Analyst Jeff Pu predicts that Apple will introduce blood sugar monitoring in the Apple Watch Series 13, slated for 2027. He suggests Apple may market it as “Apple Watch featuring Blood Monitoring.” However, Pu has mixed accuracy in past release forecasts, so consumers should temper expectations.
Long Road to Glucose Tracking
Apple first explored non-invasive glucose tracking patents over a decade ago. For example, patents surfaced in 2018 and 2021 hinted at built-in sensors for measuring blood sugar without needles. Then in 2024, Apple ran trials of an insider app to collect blood sugar data for health studies. Despite these steps, Apple has yet to release a public feature.

Industry Competition and Challenges
Many firms chase non-invasive glucose monitoring. For instance, PreEvnt unveiled a breath-analysis clip-on device early in 2025. Moreover, established makers like Dexcom offer continuous monitors paired with Apple Watch apps today. However, integrating reliable sensors into a slim smartwatch remains a technical hurdle.
What Comes Next
Apple typically unveils major Watch upgrades at its fall events. Consequently, if Pu’s timeline holds, we may see prototype demos by late 2026. Meanwhile, Apple must secure regulatory approval for any medical-grade sensor. Then it will need to demonstrate accuracy comparable to existing glucose meters. Finally, Apple will likely partner with health institutions for research and validation.
User Impact and Outlook
If successful, blood sugar monitoring could transform diabetes management and general wellness tracking. For example, users could check glucose trends without finger pricks. Ultimately, this feature would position Apple Watch as a leading health device, blending convenience with vital medical insights.
