Bloomberg’s Mark Gurman claims in his latest report that Apple is testing a blood sugar monitoring app designed to help pre-diabetics better manage their health and sugar levels. Apple is rumored to be working on a non-invasive blood sugar monitoring app, and now more evidence of that work is emerging.

Citing unnamed Apple sources (who spoke on condition of anonymity because the project is confidential), Gurman claims that Apple tested the app on certain employees. These employees were asked to confirm that they had prediabetes through a blood test that monitored blood sugar levels using a variety of commercially available devices. A blood test confirmed that these people did not currently have diabetes but were at high risk of developing type 2 diabetes.

Although there is no cure for diabetes, it can only be controlled, so prediabetes can be reversed with diet and appropriate exercise. That’s where Apple’s blood sugar monitoring app comes in, helping users see how their food choices can affect their sugar levels so they can make healthier food choices to prevent blood sugar spikes.

Apple reportedly has “no plans to release the app, but rather to integrate the technology into future health products,” such as a non-invasive blood glucose monitor. The report also notes that Apple’s noninvasive blood glucose sensor will emit laser light and inject it into the skin. Measure the amount of glucose in the blood.

It is claimed that the first versions of the technology warned users if they had prediabetes, while later versions will help users with certain blood sugar measurements. Apple has allegedly made significant progress in developing this technology, but it is still miles away from being market ready. As for the current situation, Gurman notes that Apple has suspended testing of the app to focus on other health features.
