Apple Watch 13 may gain blood sugar monitoring in 2027

Glucose monitoring on an Apple Watch using a Dexcom app

The Apple Watch 13 in 2027 is rumored to be the first model to feature blood sugar monitoring, which Apple has rumored to be working on for years.

Even back with the Apple Watch Series 7 in 2021, there were reports that Apple had long been developing a blood sugar system that was then about to be launched. Nothing came of that, and in 2024 Apple was said to be trialing such an Apple Watch app, but for health data collection studies rather than public release.

Now analyst Jeff Pu has announced that blood sugar monitoring will be the key feature of the Apple Watch Series 13 in 2027. He suggests that it may be called "Apple Watch featuring Blood Monitoring," but offers no further details.

As reported on , Pu has solely listed dates for this feature. There is no indication of whether this comes from supply chain sources, or is an extrapolation based on Pu's previous reports about Apple.

Note that those previous reports have included correct information at times. Pu does, though, also have a history of declaring release schedules that tend to be wrong.

Apple has been consistently working to add health features to Apple Watch, and a notable one was blood oxygen level monitoring. However, that technology has been the subject of a patent dispute and is currently disabled on Apple Watches sold in the US.

Separately, Apple is far from the only company attempting to produce a blood sugar monitoring system that is non-invasive. In January 2025, PreEvnt previewed a clip-on device that works via breath analysis.

How amazing blood glucose monitoring would be on the watch. For everyone from diabetics to predisnetucs to those with blood pressure issues to folks monitoring diet correlations with fitness. Huge.

Hope it happens before 2027.

Add in blood alcohol monitoring and I’m sold on it.

Even if this required a CGM sensor you put on your arm, like a Lingo or Freestyle Libre, this would be huge. And now that such things are over-the-counter, it's totally doable.

So big set of micro needles in the back of it constantly taking blood sample? Will that not get a bit messy? Interesting and useful addition if they can pull it off.

It seems there's some non-invasive alternatives:

This kind would be usable in a smartwatch:

Their devices use radio frequencies and described as 1/3 the size of a smartphone. Either Apple would use a smaller integrated sensor or an accessory device, maybe a custom watch band.

This one uses a light beam to heat up the glucose in the skin and the temperature change shows the amount of glucose:

The sites say they are 95% as accurate as the blood testing strips. This would be a big improvement from having pins stuck in either regularly via finger testing or with the CGMs installed all the time.
