In past years, early fall is usually Apple’s launch time frame for new versions of it’s smartwatch.  And version 6 may even add blood oxygen monitoring alerts which can possibly result from COVID-19, flu, or other respiratory illnesses.

One of the reasons the Apple Watch has proved to be such a popular smartwatch is the fact it doubles as a health monitor, and it’s apparently going to get even better at doing that when the Apple Watch Series 6 launches later this year.  As 9To5Mac reports, leaked information via Digitimes suggests Apple has managed to secure the required hardware to include blood oxygen monitoring as a standard feature of the next Watch. The human body requires a very specific oxygen mix in our blood, with a healthy adult having a 95-100 percent mix.  Blood oxygen is therefore a great thing to be able to monitor.
