Can Apple Watch measure blood sugar? Current reality and timelines in 2026
Apple has pursued non-invasive blood glucose monitoring for years. Here's what actually works today, why the FDA still hasn't cleared a single smartwatch for this capability, and what it means for you if you have type 2 diabetes.

Few questions come up as often among Apple Watch users with type 2 diabetes as this one: can the watch measure my blood sugar? Given years of rumours about Apple's ambitions in this space, confusion is understandable. The short answer: not yet, and not in the near future either.
Current status: no blood glucose measurement
As of mid-2026, no Apple Watch can measure blood sugar non-invasively. This is not our estimate—it is the repeatedly confirmed position of the US FDA: no smartwatch or wearable-ring product on the market is approved for such measurement. If an app or accessory promises otherwise, be especially cautious.
What Apple is actually pursuing
Apple is reportedly pursuing an optical measurement approach: light is sent into the skin, and the system measures how glucose in tissue (interstitial fluid) affects certain light wavelengths. The project has been internally reorganised and now sits with a different team within Apple's engineering division. A market-ready product is not currently in sight.
Realistic timelines
Anyone hoping for a near-term glucose feature should temper expectations: realistic estimates point to 2028 to 2030 at the earliest for an initial trend display—a clinically reliable, accurate numerical measurement lies further in the future, if it arrives at all. No such announcement was expected at WWDC 2026, and the 2026 and 2027 models are likely to launch without this capability.
What this means for you with type 2 diabetes
Until a reliable, approved solution exists, your doctor-prescribed glucose meter or CGM system remains your only trustworthy tool for actual blood sugar readings. This will not change in the near term, regardless of which rumours are circulating.
What your wearable can already do is track the everyday factors around type 2 diabetes: sleep, activity, resting heart rate—all linked to insulin sensitivity, but not a replacement for actual glucose measurement.
Where Sam Health fits in
Sam reads resting heart rate, sleep, and activity from Apple Health and converts them into understandable trends compared against your personal baseline—deliberately without glucose data, which Apple Watch does not currently capture. For more on what these everyday factors mean in type 2 diabetes, see Resting heart rate, sleep, and activity in type 2 diabetes.

Frequently Asked Questions
Can Apple Watch currently measure blood sugar?+
No. As of mid-2026, no Apple Watch can measure blood sugar non-invasively. The US FDA has repeatedly confirmed that no smartwatch or wearable ring product on the market is approved for glucose measurement.
What is Apple actually working on?+
Apple is reportedly developing an optical measurement method: light is sent through the skin, and the system measures how glucose in the interstitial fluid affects certain light wavelengths. The project has been internally reorganised; a marketable product is not currently in sight.
When could a blood sugar feature arrive on Apple Watch?+
Realistic estimates point to 2028 to 2030 at the earliest for an initial trend-display function, with clinically reliable numerical measurements coming later, if at all. Do not bank on a near-term announcement.
What about apps or accessories promising non-invasive glucose reading?+
Be skeptical. To date, no commercially available non-invasive method is accurate enough for medical decision-making. For your actual glucose readings, rely on a device or CGM system prescribed by your doctor.
