A watch can show readings sent by a separate glucose device, such as a continuous glucose monitor (CGM), but in that setup the separate device measures glucose. The watch is only displaying its data.
Can a smartwatch check your blood sugar by itself?
Not as a validated glucose measurement in the United States. In a safety communication issued on February 21, 2024, the FDA said it had not authorized, cleared, or approved any smartwatch or smart ring intended to measure or estimate blood glucose on its own. The agency also said it had not reviewed the safety and effectiveness of such standalone products. Read the FDA safety communication.

This is a statement about authorization and safety evidence, not a head-to-head test assigning an error rate to every watch. The FDA material does not provide an accuracy percentage for standalone watch claims. Do not treat a number from such a watch as a validated glucose result or use it to make diabetes medication decisions.
Why an inaccurate reading can be dangerous
The FDA warns that an inaccurate glucose value could contribute to medication errors. It specifically names insulin and sulfonylureas; a wrong reading can lead to dangerous hypoglycemia, confusion, coma, or death. A watch estimate should not replace a measurement from an appropriate glucose device or the care plan provided by a clinician.

What it means when a smartwatch shows glucose
A watch may display readings from a separate FDA-authorized device, including a CGM. A CGM pierces the skin and measures glucose; the watch or its app can serve as a screen for the readings. That is different from the watch measuring glucose itself. The FDA’s warning does not cover apps that display data from authorized devices such as CGMs.
Rank #2
Whether a particular watch, phone app, and CGM work together depends on the exact devices, software, and region. Compatibility for a specific combination is not established here, so check the device makers’ current compatibility information and local authorization details.

How the alternatives differ
| Option | What measures glucose | Does it pierce the skin? | Role of the smartwatch |
|---|---|---|---|
| Standalone smartwatch or smart ring claiming to measure glucose | No FDA-authorized standalone watch or ring for this purpose was identified in the FDA’s February 21, 2024 safety communication. | Not established by that FDA communication for every product; the key point is that these products do not directly test blood glucose. | It cannot be treated as a validated glucose meter. |
| CGM | The separate CGM measures glucose. | Yes; the FDA describes CGMs as separate glucose devices that pierce the skin. | May display readings if the exact system is compatible. |
| Home blood glucose meter | A handheld meter and test strips measure glucose in a small blood sample. | Yes; a small blood sample is required. | Not needed to perform the measurement. |
The FDA’s overview explains that meter accuracy depends on factors including meter and strip quality and how the test is performed. Follow the meter’s instructions and use new test strips authorized for sale in the United States. Ask a healthcare provider which meter is right for you.

What to do if your watch offers a glucose number
- Check whether the watch is displaying data from a separate glucose device or claiming to measure glucose by itself.
- If it is a standalone watch or ring claim, do not rely on that number for treatment or medication decisions.
- Use the glucose monitoring device recommended for your situation, and follow its instructions.
- Ask your healthcare provider about an FDA-authorized meter or CGM and how to interpret its readings.
- If you already use a CGM, verify compatibility for your exact watch, app, software, and region with the device makers.
What the FDA warning does—and does not—establish
The FDA communication establishes the agency’s stated U.S. authorization status as of February 21, 2024, and warns about relying on standalone watch and ring claims. It does not quantify the error of each product, establish clinical performance for individual models, or prove that every future noninvasive research approach is impossible. The practical point remains: a standalone watch reading is not an FDA-authorized glucose measurement.
