Apple reportedly tested a blood glucose monitoring app
Apple tested an internal app to help pre-diabetics manage blood glucose, but paused the trial.

Apple has reportedly been testing a new app aimed at helping individuals manage their blood glucose levels. The app was specifically targeted at pre-diabetic people and involved testing with employees known to be at risk of developing Type 2 diabetes through blood tests.
Participants monitored their blood sugar levels using various existing market devices, logging changes against their dietary intake. The app aimed to highlight relationships between certain foods and blood sugar changes, potentially advising users on food choices.
Although the trial was paused to prioritize other health features, there's speculation that insights from it could influence future Apple health products. Notably, this initiative is separate from Apple's ongoing efforts in developing non-invasive glucose monitoring technology and is not set for immediate consumer release.
