Huawei Watch 4 beats Apple Watch with blood sugar monitoring feature.

Huawei's newly launched Watch 4 has a non-invasive blood glucose monitoring feature that uses only a set of health metrics and does not require any additional hardware. The smartwatch will alert the wearer when it detects irregular blood sugar levels by measuring "10 health indicators in 60 seconds," including heart rate and pulse wave characteristics. This breakthrough technology has the potential to revolutionize the way people with diabetes manage their condition, but only if it is accurate and approved for public use by regulatory bodies.
