. If it was easy, wed already be doing it.

If we ignore whether Apple could actually develop these devices or not for a second, it quickly falls into a second trap: space. Smartwatches already have to pack a fair amount into what is a surprisingly small form factor, and if Apple wants to add a bajillion new health trackers on top of that, we'll end up with an Apple Watch that looks like an arm bracer.

While we hope Apple is successful in its quest to make a health tracker
ripped straight out of science fiction, we wont be holding our breath. If its designs are even possible, we expect it would be years (if not decades)
before something as reliable and small as it needs to be actually comes to market, even with Apple throwing all its resources behind the project. The best cheap fitness trackers 2021
