It looks like Apple is still working on glucose management – ​​this time through software. BloombergMark Gurman tells the company tested an application this year for pre-diabetics, helping them manage their diet and lifestyle. Apple is said to have no plans to release the app to consumers, but it could play a role in future health products.

The company tested the app internally, and employees confirmed through a blood test that they were at risk of developing type 2 diabetes. The subjects “actively monitored their blood sugar through various commercially available devices” , recording the corresponding changes in glucose. The app would then note correlations between dietary changes and blood sugar levels (eg, “don’t eat the pasta”).

Gurman says Apple discontinued the test to focus on other health features. Bloomberg note that the Apple Health app doesn’t currently have meal tracking, something rival service offering. The publication also says that Apple may eventually offer deeper integration of third-party glucose tracking into its products.

The study was apparently not directly related to Apple’s 15-year attempt to deliver non-invasive blood glucose monitoringsomething that is seemingly regurgitated in Apple Watch rumors every cycle. It appears that the company’s current hardware prototype is a wearable device the size of an iPhone which uses lasers to shoot light into the skin. Gurman argues that Apple’s first consumer version — whether it’s the Apple Watch or some other form — will likely only notify users if they might be pre-diabetic. Delivery of specific glucose levels should occur in later iterations.
