Bloomberg veteran Mark Gurman, who is known for his highly accurate reporting on Apple products, has just revealed that Apple is testing an application that can flexibly monitor blood sugar levels in real time, helping people with prediabetes to better control their health and blood sugar. In particular, this will be a non-invasive application, so it can be used extremely flexibly with many different users.
Gurman, citing anonymous Apple sources (who asked not to be named because the project is confidential), claims that Apple has been testing the app internally on a number of employees. These employees were asked to confirm that they were pre-diabetic via blood tests by monitoring their blood sugar levels using a variety of commercially available devices. The blood tests confirmed that they were not currently diabetic but were at high risk of developing type 2 diabetes.

Current medicine has not found a way to completely cure diabetes, but can only control and limit the progression of the disease. However, the pre-diabetes stage can be reversed through appropriate diet and exercise. This is where Apple's blood sugar tracking app comes into play, helping users see how different food choices can affect their blood sugar levels, thereby choosing a more suitable range of products, avoiding sudden spikes in blood sugar.
Apple aims to incorporate the technology into future health products, such as non-invasive blood glucose monitors. The report also notes that Apple’s non-invasive blood glucose sensor would shine a laser on the skin and read the amount of glucose in the blood.
Early versions of the technology will only be able to alert users if they are pre-diabetic. Later versions will be able to assess specific blood sugar levels for each individual. Apple is said to have made good progress with the technology, but it is still a long way from being commercially available.
