Would you like it if your Apple Watch told you that you’ve had enough to drink? That might be possible in future updates.
Apple recently partnered with Rockies Photonics. The company developes sensors for detecting blood-related health metrics such as blood pressure, blood glucose and blood alcohol levels.
Obviously, the glucose metric is of utmost importance. Imagine how invaluable this could be to diabetics! Also imagine if your Apple Watch could disable your car using CarPlay or call your designated driver when it knows that you should not drive. In this case, it would know better than you would after tossing back a few.
These updates would likely not be available until 2022.
