Apple Watch health features have grown over the years. The latest rumor claims the Series 13 model in 2027 could measure blood sugar levels. This would mark a milestone for people who manage diabetes.
A long journey to glucose tracking
Since at least 2021, Apple has explored ways to include a blood sugar sensor. Reports at the time said a sensor was close to launch in the Series 7. That did not happen. In 2024, Apple tested an app in health studies but did not let the public use it. The new prediction comes from analyst Jeff Pu of KeyBanc. He names 2027 as the target for the Apple Watch with sugar tracking. Pu has shared accurate data before, though some forecasts have not come true.
How the watch might measure glucose
Traditional glucose monitoring needs a small blood sample. A non-invasive watch would use light or other signals on the skin. Apple has been granted patents for sensors that shine beams through tissue. These beams can detect sugar in blood beneath the skin surface. Similar technology appears in devices like the PreEvnt clip that reads breath to infer glucose levels. Apple’s system likely aims for greater accuracy and integration into its health app.
Why this feature matters
Diabetes affects hundreds of millions worldwide. Many people must prick their fingers many times a day. A continuous monitor in a wrist device would reduce pain and the risk of infection. It would also let users see real-time trends. That can help them adjust diet, activity, or insulin fast. Adding this sensor would strengthen the Apple Watch’s role as a health tool. It would push Apple further ahead of rivals in wearable health.
Challenges and ahead
Building a reliable sensor in the thin Apple Watch frame is hard. Light signals can scatter in skin and fat. Temperature changes and sweat can confuse readings. Apple must refine hardware and algorithms over the years of testing. It also needs approval from health regulators like the FDA before selling the feature to the public.
What to expect next
Work on glucose sensing may continue quietly in Apple labs. Public beta programs could test the app interface before the hardware is ready. Apple often announces new health features in spring events or at its June developer conference. If the target remains 2027, we may hear initial news by late 2026 about apps and study results.
Apple Watch Series 13 could become a vital health companion for people with diabetes and those who track their sugar for wellness. The road ahead will require patience, testing, and tight integration with the Apple Health ecosystem. But the potential benefits for users could be truly life-changing.
